MIL-STD-490A SPECIFICATION PRACTICES ^

4 JUNE 1985

SUPERSEDING

MIL-STD-490

30 OCTOBER 1968

DISTRIBUTION STATEMENT A. Approved for public release; distribution is unlimited. Specification Practices

  1. This Military Standard has not been approved its use has to be with caution
  2. Recommended corrections, additions, or deletions should be addressed to:

Foreword ^

This Standard was prepared to establish uniform specification practices in response to the need for a document comparable to DOD-STD-100 covering engineering drawing practices and in recognition of the configuration identification concepts.

This Standard is arranged in six sections and 15 appendixes.

This Standard, although primarily intended for use in preparation of program-peculiar specifications, recognizes the probability that some items, processes, or materials covered by specifications prepared to this Standard will be subject to conversion on a project by project basis. Therefore, specifications prepared in accordance with this Standard, when subject to all pertinent conversion requirements.

Although this standard is specifically applicable to MIL-S-83490 Form 1a specifications only, its use as a guidance document for the preparation of other forms is encouraged.

1.0 SCOPE ^

1.1 Scope.

This standard establishes the format and contents of specifications for program-peculiar configuration items, processes, and materials.

1.2 Purpose.

The purpose of this standard is to establish uniform practices for specification preparation, to ensure the inclusion of essential requirements, and to aid in the use and analysis of specification content.

1.3 Classification.

Specifications covered by this standard may be prepared as military, Federal, contracting agency, or contractor specifications. The types of specifications are as follows:

1.4 Definitions.

1.4.1 Program-peculiar.

Configuration items, processes and materials as used in this standard, include all configuration items, processes and materials conceived, developed, reduced to practice or first documented for the development, procurement, production, assembly, installation, testing or support of the system/equipment/software/end product (including their components and supporting configuration items) developed or initially procured under a specific program.

For all Army applications of this standard, this paragraph shall read as follows:

PROGRAM-PECULIAR items, processes and materials as used in this standard, include only those items, processes and materials conceived, developed, reduced to practice or first documented for the development, procurement, production, assembly, installation, testing and support of the system/ equipment/end item (including their components and supporting items) developed or initially procured under a specific program for which there would be judged to be no potential for use by subsequently developed systems. In other words, program-peculiar items, processes and materials will be only those which are obviously only one-of-a-kind and, therefore, little or no potential exists for elimination through Item Reduction Studies or for any future use.'

1.4.2 Configuration item.

Hardware or software, or an aggregation of both, which is designated by the contracting agency for configuration management.

1.4.3 Hardware Configuration Item (HWCI).

See Configuration item.

1.4.4 Computer Software Configuration Item (CSCI).

See Configuration item.

1.4.5 Other definitions. For definitions of other terms used in this standard, see DOD-STD-480, Appendix E and DOD-STD-2167.

3.0 REQUIREMENTS ^

3.1 Introduction.

Specifications prepared in accordance with this standard are intended for use in design and procurement of configuration items and for services required for program- peculiar application.

3.1.1 Configuration identification.

Current configuration identification is established by baseline configuration identification documents and all effected changes. Configuration identification documents include all those necessary to provide a full technical description of the characteristics of the configuration item that require control at the time that the baseline is established (see 6.2).

3.1.1.1 Functional Configuration Identification (FCI).

Functional configuration identification (functional baseline and approved changes) will normally include a Type A specification or a Type B specification supplemented by other specification types as necessary to specify: (1) all essential system functional characteristics; (2) necessary interface characteristics; (3) specific designation of the functional characteristics of key configuration items; and (4) all of the tests required to demonstrate achievement of each specified characteristic (see 6.2).

3.1.1.2 Allocated Configuration Identification (ACI).

Allocated configuration identification (allocated baseline and approved changes) normally consists of a series of Type B specifications defining the requirements including functional, for each major configuration item. These may be supplemented by other types of specifications, engineering drawings and related data, as necessary, to specify: (1) all of the essential configuration item characteristics including delineation of interfaces;(2) physical characteristics necessary to assure compatibility with associated systems, configuration items and inventory items; and (3) all of the tests required to demonstrate achievement of each specified functional characteristic (see 6.2).

3.1.1.3 Product Configuration Identification (PCI).

The product configuration identification (product baseline and approved changes) will normally include specification Types C, D, and E, engineering drawings and related data, as necessary, to provide a set of documents adequate for the procurement, production, test, evaluation, and acceptance of a configuration item without requiring further development work. This set of documents provides that technical description which describes the required physical characteristics of a configuration item; the functional characteristics designated for production acceptance testing; and required acceptance tests.

3.1.2 Coverage of specifications.

Specifications may be prepared to cover a group of products, services or materials, or a single product, service or material, and are general or detail specifications, respectively, and either may be prepared as any of the types specified herein.

3.1.2.1 General specification. A general specification covers requirements common to two or more types, classes, grades, or styles of products, services, or materials; this avoids repetition of common requirements in detail specifications. It also permits changes to common requirements to be readily effected. General specifications may also be used to cover common requirements for weapon systems and subsystems.

3.1.2.2 Detail specification.

A detail specification covers all requirements for one or more types of configuration items or services so as not to require preparation and reference to a general specification for the common requirements. A detail specification may also take the form of a specification sheet, which is incomplete without reference to a general specification. The detail and referenced general specification (which contains the requirements common to the family configuration items) then constitute the total requirements. In either instance, detail specifications shall be prepared in six-section format described in Section 3 and 4 of this standard.

3.1.3 Types.

General Requirements for specification types are as follows:

3.1.3.1 Type A - System/subsystem specification.

This type of specification states the technical and mission requirements for a system/subsystem as an entity, allocates requirements to functional areas, documents design constraints, and defines the interfaces between or among the functional areas. Normally, the initial version of a system/subsystem specification is based on parameters developed during the Concept Exploration phase. This specification (initial version) is used to establish the general nature of the system that is to be further defined and finalized during the Demonstration and Validation phase. The system/subsystem specification is maintained current during the Demonstration and Validation phase, culminating in a revision that forms the future performance base for the development and production of the prime items and configuration items. The System/Subsystem Specification shall be prepared by the contractor and shall be in accordance with the format and content of the System/ Subsystem Specification Data Item Description (see 6.2).

3.1.3.2 Type B - Development specifications.

Development specifications state the requirements for the design or engineering development of a product during the development period. Each development specification shall be in sufficient detail to describe effectively the performance characteristics that each configuration item is to achieve when a developed configuration item is to evolve into a detail design for production. The development specification should be maintained current during production when it is desired to retain a complete statement of performance requirements. Since the breakdown of a system into its elements involves configuration items of various degrees of complexity which are subject to different engineering disciplines or specification content, it is desirable to classify development specifications by sub-types. The characteristics and some general statements regarding each sub-type are given in the following paragraphs (see 6.2).

3.1.3.2.1 Type B1 - Prime item development specification.

(See Appendix II for outline of form). A prime item development specification is applicable to a complex item such as an aircraft, missile, launcher equipment, fire control equipment, radar set, training equipment, etc. A prime item development specification may be used as the functional baseline for a single configuration item development program or as part of the allocated baseline where the configuration item covered is part of a larger system development program. Normally configuration items requiring a Type B1 specification meet the following criteria:

  1. The prime item will be received or formally accepted by the contracting agency on a DD Form 250, sometimes subject to limitations prescribed thereon.
  2. Provisioning action will be required.
  3. Technical manuals or other instructional material covering operation and maintenance of the prime item will be required.
  4. Quality conformance inspection of each prime item, as opposed to sampling, will be required.

3.1.3.2.2. Type B2 - Critical item development specification. (See Appendix III for outline of form.) A Type B2 specification is applicable to a configuration item which is below the level of complexity of a prime item but which is engineering critical or logistics critical.

  1. A critical item is engineering critical where one or more of the following applies:
    • The technical complexity warrants an individual specification.
    • Reliability of the critical item significantly affects the ability of the system or prime item to perform its overall function, or safety is a consideration.
    • The prime item cannot be adequately evaluated without separate evaluation and application suitability testing of the critical item.
  2. A critical item is logistics critical where the following apply:
    • Repair parts will be provisioned for the item.
    • The contracting agency has designated the item for multiple source reprocurement.

3.1.3.2.3 Type B3 - Non-Complex item development specification.

(See Appendix IV for outline of form.) This type of specification is applicable to configuration items of relatively simple design which meet all of the following criteria:

  1. During development of the system or configuration item, the non-complex item can be shown to be suitable for its intended application by inspection or demonstration.
  2. Acceptance testing to verify performance is not required.
  3. Acceptance can be based on verification that the item, as fabricated, conforms to the drawings.
  4. The end product is not software.

Examples of configuration items which normally meet the above criteria are: special tools, work stands, fixtures, dollies, and brackets. Many such simple configuration items can be defined adequately during the development phase by a sketch and during production by a drawing or set of drawings. If drawings will suffice to cover all requirements, and unless a specification is required by the Government contracting agency, a specification for a particular non-complex item need not be prepared. However, when it is necessary to specify several performance requirements in a formal manner to ensure development of a satisfactory configuration item or when it is desirable to specify detailed verification procedures, the use of a specification of this type is appropriate.

3.1.3.2.4 Type B4 - Facility or ship development specification.

(See Appendix V for outline of form.) A facility or ship development specification is applicable to each HWCI which is both a fixed (or floating) installation and an integral part of a system. Examples of facility/ship requirements are: basic structural, architectural or operational features designed specifically to accommodate the requirements unique to the system and which must be developed in close coordination with the system; the facility or ship services which form complex interfaces with the system; facility or ship hardening to decrease the total system's vulnerability; and ship speed, manoeuvrability, etc. A development specification for a facility or ship establishes the requirements and basic restraints/constraints imposed on the development of an architectural and engineering design for such facility or ship. The product specifications for the facility or ship are prepared by the architectural/engineering activity, and their type and format are not prescribed by this standard.

3.1.3.2.5 Type B5 - Software development specification

(see 6.2). Software development specifications are applicable to the development of computer software and consist of a Software Requirements Specification and Interface Requirements Specification(s)..

3.1.3.2.5.1 Software Requirements Specification.

This type of specification describes in detail the functional, interface, quality factor, special, and qualification requirements necessary to design, develop, test, evaluate and deliver the required Computer Software Configuration Item (CSCI). The Software Requirements Specification shall be prepared by the contractor and shall be in accordance with the format and content of the Software Requirements Specification Data Item Description (See 6.1). .

3.1.3.2.5.2 Interface Requirements Specification.

This type of specification describes in detail the requirements for one or more CSCI interfaces in the system, subsystem, or prime item. The specified requirements are those necessary to design, develop, test, evaluate, and deliver the required CSCI. The interface requirements may be included in the associated Software Requirements Specifications under the following conditions: (1) there are few interfaces, (2) few development groups are involved in implementing the interface requirements, (3) the interfaces are simple, or (4) there is one contractor developing the software. The Interface Requirements Specification shall be prepared by the contractor(s) and shall be in accordance with the format and content of the Interface Requirements Specification Data Item Description (see 6.2). .

3.1.3.3 Type C - Product Specifications.

Product specifications are applicable to any configuration item below the system level, and may be oriented toward procurement of a product through specification of primarily functional (performance) requirements or primarily fabrication (detailed design) requirements. Sub-types of product specifications to cover equipments of various complexities or requiring different outlines of form are covered in paragraphs 3.1.3.3.1 through 3.1.3.3.5.

  1. A product function specification states (1) the complete performance requirements of the product for the intended use, and (2) necessary interface and interchangeability characteristics. It covers form, fit, and function. Complete performance requirements include all essential functional requirements under service environmental conditions or under conditions simulating the service environment. Quality assurance provisions for hardware include one or more of the following inspections: qualification evaluation, preproduction, periodic production, and quality conformance.
  2. A product fabrication specification will normally be prepared when both development and production of the HWCI are procured. In those cases where a development specification (Type B) has been prepared, specific reference to the document containing the performance requirements for the HWCI shall be made in the product fabrication specification. These specifications shall state: (1) a detailed description of the parts and assemblies of the product, usually by prescribing compliance with a set of drawings, and (2) those performance requirements and corresponding tests and inspections necessary to assure proper fabrication, adjustment, and assembly techniques. Tests normally are limited to acceptance tests in the shop environment. Selected performance requirements in the normal shop or test area environment and verifying tests therefore may be included. Preproduction or periodic tests to be performed on a sampling basis and requiring service, or other, environment may reference the associated development specification. Product fabrication specifications may be prepared as Part II of a two-part specification (See 3.1.4) when the contracting agency desires close relationships between the performance and fabrication requirements.

3.1.3.3.1 Type C1 -Prime item product specifications.

Prime item product specifications are applicable to configuration items meeting the criteria for prime item development specifications (Type B1) as stated in paragraph 3.1.3.2.1. They may be prepared as function or fabrication specifications as determined by the procurement conditions..

3.1.3.3.1.1 Type C1a - Prime item product function specification.

(See Appendix VII for outline of form.) A type C1a specification is applicable to the procurement of prime items when a 'form, fit and function' description is acceptable. Normally, this type of specification would be prepared only when a single procurement is anticipated and training and logistic considerations are unimportant..

3.1.3.3.1.2 Type C1b - Prime item product fabrication specification.

(See Appendix VIII for outline of form.) Type C1b specifications are normally prepared for procurement of prime items when: a detailed design disclosure package needs to be made available; it is desired to control the interchangeability of lower level components and parts; and service maintenance and training are significant factors..

3.1.3.3.2 Type C2 - Critical item product specifications.

Type C2 specifications are applicable to engineering or logistic critical items as specified in paragraph 3.1.3.2.2, and may be prepared as function or fabrication specifications..

3.1.3.3.2.1 Type C2a - Critical item product function specification.

(See Appendix IX for outline of form.) A type C2a specification is applicable to a critical item where the critical item performance characteristics are of greater concern than part interchangeability or control over the details of design, and a 'form, fit and function' description is adequate.

3.1.3.3.2.2. Type C2b - Critical item product fabrication specification.

(See Appendix X for outline of form.) A C2b specification is applicable to a critical item when a detailed design disclosure needs to be made available or where it is considered that adequate performance can be achieved by adherence to a set of detail drawings and required processes..

3.1.3.3.3 Type C3 - Non-complex item product fabrication specification.

(See Appendix XI for outline of form.) A non-complex item product fabrication specification is applicable to non-complex items as specified in paragraph 3.1.3.2.3. Where acquisition of a non-complex item to a detailed design is desired, a set of detail drawings may be prepared in lieu of a specification..

3.1.3.3.4 Type C4 - Inventory item specification.

(See Appendix XII for outline of form.) This type of specification identifies applicable inventory items (including their pertinent characteristics) that exist in the DOD inventory and which will be incorporated in a prime item or in a system being developed. The purpose of the inventory specification is to stabilize the configuration of inventory items in the DOD inventory on the basis of both current capabilities of each inventory item and the requirements of the specific application, or to achieve equipment/component item standardization between or within a system or prime item. This puts the Government on notice as to the performance and interface characteristics that are required, so that when ECP's for an inventory item are evaluated the needs of the various applications may be kept in mind. If this is not done, design changes may make an inventory item unsuitable for the system. A separate inventory item specification should be prepared, as required, for each system, subsystem, prime item or critical item in which inventory items are to be installed or which require the support of inventory items..

3.1.3.3.5 Type C5 - Software Product Specification (see 6.2).

The Software Product Specification is applicable to the delivered CSCI and is sometimes referred to as the 'as built' software specification. This specification consists of the final updated version of the Software Design Description, the Software Design Description, the Data Base Design Description(s), the Interface Design Description(s), and the source and object listings of the software. The Software Product Specification shall be prepared by the contractor and shall be in accordance with the format and content of the Software Product Specification Data Item Description (see 6.2)..

3.1.3.3.5.1 Software Design Description.

The Software Design Description describes how the top-level software units implement requirements allocated from the Software Requirements Specification and, if applicable, Interface Requirements Specification(s). The Software Design Description shall be prepared by the contractor and shall be in accordance with the format and content of the Software Design Description Data Item Description (see 6.2). .

3.1.3.3.5.2 Software Design Description.

The Software Design Description shall also describe the detailed decomposition of high level software units to lower level software units. The Software Design Description shall be prepared by the contractor and shall be in accordance with the format and content of the Software Design Description Data Item Description (see 6.2)..

3.1.3.3.5.3 Data Base Design Description.

The Data Base Design Description describes one or more data base(s) used by the CSCI. If there is more than one data base, each data base may be described in a separate Data Base Design Description. The Data Base Design Description(s) shall be prepared by the contractor and shall be in accordance with the format and content of the Data Base Design Description Data Item Description (see 6.2)..

3.1.3.3.5.4 Interface Design Description.

The Interface Design Description provides the detailed design of one or more CSCI interfaces. When Interface Requirements Specifications have been prepared, associated Interface Design Descriptions shall be prepared as well. The Interface Design Description shall be prepared by the contractor and shall be in accordance with the format and content of the Interface Design Description Data Item Description (see 6.2). .

3.1.3.4 Type D - Process specifications.

(See Appendix XIV for outline of form.) This type of specification is applicable to a service which is performed on a product or material. Examples of processes are: heat treatment, welding, plating, packing, microfilming, marking etc. Process specifications cover manufacturing techniques which require a specific procedure in order that a satisfactory result may be achieved. Where specific processes are essential to fabrication or procurement of a product or material, a process specification is the means of defining such specific processes. Normally, a process specification applies to production but may be prepared to control the development of a process..

3.1.3.5 Type E - Material specifications.

(See Appendix XV for outline of form.) This type of specification is applicable to a raw material (chemical compound), mixtures (cleaning agents, paints), or semi-fabricated material (electrical cable, copper tubing) which are used in the fabrication of a product. Normally, a material specification applies to production but may be prepared to control the development of a material..

3.1.4 Two-part specifications.

Two-part specifications, which combine both development (performance) and product fabrication (detail design) specifications under a single specification number as Part I and Part II respectively, may be selected as a contracting agency option. This practice requires both parts for a complete definition of both performance requirements and detailed design requirements governing fabrication. Under this practice, the development specification remains alive during the life of the HWCI as the complete statement of performance requirements. Proposed design changes must be evaluated against both the product fabrication and the development parts of the specification. To emphasize the fact that two parts exist, both parts shall be identified by the same specification number and each part shall be further identified as Part I or Part II, as appropriate. Two-part specifications are not applicable when the product specification is a product function specification or when it is a computer software specification..

3.2 Style, format and identification of specifications.

3.2.1 General.

This section covers style, format, and general instructions for preparing a specification. This includes material arrangement, paragraphing, numbering, heading, and concluding material..

3.2.2 Sectional arrangement of specifications.

Specifications shall contain six numbered sections, and appendixes as required, titled and numbered as shown below.

  1. SCOPE
  2. APPLICABLE DOCUMENTS
  3. REQUIREMENTS
  4. QUALIFICATION REQUIREMENTS (for software)
     or QUALITY ASSURANCE PROVISIONS (for hardware)
  5. PREPARATION FOR DELIVERY
  6. NOTES,
 10. APPENDIX

Subject matter shall be kept within the scope of the sections so that the same kind of requirements or information will always appear in the same section of every specification. Except for appendixes, if there is no information pertinent to a section, the following shall appear below the section heading:.

'This section is not applicable to this specification.'.

3.2.3 Language style.

The paramount consideration in a specification is its technical essence, and this should be presented in language free of vague and ambiguous terms and using the simplest words and phrases that will convey the intended meaning. Inclusion of essential information shall be complete, whether by direct statements or references to other documents (See 3.1.4). Consistency in terminology and organization of material will contribute to the specification's clarity and usefulness. Sentences shall be as short and concise as possible. Punctuation should aid in reading and prevent misreading. Well-planned word order requires a minimum of punctuation. When extensive punctuation is necessary for clarity, the sentence(s) shall be rewritten. Sentences with compound clauses shall be converted into short and concise sentences..

3.2.3.1 Capitalization, spelling, etc.

Except where DOD requirements differ, the United States Government Printing Office Style Manual shall be used as a guide for capitalization, spelling, punctuation, syllabification, etc. Merriam-Webster's New International dictionary (latest revision) will be consulted when the Style Manual does not provide the guidance needed. .

3.2.3.2 Abbreviations.

The applicable standard abbreviations listed in MIL-STD-12 shall be used, except that abbreviations in titles of specifications shall be in accordance with Cataloging Handbook H6-1. The only other abbreviations employed shall be those in common usage and not subject to misinterpretation. The first time an abbreviation is used in text, it shall be placed in parentheses following the word or term spelled out in full; e.g., pounds per square inch (psi). This rule does not apply to abbreviations used for the first time in tables and equations; uncommon abbreviations so used shall be explained in the text or footnotes..

3.2.3.3 Symbols.

Symbols shall not be used in text, but may be used in equations and tables. Graphic symbols, when used in figures shall be in accordance with military standards. (Any symbol formed by a single character should be avoided if practicable, since an error destroys the intended meaning.).

3.2.3.4 Proprietary names.

Trade names, copyrighted names, or other proprietary names applying exclusively to the product of one company shall not be used unless the configuration item(s) require source control or cannot be adequately described because of the technicality involved, construction, or composition. In such instances, one, and if all pertinent requirements are specified, several, commercial products may be included by inserting the words 'or equal' after the trade name to assure wider competition and that bidding will not be limited to a particular make specified. The same applies to manufacturer's part numbers or drawing numbers for minor parts when it is impractical to specify all detail requirements in the specification. In all instances where 'or equal' is permitted, the particular characteristics required shall be included to define 'or equal'. .

3.2.3.5 Commonly used words and phrasing.

Certain words and phrases are frequently used in a specification. The following rules shall be followed:

  1. Referenced documents shall be cited thus 'conforming to ...' 'as specified in ...' or 'in accordance with ...'.
  2. 'Unless otherwise specified' shall be used to indicate an alternative course of action. The phrase shall always come at the beginning of the sentence, and if possible, at the beginning of the paragraph. This phrase shall be used only when it is possible to clarify its meaning by providing a reference such as to Section 6 of the specification for further clarification in the contract or order or otherwise.
  3. When making reference to a requirement in the specification and the requirement referenced is rather obvious or not difficult to locate, the simple phrase 'as specified herein' is sufficient and should be used.
  4. The phrase '... to determine compliance with ...' or '... to determine conformance to ...' should be used in place of '... to determine compliance to ...'. In any case use the same wording throughout.
  5. In stating positive limitations, the phrase shall be stated thus: 'The diameter shall be no greater than ...'.
  6. The emphatic form of verb shall be used throughout the specification; i.e., state in the requirements section that 'The indicator shall be designated to indicate ...', and in the section containing test provisions 'The indicator shall be turned to zero and 230 volts alternating current applied.' For specific test procedures, the imperative form may be used provided the entire method is preceded by 'the following tests shall be performed,' or related wording. Thus, 'Turn

    the indicator to zero and apply 230 volts alternating current.'

  7. Capitalize the words 'drawing,' 'bulletin,' etc., only when they are used immediately preceding the number of a document. However, Federal and military standards, and handbooks shall be identified in the text only by their symbol and number; thus 'MIL-E-000,' not, 'specification MIL-E-OOO.'

3.2.3.6

Use of 'shall,' will,' 'should,' and 'may'. Use 'shall' whenever a specification expresses a provision that is binding. Use 'should' and 'may' wherever it is necessary to express non-mandatory provisions. 'Will' may be used to express a declaration of purpose on the part of the contracting agency. It may be necessary to use 'will' in cases where the simple future tense is required, i.e., power for the motor will be supplied by the ship..

3.2.3.7

Use of 'flammable' and 'non-flammable'. The terms 'flammable' and 'non-flammable' shall be used in specifications in lieu of the terms 'inflammable', 'uninflammable', and 'non-flammable'..

3.2.4

Paragraph numbering. Each paragraph and subparagraph shall be numbered consecutively within each section of the specification, using a period to separate the number representing each breakdown. Example for Section 3 of specification:.

 3. REQUIREMENTS

 3.1 First Paragraph.

 3.1.1 First Subparagraph.

 3.2 Second Paragraph.

 3.2.1 First Subparagraph.

 3.2.2 Second Subparagraph.

 Or:.

 3. REQUIREMENTS.

 3.1 First Paragraph.

 3.1.1 First Subparagraph.

 3.2 Second Paragraph.

 3.2.1 First Subparagraph.

 3.2.2 Second Subparagraph.

Itemization with a paragraph or subparagraph shall be identified by lowercase letters to avoid confusion with paragraph numerals. For clarity of text, paragraph numbering shall be limited to seven levels..

3.2.5 Paragraph identification.

If practicable, each paragraph and subparagraph shall be given a subject identification. The first letter of the first word in the paragraph identification shall be capitalized. Paragraph identifications in any one section shall not be duplicated. Primary paragraphs identifications shall be in boldfaced type and subparagraph identifications italicized when typeset. When typewritten, paragraph identification shall be underlined.

3.2.6 Underlining.

Do not underline any portion of a paragraph or capitalize phrases or words for the sake of emphasis with the exceptions noted in 3.2.5. All of the requirements are important in obtaining the desired product or service. .

3.2.7 Cross references.

Cross references, that is references to parts within the specification, shall be held to a minimum. Cross references shall be used only to clarify the relationship of requirements within the specification and to avoid inconsistencies and unnecessary repetition. When the cross reference is to a paragraph, subparagraph, etc., within the specification, the cross reference shall be only to the specific paragraph number. The word paragraph shall not appear..

3.2.8 Figures.

A figure is a picture or graph, and constitutes an integral part of the specification. It shall be clearly related to, and consistent with, the text of the associated paragraph. Figures should not be confused with numbered and dated drawings referenced in the text which shall be listed in Section 2 and not physically incorporated in the specification..

3.2.8.1 Location of figures in specification.

Each figure shall be placed following, or within, the paragraph containing a reference to it. If figures are numerous and their location, as indicated above, would interfere with correct sequencing of paragraphs and cause difficulty in understanding or interpretation, they may be placed in numerical sequence at the end of the specification before any appendix or index..

3.2.8.2 Preparation of figures.

All figures shall be titled, and they shall be numbered consecutively with Arabic numerals in the order in which they are initially referenced in the specification..

3.2.9 Tables.

A table is an arrangement of data in lines and columns. It shall be used when data can thus be presented more clearly than text. Elaborate or complicated tables shall be avoided. References in the text shall be sufficiently detailed to make the purpose of the table clear, and the table shall be restricted to data pertinent to the associated text..

3.2.9.1 Location of tables in specifications.

A table shall be placed following, or within, the paragraph containing a reference to it. If space does not permit, a table shall be placed at the beginning of the succeeding page, or if extensive, on a separate page. If tables are numerous and their location, as indicated above, would interfere with correct sequencing of paragraphs and cause difficulty in understanding or interpretation, they may be placed in numerical sequence at the end of the specification before any appendix or index. .

3.2.9.2 Preparation of tables.

The tables shall be numbered consecutively with Roman numerals in the order in which they are initially referenced in the specification. The number and title shall be placed above the table. The contents of a table shall be organized and arranged to show clearly the significance and relationship of the data. Data included in the text shall not be repeated in the table. Tables shall be boxed in and ruled. When a table is of such width as to make it impracticable to place it in normal position on the page, it shall be rotated counterclockwise 90 degrees..

3.2.10 Foldouts.

Foldouts shall be avoided except where required for legibility. Large tables or figures may be broken out so that they may be printed on facing pages. Where foldouts are required, they should be grouped in one place, preferably at the end of the specification (in the same location as figures) and suitable reference to their location shall be included in the text. .

3.2.11 Footnotes.

3.2.11.1 Footnotes to text.

Footnotes to the text shall be avoided if possible. Their purpose is to convey additional information that is not properly a part of the text. A footnote to the text shall be placed at the bottom of the page containing the reference to it..

3.2.11.2 Footnotes to tables and figures.

Footnotes to a table or figure shall be placed below the table or figure. The footnotes may contain mandatory information that cannot be presented as data within a table. Footnotes shall be numbered separately for each table. Where numerals will lead to ambiguity (for example in connection with a chemical formula), superior letters, asterisks, daggers, and other symbols may be used..

3.2.12 Contractual and administrative requirements.

A specification shall not include contractual requirements which are properly a part of the contract; such as cost, time of delivery, instructions on reworking or resubmitting rejected items or lots method of payment, liquidated damages, provision for configuration items damaged or destroyed in tests, etc. Contractual, administrative, and warranty provisions such as those covered in general provisions of contracts, shall not be made part of the requirements in the specification. Contractual and administrative provisions not covered in the general provisions, but considered essential for procurement, may be indicated as 'ordering data' or 'features to be included in bids or in contract' in Section 6. This provision shall be exercised with caution and limited to essential matters. .

3.2.13 Definitions in specifications.

The inclusion of a definition can be avoided if requirements are properly stated. When the meaning of one or more terms must be established in the specification, definitions shall be placed in the text. However, it is often clearer to list one or more definitions in Section 6, especially where the terms are used in many places throughout the specification. When this is done, a parenthetical reference to the applicable paragraph in Section 6 shall follow the terms to indicate the existence of a definition..

3.2.14 References to other documents.

Referencing is the approved method for including requirements in specifications where this eliminates the repetition of requirements and tests that are adequately set forth elsewhere. However, chain referencing should be avoided. References shall be restricted to documents that are specifically and clearly applicable to the specification, and are current and available. Care shall be taken in writing the specification to indicate in a positive manner the extent to which a referenced document is applicable. The specification shall also include any special details called for by the referenced document. Reference to paragraph numbers in other documents shall not be made. The reference shall be to a title, method number, specifically identified requirement, or other definitive designation..

3.2.14.1 Limitation on references.

A specification shall not contain anything in conflict with provisions in referenced documents unless it is desirable to make special exceptions to such provisions, in which case the specific provision to which exception is made shall be stipulated or the application of a specific portion of the referenced document shall be clearly defined. It is not intended that other documents be made a part of a specification by reference unless the items, materials, tests, or other services in the referenced documents are required in the quality and detail which these documents are designed to produce. The applicability of all referenced documents listed in Section 2 of a specification shall be defined in Section 3, 4, or 5, as appropriate. The extent of applicability of referenced documents shall also be specifically indicated. The whole of a referenced document shall not be made applicable by reference unless all of its provisions are clearly required..

3.2.15 Security marking of specifications.

Specifications containing classified information shall be marked and handled in accordance with current security regulations as specified in the DOD 5220.22-M..

3.2.16 Identification of specifications.

Each specification shall be numbered and dated on each page. The identification number, with the date below it shall always appear at the top of the page opposite the binding edge..

3.2.16.1 Identification of Government activity specifications.

This series of specifications shall be identified by the code identification of the Government design agency as listed in Cataloging Handbook H4 and by a number assigned by the Government design agency. Such number may be either a number or a combination of letters, numbers and dashes. The number shall not contain more than fifteen characters, excluding dashes and revision letter. Specifications for HWCIs, materials or processes intended for multiple application may be identified by a military specification number. In such instances, the number shall be applied in accordance with Defense Standardization Manual 4120.3-M and no design agency code identification is used..

3.2.16.2 Identification of contractor specifications.

This series of specifications shall be identified by the manufacturer's code identification of the design contractor as listed in Cataloging Handbook H4 and by a number assigned by the contractor. The assigned number shall not contain more than fifteen characters, excluding dashes and revision letter..

3.2.16.3 Revision symbols.

Revision letters, starting with 'A' for the first revision, and assigned alphabetically for each succeeding revision, shall follow the specification number. Letters, such as I, O, Z, which can be confused with numerals shall not be used. .

3.2.16.4 Identification of two-part specifications.

When a two-part specification concept (See 3.1.4) is used, the parts shall be identified on the title page and both parts shall be assigned the same specification number (See figure 1). Revision status of each part shall be separately maintained..

3.2.16.5 Identification of specification sheet.

The specification sheet is identified by the same number and code identification, as the associated applicable general specification followed by a virgule (slant) and a sequentially assigned Arabic numeral for the sheet. The sheet number shall be assigned by the contracting agency for the general specification and the total number of characters for the specification excluding specification sheet numbers shall not exceed fifteen..

Example: Code Ident 10001 WS 1967B/1A designates revision A of sheet 1 issued for the B revision of general specification, numbered WS 1967..

3.2.16.6 Designation of FSC Code.

If applicable, Federal Supply Classification (FSC) code shall appear in the lower right-hand corner of the first page of the specification. FSC codes shall be as assigned in Cataloging Handbook H2..

3.2.16.7 Titling the specification.

The approved basic name of the material, product or service covered by the specification shall be the first part of the title. Configuration item names in titles shall make maximum use of Cataloging Handbook H6. However, the basic noun in the title shall be in the singular form if the specification covers only one product, and in the plural form if the specification covers more than one product, i.e., various types, grades, classes, sizes or capacities, etc. except where SPECIFICATION NUMBER 12345B CODE IDENT XXXXX.

 PART I OF TWO PARTS.

 (Date).

 PRIME ITEM DEVELOPMENT SPECIFICATION.

 (APPROVED TITLE).

 (TYPE DESIGNATOR, CONFIGURATION ITEM NUMBER, ETC.)

 Example of Identification for Part II.

The only form is plural or where the nature of the product unavoidably requires the plural form. Where there is no approved configuration item name, the title shall be developed in accordance with DOD-STD-100. For general specifications the words 'General Specifications For' shall be the closing phrase of the title..

3.2.16.7.1 Modifiers.

The title of the specification shall include, where appropriate, and in addition to the approved basic name, the minimum number of modifiers, including Type Designators, as are necessary for distinction and ready identification of the coverage of the specification. Nondefinitive modifiers shall not be used. Modifiers shall be arranged in reverse order and separated from each other and the noun name by punctuation. .

3.2.16.7.1 Type of specification.

The type of specification shall be included above the specification title. As a minimum,

the type shall be specified as 'SYSTEM/SUBSYSTEM,' 'DEVELOPMENT,' 'PRODUCT,' 'PROCESS,' or 'MATERIAL.' Subtype may be specified when desired by the contracting agency.

3.3 CHANGES AND REVISIONS.

3.3.1 General.

Specifications shall be corrected or updated when necessary, by means of either a change or revision. A change is accomplished by the issue of a Specification Change

Notice (SCN) and attached change pages. A revision consists of a complete reissue of the entire specification, all pages being identified by the same applicable revision letter. In general, corrections to only a small portion of a specification should be accomplished by a change, whereas extensive corrections requiring revision occur when: (a) over 50 percent of the pages have been, or will be involved in the intended correction plus outstanding SCNs; or (b) a revision is economically more practicable than issue of page changes by SCN. As a general rule, no more than five (5) SCNs shall be issued against a particular revision (or original issue); when the sixth modification or correction is required the outstanding changes should normally be incorporated in a revision of the specification (see 6.2)..

3.3.2 Changes.

Changes to specifications shall be proposed by SCN and issued by SCN. Specification sheets shall be changed by revision only. As required by DOD-STD-480, a separate SCN shall be submitted as an enclosure with an Engineering Change Proposal (ECP) for each specification to be changed. SCNs so submitted will be issued and incorporated only after approval of the ECP and the engineering change ordered. An SCN shall also be used

to issue corrections to a specification unrelated to an ECP (see 6.2)..

3.3.2.1 Specification change notice.

The SCN is a document used to propose, transmit and record changes to a specification. The SCN form (figure 2) is used as a cover sheet and letter of transmittal, the page changes associated with that SCN shall be attached and shall constitute an integral part of the SCN (see 6.2). .

3.3.2.1.1 Proposed SCN.

A proposed SCN shall be used to propose to the specification approving agency the exact change in specification paragraphs, figures or other content that will be distributed to users if the SCN is approved. Such modification in content in this proposed form of the SCN may be submitted in final specification change form or as an enclosure on which the proposed changes in sentences, paragraphs, figures, tables, etc., are described..

3.3.2.1.2 Approved SCN.

An approved SCN, is used to transmit the change after approval by the contracting agency. It also provides a summary of pages affected by all approved changes. SCNs are not cumulative insofar as transmittal of previous changes is concerned, and changes distributed with previous SCNs remain in effect unless changed or canceled by a SCN of later issue. However, the summary of current changes is a cumulative summary as of date of approval of the latest SCN..

3.3.2.2 Changed pages.

Updated and reissued pages shall be complete reprints of pages suitable for incorporation by removal of old pages and insertion of new pages. All portions affected by the change shall be indicated by a symbol in the right hand margin adjacent to, and encompassing all changed portions. When change pages are issued for specifications with pages printed on both sides of a sheet, and only the page on one side of a sheet is affected by the change, both sides of the sheet shall be reissued. The unaffected page side shall be reprinted without change and shall not carry the date of the change or be included in the change summary as being affected by the change..

3.3.2.3 Change numbering.

SCN numbers shall be assigned in sequence, beginning with 1, against the original issue or current revision of a specification. Thus, when a specification is revised, the SCN numbers begin again with 1. The proposed SCN, and approved SCN shall carry the same number. Once an SCN has been submitted to the contracting agency, its SCN sequence number shall not thereafter be changed or assigned to another SCN. However, SCNs may be approved by the contracting agency out of sequence. Hence, an SCN, proposed after a previously proposed but not yet approved SCN, may require revision if the later one is approved prior to the earlier one or an earlier SCN is not approved; in which case the numbers assigned will not change, however, the contents of the change pages may require a change (see 6.2)..

3.3.2.4 Identification and numbering of changed pages.

3.3.2.4.1 Identification.

Each changed page shall be identified by means of the specification number and the applicable revision letter. Under such number shall be entered the date of issue of the SCN, which shall agree with the date entered in the upper right hand corner of the SCN form..

Example: Assume that the current revision of the specification is A, the date of issue of such revision is 20 June 1966, and two SCNs have been approved. If SCN-2 is issued on 5 June 1967, the pages changed by SCN-2 would carry the following identification on each page..

18D4739A.

5 June 1967.

3.3.2.4.2 Page numbers.

The changed pages furnished with an SCN shall be numbered with the same page numbers as the pages they replace. If it is necessary to replace one page with more than one, the additional pages shall carry the same number as the affected page plus a suffix letter in alphabetical order beginning with 'a'. Thus, the numbers of changed pages to change page 5, would be 5, 5a, 5b, etc. If a page is deleted, that number shall be omitted in the current page sequence. .

3.3.3 Revisions.

A revision of a specification is a reissue of a complete specification and shall be prepared, issued, and identified in the same manner as the specification that it supersedes, except that the identification number shall be followed by an appropriate revision letter. Letters shall be assigned in alphabetical order for each succeeding revision. Revision letter 'A' shall be assigned to the first revision. Each revision shall incorporate all outstanding approved changes against the previous issue as well as approved changes proposed by the SCN that creates the need for revision. Revisions of specification will include symbols in the right hand margins of the pages to indicate where changes have been made with respect to the prior issue, including changes. The following note will be included in the Notes, Section 6, of the specifications:.

'The margins of this specification are marked with a (symbol) to indicate where changes (additions, modifications, corrections, deletions) from the previous issue were made. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notation and relationship to the last previous issue.'.

The following note may be used in lieu of the above, if applicable..

'Symbols are not used in this revision to identify changes with respect to the previous issue, due to the extensiveness of the changes.'.

Specification revisions shall be issued in the same manner as the original issue and do not require an SCN for promulgation (see 6.2)..

4.0 GENERAL REQUIREMENTS FOR SECTIONS OF SPECIFICATIONS ^

4.1 Specification 1 - SCOPE.

General information pertaining to the extent of applicability of a configuration item, material or process covered by a given specification and, when necessary, specific detailed classification thereof, shall be placed in the appropriate subdivision of Section 1 of specifications. However, this section shall not contain requirements properly part of other sections of the specification..

4.1.1 Scope.

A statement of the scope shall consist of a clear, concise abstract of the coverage of the specification and may include, where necessary, information as to the use of the configuration item other than specific detailed applications covered under 'Intended use' in Section 6 of the specification. This brief statement shall be sufficiently complete and comprehensive to describe generally the configuration item, material or process covered by the specification in terms that may be easily interpreted by manufacturers, contractors, suppliers, or others familiar with applicable terminology and trade practices. As applicable, reference may be made to information contained in Section 6 of the specification..

4.1.2 Classification.

Where a specification covers

more than one category of a configuration item, designations of classification such as types, grades, classes, etc. shall be listed under this heading and shall be in accordance with accepted industry practice. The same designation shall be used throughout the specification. The name of the configuration item covered by the specification shall be followed by the words 'shall be of the following types, grades, classes, etc., as specified', listing only the applicable designations. When more than one type, grade, class, etc., is listed, each shall be briefly defined. When only one (type, grade or other) is covered, a statement to this effect shall be included in the scope paragraph, and the classification paragraph omitted. The types, grades, classes, etc., shall not change when the specification is changed or revised except when industry practice changes, or for other good reason a change is required. Where the characteristics of a configuration item change enough to affect inter- changeability, the original designation shall be deleted and a new type, grade, class, etc. shall be added. Whenever it becomes necessary to change the designation without changing the characteristics of the configuration item, a cross reference shall be included in Section 6 indicating the relationship between the new and old designations. Since such changes may require cataloging and other record changes, such changes shall be kept to a minimum..

4.1.2.1 Classification definitions.

For the purpose of preparing specifications, 'type,' 'class,' 'grade,' 'composition,' and 'style' are defined as indicated below. However, the actual classification

used in a specific specification will be in accordance with accepted practice as indicated in 4.1.2..

4.1.2.1.1 Type.

This term implies differences in like configuration items or processes as to design, model, shape, etc., and generally will be designated by Roman numerals, thus 'type I,' etc..

4.1.2.1.2 Class.

This term provides additional categorization of differences in characteristics other than afforded by type classification that do not constitute a difference in quality or grade; but are for specific, equally important uses, and generally will be designated by Arabic numerals; thus; 'class 1,' 'class 2,' etc..

4.1.2.1.3 Grade.

This term implies differences in quality of a configuration item and generally will be designated by capital letters; thus 'grade A,' 'grade B,' etc..

4.1.2.1.4 Composition.

This term is used in classifying configuration items that are differentiated strictly by their respective chemical composition, and generally will be designated in accordance with accepted trade practice when satisfactory to the Government design agency..

4.1.2.1.5 Style.

This term is used to denote differences in design or appearance..

4.1.2.1.6 Other classifications.

If the terms `types,' `grades,' and `classes' do not serve accurately to classify the differences as indicated above, other terms such as color, form, weight, size, power supply, temperature rating, condition, unit, enclosure, rating, duty, insulation, kind, variety, etc., suitable for reference, may be used..

4.1.2.2

Classification for reliability level identification. When a specification contains a multilevel reliability requirement, Section 1 of the specification shall identify the levels covered.

4.2 Section 2 - APPLICABLE DOCUMENTS.

All and only those documents referenced in Section 3, 4, 5 and Appendixes of the specification shall be listed in Section 2 of the specification. If numerous, Section 2 may reference an appendix or other appropriate document containing a complete listing. References shall be confined to documents currently available at the time of issuance of the current revision of the specification. Figures bound integrally with the specification shall not be listed in Section 2..

4.2.1 Government documents.

Federal and military specifications (as well as Government design agency specifications), standards, drawings, and other Government publications may be referenced in specifications. Government regulations or codes that are mandatory on the military services (such as: Federal Insecticide, Fungicide, and Rodenticide Act; Drug and Cosmetic Act; Federal Hazardous Substances Labeling Act; Atomic Energy Act; Department of Transportation Regulations; and Screw-Thread Standards for Federal Services) shall be referenced in specifications, where applicable..

4.2.2 Non-Government documents.

Reference may be made to non-Government specifications, standards, and publications promulgated by commercial organizations, technical societies and other non-Governmental agencies when such documents are accepted by the using Governmental agency. Care shall be taken in referencing non-Governmental publications so as to assure the availability of copies and prior approval of the copyright owner..

4.2.3 Listing of references.

References shall be listed by document numbers and titles, and may include specific issue or revision where necessary to rigidly control the configuration or implementation of the configuration item, material or process. The title of each document shall be that appearing on the document itself rather than that shown in an index..

4.2.3.1 Government documents.

Government SPECIFICATIONS STANDARDS, DRAWINGS, and other PUBLICATIONS intended to be made available to bidders shall be listed under the appropriate preceding headings and in alphabetical-numerical order in individual groups, such as Federal, Military, and Departmental agency (such as Weapons Command, etc.).

4.3 Section 3 - REQUIREMENTS.

The essential requirements and descriptions that apply to performance, design, reliability, personnel subsystems, etc. of the configuration item, material or process covered by the specification shall be stated in this section. These requirements and descriptions shall define as applicable, the character or quality of the materials, formula, design, construction, performance, reliability, transportability, and product characteristics, chemical, electrical, and physical requirements, dimensions, weight, color, nameplates, product marking, workmanship, etc. This section is intended to indicate, as definitively as practicable, the minimum requirements that a configuration item, material or process must meet to be acceptable. The Requirements section shall be so written that compliance with all requirements will assure the suitability of the configuration item, material or process for its intended purpose, and non-compliance with any requirement will indicate unsuitability for the intended purpose. Only those requirements shall be specified that are necessary and practicably attainable.

  1. Section 3 of a general specification shall contain all requirements that are common to a family of systems, configurations items, materials or processes. When detail specifications are to be prepared to supplement the general specification to fully define an individual configuration item, etc., the following paragraph shall be included in Section 3 of the general specification:

    3.x.x Detail Specification. Requirements for individual (insert the proper term from among the following) parts, configuration items, materials, process, systems shall be as specified herein and in accordance with the applicable detail specification.

  2. Section 3 of a detail specification shall contain the requirements only for the particular system, configuration item, material or process covered by that specification. However, if the specification does cover more than one type, class, grade, etc., it should first specify the general requirements for all types, classes, grades, etc. The differentiating requirements may then be specified for the individual types, classes, grades, etc., in the proper sequence. In general, each requirement shall be covered in a separate paragraph; and where one requirement differs for the various types, classes, grades, etc., a separate paragraph immediately following the general requirements shall be devoted to each type, class, grade, etc. The various detailed requirements shall be contained in appropriate subparagraphs. Where it is necessary to include additional data, descriptive and appropriate headings shall be used and assigned in logical order.
  3. Section 3 of system or development specifications (Type A or B) shall set forth requirements in terms or performance, reliability, design constraints, functional interfaces, etc., that are necessary to assure a practical and reasonable development effort. Development specifications may include design goals in addition to minimum requirements, but in such case, goals and requirements shall be clearly identified to avoid confusion. Only essential design constraints shall be included as requirements, such as restriction of use of certain materials due to toxicity, dimensional or functional restrictions to assure compatibility with associated equipments, etc.
  4. Section 3 of a product, process or material specification (Type C,D,E) shall contain all requirements necessary to assure delivery of an acceptable end product. Requirements in product function specifications shall include both physical (dimensional and interface characteristics) and performance requirements in sufficient detail to assure procurement of interchangeable, but not necessarily identical HWCIs. Requirements in a product fabrication specification shall include all requirements necessary to assure delivery of identical HWCIs from suppliers. This is normally accomplished by invoking a set of drawings (DOD-D-1000 Level 3) as a primary requirement. Product fabrication specification requirements may also set forth requirements for performance, reliability, workmanship, etc., when such features or characteristics are not completely controlled by detail drawings.

4.3.1 Definition.

Where applicable, a definition of the system or configuration item shall be provided in the form of a brief description, and shall: identify major physical parts, functional areas and functional and physical interfaces; and shall include system logic diagrams, block diagrams, schematic diagrams, and pertinent operational, organizational and logistic considerations and concepts.

4.3.2 Characteristics.

Development, product and material specifications, shall specify all required performance characteristics, physical characteristics, and requirements for reliability, maintainability, environmental consideration, and, as appropriate, relative priority of design disciplines or characteristics.

4.3.2.1

Performance characteristics. These characteristics shall include general and detail requirements, under appropriate sub-headings, for all performance requirements, i.e., what is expected of the system, configuration item, or material.

4.3.2.2 Physical characteristics.

These characteristics in a development, product, or material specification shall set forth requirements such as weight limits, dimensional limits, etc., necessary to assure physical compatibility with other elements and not determined by other design and construction features or referenced drawings. They shall also include considerations such as transportation and storage requirements, security criteria, durability factors, health and safety criteria, command control requirements, and vulnerability factors.

4.3.2.2.1 Protective coating.

Where applicable, protective coating requirements shall be specified under this heading to assure protection from corrosion, abrasion, or other deleterious action. Where feasible, color and protective coating should be combined.

4.3.2.3 Reliability.

Reliability requirements shall be stated numerically with confidence levels, if appropriate, in terms of mission success or hardware mean time between failures. Initially, reliability may be stated as a goal and a lower minimum acceptable requirement. During contract definition, or equivalent period, realistic requirements shall be determined and incorporated in the specification with requirements for demonstration. Reliability requirements shall never be stated as a goal in Type C (product)

specifications.

4.3.2.4 Maintainability.

Numerical maintainability requirements shall be stated in such terms as mean-time-to- repair (MTTR) or maintenance man-hours per flight/operational hour. Determination of realistic requirements shall be made as discussed in 4.3.2.3 for reliability. Qualitative requirements for accessibility, modular construction, test points, and other design requirements may be specified as required.

4.3.2.5 Environmental conditions.

Environments that the system or equipment is expected to experience in shipment, storage, service, and use shall be specified. Where applicable, it shall be specified whether the equipment will be required to meet or be protected against specified environmental conditions. Subparagraphs shall be included as necessary to cover environmental conditions such as: climate, shock, vibration, noise, noxious gases, etc.

4.3.2.6 Transportability.

Any special requirements for transportability and materials handling shall be specified under this heading.

4.3.3 Design and construction.

Minimum or essential requirements that are not controlled by performance characteristics, interface requirements, or referenced documents shall be specified. They shall include appropriate design standards, requirements governing the use or selection of materials, parts and processes, interchangeability requirements, safety requirements, and the like.

4.3.3.1 Materials.

Requirements for materials to be used in the item or service covered by the specification shall be stated under this heading, except where it is more practicable to include the information in other paragraphs. Requirements of a general nature should be first, followed by specific requirements for the material. Definitive documents shall be referenced for the material when such documents cover materials of the required quality.

4.3.3.1.1 Toxic products and formulations.

Specifications requiring or permitting toxic products and formulations shall demand compliance with the requirements of the applicable regulations promulgated by the appropriate Federal regulatory agency or the official compendia governing such products and formulations.

4.3.3.2. Electromagnetic radiation.

Where applicable, requirements pertaining to electromagnetic radiation shall be stated in terms of the environment which the item must accept and the environment which it generates.

4.3.3.3. Nameplates or product markings.

The nameplate or markings in some cases may be the only means of identification of a product after delivery. Such identification is important from the standpoint of stock, replacements, and repair parts. All requirements pertaining to nameplates or markings shall be placed under this, or other appropriate heading, referencing applicable specifications (e.g., MIL-STD-130), drawings, or standards.

4.3.3.4 Workmanship.

Where applicable, reference to workmanship shall be stated and shall include the necessary requirements relative to the standard of workmanship desired, uniformity, freedom from defects, and general appearance of the finished product. This paragraph is intended to indicate as definitively as practicable the standard of workmanship quality that the product must meet to be acceptable. The requirements shall be so worded as to provide a logical basis for rejection in those cases where workmanship is such that the time is unsuitable for the purpose intended. Generally, no definite tests other than visual examination of workmanship will be applicable to the requirements of this paragraph.

4.3.3.5 Interchangeability.

This paragraph shall specify the requirements for the level at which components shall be interchangeable or replaceable. Entries in this paragraph are for the purpose of establishing a condition of design, and are not to define the conditions of interchangeability that are required by the assignment of a part number.

4.3.3.6 Safety.

This paragraph shall specify requirements to preclude or limit hazard to personnel, equipment, or both. To the extent practicable, these requirements shall be imposed by citing established and recognized standards. Limiting safety characteristics peculiar to the item due to hazards in assembly, disassembly, test, transport, storage, operation or maintenance shall be stated when covered neither by standard industrial or service practices nor the system specification. 'Fail-safe' and emergency operating restrictions shall be included when applicable. These shall include interlocks and emergency and standby circuits required to either prevent injury or provide for recovery of the item in the event of failure.

4.3.3.7 Human engineering.

Human engineering requirements for the system/configuration item should be specified herein and applicable documents (e.g., MIL-STD-1472) included by reference. This paragraph should also specify any special or unique requirements, e.g., constraints on allocation or functions to personnel, and communications and personnel/ equipment interactions. Included, should be those specified areas, stations, or equipment that require concentrated human engineering attention due to the sensitivity of the operation or criticality of the task, i.e., those areas where the effects of human error would be particularly serious.

4.3.4 Documentation.

Where applicable, requirements for documenting the design shall be specified in general terms in development specifications. Requirements shall specify types of documents required for design review and approval, manufacture or procurement, testing, inspection installation, operation, maintenance, and logistic support as appropriate. This paragraph is not intended as a requirement for procurement or delivery of data, which shall be accomplished by use of DD Form 1423.

4.3.5 Logistics.

Where applicable, logistic considerations and conditions that will apply to the system or configuration item shall be specified in development specifications and, if applicable, in product specifications. Logistic conditions such as maintenance considerations, modes of transportation, supply system requirements, and impact on existing facilities and equipments shall be considered.

4.3.6 Personnel and training.

Where applicable, requirements imposed by or limited by personnel or training considerations shall be specified in development specifications. Training considerations shall include existing facilities, equipment, special/emergency procedures (associated with hazardous tasks) and training simulators,

as well as the need for additional facilities, equipment, and simulators.

4.3.7 Characteristics of subordinate elements.

Subsequent paragraphs shall be added as necessary to system, development, or product specifications to specify requirements for subordinate elements of the subject system or configuration item. Requirements for each selected subordinate element shall be grouped under a major heading titled with the name of the subordinate element and shall include all of the pertinent types of requirements discussed in previous paragraphs for the parent system or configuration item. Requirements imposed directly on the subelement by a requirement on the parent system or configuration item shall not be repeated. Allocation or apportionment of a parent system (or configuration item) requirement may be specified for the subelement. Subelements may be functionally or physically integrated portions of the parent system (or configuration item), but would not usually be both in a single specification.

4.3.8 Precedence.

A paragraph shall specify the order or precedence of requirements; such as, specification over drawings, functional requirements over physical requirements, adherence to specified processes over other requirements, etc. The paragraph

shall also require that the contractor notify the contracting agency of each instance of conflicting, or apparently conflicting, requirements.

Alternatively, this paragraph may specify that the requirements of the specification shall take precedence over referenced documents. In system or development specifications, this paragraph shall specify the relative importance of requirements (or goals) to be achieved by the design.

4.3.9 Qualification.

Qualification, as used in this Standard, refers to the verification or validation of item performance in a specific application. This qualification results from design review, test data review, and configuration audits. Where performance qualification of a design or an end configuration item (including its components) is required, either on a one-time basis or a periodic basis, to achieve design approval, proof of producibility, assessment of production or other reason, provisions for such qualification testing shall be stated in this paragraph. Requirements shall be included which state the conditions for testing, the time (program phase) of testing, period of testing, number of units to be tested, and other requirements relating to qualification or requalification.

Qualification, as used in Defense Standardization Manual 4120.3-M, refers to the testing or review of test data to judge configuration items from various sources as being suitable for general application, and is intended to lead to the establishment of a Qualified Products List (QPL). Therefore, this type of qualification is subject to the provisions of Manual 4120.3-M and is not within the scope of this Standard.

4.3.10 Standard sample.

A standard sample is one considered essential to supplement or illustrate certain requirements of the specification. Use of standard samples should be kept to a minimum, since their use can create problems in determining the acceptability of HWCIs subsequently produced. Adequate inspection requires that all requirements be made available such as the approved tolerances of dimensions, performance, etc. A standard sample does not provide all this information but must be supported by specification requirements and drawings. The use of the standard sample shall be limited to the illustration of qualities and characteristics that cannot be readily described because detailed test procedures or design data are not available, or because certain qualities and characteristics cannot be definitely expressed, such as the texture of fur, the color of cloth, or the grain of wood. Further, the specification should state the specific characteristics and the degree to which these characteristics are to be observed in the standard sample. When a standard sample is to be furnished, it shall be so stated in Section 3. Means of obtaining or viewing standard samples shall be specified in Section 6.

4.3.11 Preproduction sample, periodic production sample, pilot, or pilot lot.

Where it is essential that a preproduction or periodic production sample, a pilot model, or a pilot lot be tested for design approval prior to or during regular production on a contract or order, the requirements shall be specified in this section under the appropriate paragraph identification.

4.4. Section 4 - QUALITY ASSURANCE PROVISIONS.

For software, this section shall be titled Qualification Requirements and shall specify the qualification requirements, including methods, levels of testing, tools, facilities, test formulas, algorithms, and acceptance tolerance limits required to show that the requirements stated in Section 3 and 5 have been met. The Software Requirements and Interface Requirements Specification Data Item Descriptions

contain further information for specifying qualification requirements (See 6.2). For software embedded in firmware devices, the application of quality assurance provisions or requirements depends on whether the software is designated as a CSCI or part of an HWCI. When the software is designated as a CSCI, Qualification Requirements apply, but when designated as part of an HWCI, Quality Assurance Provisions apply. For hardware, this section shall include all of the examinations and tests (by reference where applicable) to be performed in order to ascertain that the product, material or process to be developed or offered for acceptance conforms to the requirements in Sections 3 and 5 of the specification. Section 4 shall be arranged in an orderly sequence which will indicate clearly which inspections (examinations and tests) apply directly to the process, material, HWCIs, or lots of HWCIs that were developed or produced and which apply to requirements such as evaluation, qualification (See 4.3.9), preproduction sample, pilot model, or pilot lot. The order of presentation of Section 4 material shall, insofar as practicable, follow the order of requirements as presented in Section 3 of the specification, or alternatively in the most logical order of conducting the examinations and tests listed.

4.4.1 General.

Where applicable, the general test and inspection philosophy shall be described with a statement of responsibility for inspection, classification of examinations and tests, sampling, lot formation, and other information pertinent to the quality assurance provisions but not directly associated with a specific test or examination.

4.4.1.1 Responsibility for inspection.

The DOD concept of quality assurance places primary responsibility for quality assurance of delivered products, materials or services on the supplier who is responsible for offering to the contracting agency only those products, materials or services that conform to all specified requirements. In system specifications, however, where assembly of the system/subsystem is at a Government facility or on a Government-owned vessel involving Government-furnished property and personnel, responsibility for the conduct of tests will probably be split between the contracting agency and the contractor. Accordingly, the supplier's responsibility for inspection shall be clearly stated and the contracting agency's role, either as a partner or monitor, shall be specified. A typical statement of responsibility is as follows:

4.1.1 Responsibility for inspection.

Unless otherwise specified in the contract or order, the supplier is responsible for the performance of all inspection requirements as specified herein. Except as otherwise specified, the supplier may utilize his own facilities or any commercial laboratory acceptable to the contracting agency. The contracting agency reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements.

4.4.1.2 Special tests and examinations.

Any special tests and examinations or associated actions required for sampling, lot formation, qualification evaluation, etc., shall be covered under an appropriate heading, for example:

4.1.2 Preproduction sample, pilot model, or pilot run.

When Section 3 specifies a requirement for preproduction sample, pilot model, or pilot run, Section 4 shall include under an appropriate identification, a description of the testing routine, sequence of tests, number of units to be tested, data required, and the criteria for determining conformance to specified requirements.

4.1.2 Qualification provisions.

When the requirements for HWCIs covered in Section 3 contain a qualification provision, the applicable examinations and tests shall be listed under appropriate headings in Section 4.

These inspections shall be specified for initial and higher levels (reliability levels) of qualification including the test methods for continuous testing, and periodic qualification re-evaluation as covered in Section 3 of the specification.

When a tabular form of presentation will provide a better understanding of the correlation between tests of Section 4 and requirements of Section 3, or would clarify the test requirements for acceptance, performance, qualification, preproduction, etc., a tabular presentation similar to that below shall be made.

4.4.2 Quality conformance inspections.

This section shall list all examinations and tests required to verify that all requirements of Section 3 and 5 have been achieved in the HWCI, material, or process offered for acceptance. These examinations, and tests shall include, or reference as appropriate:

  1. Tests and checks of the performance and reliability requirements.
  2. A measurement of comparison of specified physical characteristics.
  3. Verification, with specific criteria, for workmanship.
  4. Test and inspection methods for assuring compliance, including environmental conditions for performance.
  5. Classification of characteristics as critical, major or minor, as defined in MIL-STD-109. When required for reference purposes in reporting inspection results, the characteristics may be numbered. When numbered, numbers shall be in accordance with the following: 1 through 99 - critical characteristics 101 through 199 - major characteristics 201 through 299 - minor characteristics

4.5 Section 5 - PREPARATION FOR DELIVERY.

Detailed preparation for delivery requirements should be covered as far as practicable in four basic categories, as follows.

4.5.3.1 Preservation and packaging.

The requirements for preservation and packaging shall cover cleaning, drying, and preservation methods adequate to prevent deterioration, appropriate protective wrapping, package cushioning, interior containers, and package identification-marking up to but not including, the shipping container. Where no suitable reference is available, step-by-step procedures for preservation and packaging shall be included.

4.5.3.2 Packing.

The requirements for packing shall cover the exterior shipping container, the assembly of configuration items or packages therein, necessary blocking, bracing, cushioning, and weatherproofing.

4.5.3.3 Marking for Shipment.

Normally, marking requirements shall be established by reference to MIL-STD-129. Markings essential to safety and to the protection or identification of the configuration item which are not required by MIL-STD-129, or are required on a 'When specified' basis by that standard, shall be

specified in detail under this heading. In any instance where reference to MIL-STD-129 is not applicable, requirements in detail or by reference to recognized documents shall include: appropriate identification of the product, both on packages and shipping containers; all markings necessary for delivery and for storage, if applicable; all markings required by regulations, statutes, and common carriers; and all markings necessary for safety and safe delivery.

4.6 Section 6 - NOTES.

Section 6 of specifications shall contain information of a general or explanatory nature, and no requirements shall appear therein. It shall contain information, not contractually binding, designed to assist in determining the applicability of the specification and the selection of appropriate type, grade, or class of the configuration item, such as additional supersession data, changes in product designations (grades, class, etc.), standard sample (if required), etc. This section should include the following, as applicable, in the order listed:
