1. SCOPE

1.1 Scope. This design criteria standard provides fire performance requirements and approved specifications for various categories of interior finish materials and furnishings for use on Naval surface ships and submarines.

1.2 Applicability. This design criteria standard applies to materials for bulkhead sheathing, overhead sheathing, furniture, draperies and curtains, deck coverings, insulation and bedding applications. The fire performance requirements of this design criteria standard supersede those contained in the applicable specifications.

1.3 Limitations. Although the development of limits for toxic products of combustion is of major concern, the information generally available is not refined to the degree to allow inclusion of finite limits in this standard at this time. Components and materials not previously approved by the Navy will be evaluated for fire gas toxicity, off-gassing, health hazards, dermal irritation/sensitization, and other pertinent factors as determined by the Naval Technical Authority.

2. APPLICABLE DOCUMENTS

2.1 General. The documents listed in this section are specified in sections 3, 4, or 5 of this standard. This section does not include documents cited in other sections of this standard or recommended for additional information or as examples. While every effort has been made to ensure the completeness of this list, document users are cautioned that they must meet all specified requirements of documents cited in sections 3, 4, or 5 of this standard, whether or not they are listed.

2.2 Government documents.

2.2.1 Specifications, standards, and handbooks. The following specifications, standards, and handbooks form a part of this document to the extent specified herein. Unless otherwise specified, the issues of these documents are those cited in the solicitation or contract.

NOTES:

1/ Maximum test limits are based upon material bonded to a non-combustible substrate.

2/ Maximum test limits are based upon material attached to, or supported by, a non-combustible substrate.

3/ Use with polychloroprene mattress only.

4/ Wherever a flame spread higher than 25 is indicated, the material is acceptable since there is no other acceptable material available with a lower flame spread.

5/ An 8-ounce weight shall be used for materials tested in accordance with ASTM D6413.

6/ Cement test specimen with MIL-A-21016. Permit cement to dry a minimum of 72 hours before conducting fire test.

7/ Materials tested in accordance with method 6411 of FED-STD-501 shall exhibit ignition time no less than 20 seconds. Ignition time is defined as the time in seconds from the initial application of the burners on the sample until the first self-sustaining flame (ignition) is observed issuing from the top surface of the sample.

8/ Materials tested in accordance with 46 CFR 164.009 shall pass all requirements for noncombustibility.

9/ Specimen shall not burn to the 4-inch mark after the first or second ignition.

10/ No wire gauze shall be mounted beneath the specimen and only three (3) specimens cut from the same tile shall be tested. Each of the three (3) specimens shall pass. If any do not pass, the procedure in ASTM D635 which specifies tests in groups of ten (10) specimens (cut from the same tile) shall be followed.

11/ (a) The fire-containment assembly, with attached insulation, shall have withstood the fire endurance test without passage of flame for a time period equal to that for which the classification is desired, and (b) Transmission of heat through the assembly during the fire endurance test period shall not have raised the average temperature on its unexposed surface more than 250 °F (139 °C) above its initial temperature, nor the temperature of any one point on the surface, more than 325 °F (181 °C) above its initial temperature. The test shall be performed in both vertical and horizontal configurations.

12/ Type I shall be tested twice. One with the glass cloth cover facing the heat source, and one with the flexible polyimide foam facing the heat source.

13/ Material shall be tested as received and after five (5) launderings as per AATCC 135 Procedure IIIB in both warp and fill directions.

14/ Test at maximum thickness contemplated for use.

15/ Where test methods are non-standard, but are called out from within the specification or an Appendix to that specification, the test methods will be referenced as such.

16/ Only molten and/or flaming drops requirement applies to tape. Only initial flammability requirements apply to pocketing material.

17/ The A-A-55188 limits the use of blankets to wool material only. The fire performance requirements apply to alternative materials which are subject to approval by Naval Technical Authority.

18/ When materials are not identical on both sides, each side shall be tested as a different specimen (does not apply to cushioning).

19/ This means no flaming droplets or flaming material which fall from the test mattress during the fire test, shall continue flaming after reaching the test platform or floor.

20/ Where test method ASTM E662 is invoked, tests shall be conducted in both non-flaming and flaming modes.

5.2 Fire test provisions.

5.2.1 Responsibility for testing. Unless otherwise required in the applicable material specification, the manufacturer is responsible for conducting fire tests as specified herein. All tests specified in this document shall be conducted by an independent testing laboratory that is accredited to ISO/IEC 17025 or equivalent procedure.

Accreditation shall be obtained from a recognized accreditation body such as American Association for Laboratory Accreditation (A2LA) or International Code Council’s International Accreditation Services (IAS). The scope of accreditation shall include specific flammability and fire tests required for qualification. The Government reserves the right to witness the tests, and/or perform any of the tests set forth herein where such testing is deemed necessary to assure compliance to prescribed requirements.

5.2.2 Methods of testing. Fire tests shall be conducted on materials as specified in Table I and the notes therein. All fire test procedures shall be in accordance with prescribed standards and test methods and, unless otherwise specified herein, no less than three specimens shall be tested on material of the same lot with results averaged (arithmetic means). Tests as listed in Table II shall apply.
