This test method provides a means for evaluation of the flammable performance of surface finish materials used in constructing and outfitting ships.

A specimen of the surface finish of concern is mounted on the support material contemplated for use and subjected to a controlled significant radiant-flux exposure.

All specimens are tested while mounted in a vertical plane.

The following surfaces are exposed to test:

Bulkhead specimens having surface veneers, fabrics, or painted finishes are tested on one or both exposed sides.

Ceiling finish materials shall be tested on the lower exposed surface.

For ceiling finish materials which are perforated and air backed, tests also shall be conducted on the back (upper) surface of the material.

Deck finish and flooring materials are tested on the upper exposed surface.

Protective membranes or finishes on insulation materials are tested on the air-exposed face or faces.

This test method provides fire properties that relate to the flammability of the specimens tested. These include ignitability, heat exposure for continued burning, critical flux at extinguishment, and heat-release behavior under varying flux-exposure conditions applied.

This test method does not provide:

Full information on fire properties of surface-finish materials supported by backing materials other than those tested.

Full information on surface-finish materials when used in other thicknesses than those tested.

Methods for using the fire property measurements as a measure for classifying the fire risk or hazard of the specimens tested.

1.1 This fire-test-response standard covers a procedure for measuring fire properties associated with flammable behavior of surface finishes used on noncombustible substrates aboard ship (Note 1). In particular, these include surface finishes intended for use in ship construction such as deck surfacing materials, bulkhead and ceiling veneers including any adhesives used to fasten the veneers to the bulkheads and ceilings, paints, and exposed treatment of insulating materials.

Note 1—This test method has been prepared to closely follow the test procedure of IMO Resolution A.653(16) (1). Optional provisions not applicable to the domestic use of this test method have been deleted.

1.2 Tests performed according to this test method are intended to yield fire properties that, when appropriately interpreted, are potentially useful to select materials and surface treatments that will limit the rapid growth and spread of fire.

1.3 This test method requires a specific range of specimen radiant thermal exposure for measuring fire properties.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.

1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 7.
