1.1 These test methods described in this fire-test response standard are used for determining the fire-test response of insulated marine steel bulkheads and decks. The insulation is either homogeneous or composite construction.

1.2 It is the intent that tests conducted in accordance with these test methods will indicate whether bulkheads and decks will continue to perform their intended function during the period of fire exposure. These test methods shall not be construed as implying suitability for use after fire exposure.

1.3 These test methods prescribe a standard fire exposure for comparing the relative performance of different bulkhead and deck assemblies under controlled laboratory conditions. The application of these test results to predict the performance of actual assemblies when exposed to large pool fires requires a careful engineering evaluation.

1.4 Limitations—These test methods do not provide the following:

1.4.1 Full information on the performance of assemblies constructed with components or of dimensions other than those tested.

1.4.2 An evaluation of the degree to which the assembly contributes to the fire hazard through the generation of smoke, toxic gases, or other products of combustion.

1.4.3 Measurement of flame spread over the surface of the test assembly.

1.4.4 The erosive effect that the velocities or turbulence, or both, generated in large pool fires has on some fire protection materials.

1.4.5 Full information on the performance of assemblies at times less than 5 min because the rise time called out in Section is longer than that of a real fire.

1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for approximate information only.

1.6 This standard measures and describes 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.

1.7 This test method is based on the fire exposure as defined in Test Methods E 1529 (issued by the Committee on Fire Standards, E05).

1.8 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.
