适用范围

1.1 This test method covers the evaluation of heat transfer of textile materials which are used as thermal barriers when exposed to a calibrated convective and radiant energy heat source for 60 seconds.

1.1.1 This standard is used to determine if the heat transfer is sufficient to ignite flammable materials which are contiguous to the textile thermal barriers.

1.2 This standard is used as a means to differentiate textile materials.

1.3 This test method is not intended to measure the insulation properties of materials used in protective clothing.

1.4 The values stated in either acceptable metric units or in other units shall be regarded separately as standard. The values expressed in each system must be used independently of each other, without combining values in any way.

1.5 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.

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.
