1.1 This test method measures the non-steady state heat transfer through flame resistant materials for clothing subjected to a continuous, combined convective and radiant heat exposure.

1.1.1 This test method is not applicable to materials that are not flame resistant.

The determination of a materials flame resistance shall be made prior to testing and done according to the applicable performance and/or specification standard for the materials end-use.

1.1.2 This test method does not predict a materials skin burn injury performance from the specified thermal energy exposure. It does not account for the thermal energy contained in the test specimen after the exposure has ceased.

See Appendix X4 for additional information regarding this test method and predicted skin burn injury.

1.2 This test method is used to measure and describe the response of materials, products, or assemblies to heat 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.

1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound or other units that are commonly used for thermal testing.

1.4 This standard does not purport to address 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.
