This test method rates textile materials for thermal resistance and insulation when exposed to a convective energy level of about 2.0 cal/cm2 (8.3 W/cm2) for a short duration. It is applicable to woven fabrics, knit fabrics, battings and nonwoven fabrics intended for use as clothing for protection against a chance, short exposure to open flames. it is not intended for evaluating materiais exposed to any other thermal exposure such as radiant energy or molten metal splash. This method is a useful research and develop ment tool.

This test method is not applicable to textile materials that undergo complete flaming combustion when tested vertically for flame resistance.

This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all the factors which are pertinent to an assessment of the fire hazard of a particular end use.

This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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. See Section 7.
