ASTM F2700
Standard Test Method for Unsteady-State Heat Transfer Evaluation of Flame Resistant Materials for Clothing with Continuous Heating
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. The test standard 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.
