Description

ASTM F3538 – Standard Test Method for Measuring Heat Transmission Through Flame-Resistant Materials for Clothing in Flame Exposure Using a Cylindrical Specimen Holder

1.1”This test method measures the thermal response of a material or combination of materials using a combined convective/radiant heat transmission apparatus consisting of an eccentric cylindrical test sensor. It can be used to estimate the non-steady state thermal transfer through flame-resistant materials used in clothing when subjected to a continuous, combined convective and radiant heat exposure. The average incident heat flux is 84 kW/m² (2 cal/cm²”s), with durations up to 30 s.

1.1.1”This test method is not applicable to materials that melt, drip, or cause falling debris during the test.

Note 1:”Because of the arrangement of the equipment, if materials melt, drip, or cause falling debris during the test, the test result is invalid.
