GB/T 38302-2025

This document describes the test methods for the thermal protection performance of protective clothing materials (including thermal protection performance values and thermal protection performance evaluation) and the test method for evaluating the flame-retardant performance of clothing under flame engulfment conditions using a manikin. In this document, the thermal protection performance value (TPP) and thermal protection performance evaluation (TPE) tests are applicable to the thermal protection performance testing of single-layer or multi-layer materials, and are used to evaluate the thermal protection materials of workers exposed to convective and radiant heat hazards. The test method for evaluating the flame-retardant performance of clothing under flame engulfment conditions is applicable to the testing and evaluation of the flame-retardant performance of finished protective clothing. This document is not applicable to the testing of non-flame-retardant materials and clothing that are prone to melting and dripping when exposed to high temperatures.
