Test method for thermal protection performance of protective clothing
1 Scope
This standard specifies the thermal protection performance value (hereinafter referred to as "TPP") and thermal protection performance evaluation (hereinafter referred to as
"TPE") test method, including principles, health and safety of laboratory personnel, equipment and materials, preparation and conditioning of samples, calibration and
Maintenance, test procedures, calculation of results, etc.
This standard is applicable to the thermal protection performance test of single-layer or multi-layer materials, and is applicable to the practitioners exposed to the convection and radiation heat hazards.
Evaluation of thermal protection materials.
This standard is not applicable to the testing of non-flame retardant materials that are easy to melt and drip at high temperatures.
