Protection against heat - Radiant heat and TPP
Samples are exposed to radiant heat or flame (TPP) for i) a defined temperature increase or ii) a defined duration of time. Temperature is recorded using a copper calorimeter situated on the technical rear of the fabric. The temperature reached or the duration of time taken are used to determine protective capacity of the textile or combination of textiles.
Protective clothing -- Protection against heat and fire -- Method of test: Evaluation of materials and material assemblies when exposed to a source of radiant heat
Protective clothing against heat and flame -- Determination of heat transmission on exposure to flame.
