scope:

Specifies two complementary methods (A and B) for determining the behaviour of materials used for protective clothing subjected to radiant heat. These tests are performed on representative single or multi-layer textiles or other materials intended for the manufacture of clothing for protection against heat. They may also be used for material assemblies, which correspond to the overall composition of a protective garment assembly, with or without undergarments. Method A serves to visually assess any changes in the material after exposure to radiant heat. Method B serves to determine the protective effect of the materials. Either one or both methods may be used. The tests specified here serve to classify materials. However, to be able to make a statement or prediction as to the suitability of a material for protective clothing, additional criteria must be considered. Since the tests are carried out at ambient temperature the results do not necessarily reflect the behaviour of the materials at higher temperatures and therefore are only to a limited extent suitable for predicting the performance of the protective clothing made from materials under test.
