BS EN ISO 6942:2022 Protective clothing. Protection against heat and fire. Method of test: Evaluation of materials and material assemblies when exposed to a source of radiant heat
1 Scope
This document specifies two complementary methods (method A and method B) for determining
the behaviour of materials for heat protective clothing subjected to heat radiation.
These tests are carried out on representative single or multi-layer textiles or other
materials intended for clothing for protection against heat. They are also applicable
to assemblies, which correspond to the overall build up of a heat protective clothing
assembly with or without underclothing,
Method A serves for visual assessment of any changes in the material after the action
of heat radiation. With method B the protective effect of the materials is determined.
The materials may be tested either by both methods or only by one of them.
The tests according to these two methods 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 taken into account.
Since the tests are carried out at room temperature the results do not necessarily
correspond to the behaviour of the materials at higher ambient temperatures and therefore
are only to a limited extent suitable for predicting the performance of the protective
clothing made from the materials under test.
