This International Standard specifies a method for comparing the heat transmission through materials or
material assemblies used in protective clothing. Materials are ranked by calculation of a heat transfer index,
which is an indication of the relative heat transmission under the specified test conditions. The heat transfer
index should not be taken as a measure of the protection time given by the tested materials under actual use
conditions.
