This European 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 protection 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.
