This document specifies a method for determining the heat transmission through materials or material assemblies used in protective clothing. Materials may then be ranked by comparing heat transfer indices, which provide 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. Working Committee NA 075-05-02 AA "Schutzkleidung gegen Hitze und Feuer" ("Protective clothing against heat and fire") at DIN Standards Committee Personal Protective Equipment (NPS) is responsible for the German participation.
This document replaces DIN EN 367:1992-11 .
