ISO 9151:2016
Protective clothing against heat and flame — Determination of heat transmission on exposure to flame
ISO 9151:2016 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.
