This document provides technical details for calculating predicted burn injury to human skin when its
surface is subject to a varying heat flux, such as may occur due to energy transmitted through and by a
garment or protective clothing ensemble exposed to flames. A series of test cases are provided against
which the burn injury prediction calculation method is verified. It also contains requirements for the
in situ calibration of the thermal energy sensor — skin injury prediction system for the range of heat
fluxes that occur under garments.
The skin burn injury calculation methods as presented in this test method do not include terms for
handling short wavelength radiation that may penetrate the skin. The latter include arc flashes, some
types of fire exposures with liquid or solid fuels, and nuclear sources.
