Protective clothing against heat and flame — Part 2: Skin burn injury prediction — Calculation requirements and test cases

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.

Habillement de protection contre la chaleur et les flammes — Partie 2: Prédiction de blessure par brûlure de la peau — Exigences de calculs et cas d'essai

Le présent document fournit des détails techniques permettant de calculer la prédiction de blessure par brûlure de la peau humaine lorsque sa surface est soumise à un flux de chaleur variable, par exemple en raison de l'énergie transmise à travers et par un vêtement ou un ensemble de vêtements de protection exposés aux flammes. Une série de cas d'essai est présentée, permettant de vérifier la méthode de calcul de la prédiction des blessures par brûlure. Il contient également des exigences pour l'étalonnage in situ du capteur d'énergie thermique — système de prédiction des lésions cutanées pour la gamme de flux de chaleur qui se produisent sous les vêtements. Les méthodes de calcul des blessures par brûlure de la peau telles qu'elles sont présentées dans la présente méthode d'essai ne comprennent pas de termes permettant de traiter les rayonnements de courte longueur d'onde susceptibles de pénétrer la peau. Ces derniers comprennent les arcs électriques, certains types d'exposition au feu avec des combustibles liquides ou solides, et les sources nucléaires.
