Protective clothing against heat and flame - Part 2: Skin burn injury prediction - Calculation requirements and test cases (ISO 13506-2:2024)
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.

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.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
The purpose of heat and flame-resistant protective clothing is to shield the wearer from hazards that
can cause skin burn injury. The clothing can be made from one or more materials, which can be made
into a garment or protective clothing ensemble for testing on a manikin fire exposure system.
This document is a companion document to ISO 13506-1. The data gathered by tests according to
ISO 13506-1 are used as input for this calculation.
In the test method standard ISO 13506-1, a stationary, upright, adult-sized manikin is dressed in
a garment or protective clothing ensemble and exposed to a laboratory simulation of a fire with
controlled heat flux, duration and flame distribution. The average incident heat flux to the exterior of
the garment is 84 kW/m . Thermal energy sensors are fitted to the surface of the manikin. The output
from the sensors is used to calculate the heat flux variation with time and location on the manikin and
to determine the total energy absorbed over the data-gathering period. The data-gathering period is
selected to ensure that the total energy transferred will no longer be rising. The information obtained
from the calculation of skin burn injury predicti
