Protective clothing for firefighters - Physiological impact - Part 1: Measurement of coupled heat and moisture transfer with the sweating torso (ISO 18640-1:2018)

This document provides a test method for evaluating the physiological impact of protective fabric ensembles and potentially protective clothing ensembles in a series of simulated activities (phases) under defined ambient conditions. This standard test method characterizes the essential properties of fabric assemblies of a representative garment or clothing ensemble for thermo-physiological assessment: — dry thermal insulation; — cooling properties during average metabolic activity and moisture management (dry and wet heat transfer); — drying behaviour. Default measurements are done on fabric samples representing the garment or protective clothing combination. Optionally and in addition to the standard test method, the same testing protocol can be applied to characterise more complex protective clothing ensembles including underwear, air layer and certain design features[1]. In addition, measurements on readymade garments are possible. This test method is intended to be used to measure and describe the behaviour of fabric assemblies of a garment or clothing ensemble in response
