Clothing - Physiological effects - Measurement of water vapour resistance by means of a sweating manikin
This document specifies the requirements of the sweating manikin and the test procedure used to measure the water vapour resistance of a clothing ensemble, as it becomes effective for the wearer in practical use in a defined environment, with the wearer either standing or moving. This water vapour resistance, among other parameters, can be used to determine the effect of clothing on the physiology of the wearer in specific climate/activity scenarios.

Le présent document spécifie les exigences applicables au mannequin transpirant et le mode opératoire d’essai utilisé pour mesurer la résistance à la vapeur d’eau d’un ensemble de vêtements, au moment où il devient efficace pour la personne qui le porte dans la pratique, dans un environnement défini, que cette personne soit immobile ou en mouvement. Cette résistance à la vapeur d’eau, entre autres paramètres, peut être utilisée pour déterminer l’effet du vêtement sur la physiologie de la personne qui le porte dans des scénarios de climat/d’activités spécifiques.

Introduction
The type of clothing worn by people directly affects the heat exchange between the human body and the
environment. The heat transfer is both sensible (conduction, convection, and radiation) and latent
(evaporation). The water vapour resistance of a clothing ensemble is dependent upon the designs and
materials used in the component garments, the amount of body surface area covered by the clothing,
the distribution of the layers over the body, looseness or tightness of fit, and the increased surface area
for heat loss. Water vapour resistance measurements made on fabrics alone do not take these factors
into account. Measurements of the resistance to evaporative heat loss provided by clothing can be used
with thermal insulation values (EN ISO 15831) to determine the comfort or stress of people in different
environments.
1 Scope
This document specifies the requirements of the sweating manikin and the test procedure used to
measure the water vapour resistance of a clothing ensemble, as it becomes effective for the wearer in
practical use in a defined environment, with the wearer either standing or moving. This water vapour
resistance, among other parameters, can be used to determine the effect of clothing on the physiology of
the wearer in specific climate/activity scenarios.

etr,M
movable legs and arms, is internally heated to a constant surface temperature, uniform over its body.
