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.

5 Measurement and test methods
5.1 Principle
The components of the clothing ensemble to be tested are placed on the manikin in the same
arrangement as in practical use.
The manikin in the shape and size of an adult human body and, for the measurement of R , with
etr,M
movable legs and arms, is internally heated to a constant surface temperature, uniform over its body.
