1 Scope
This International Standard specifies methods for estimating the thermal characteristics
(resistance to dry heat loss and evaporative heat loss) in steady-state conditions
for a clothing ensemble based on values for known garments, ensembles and textiles.
It examines the influence of body movement and air penetration on the thermal insulation and water vapour resistance .
This International Standard does not
— deal with other effects of clothing, such as adsorption of water, buffering or tactile
comfort,
— take into account the influence of rain and snow on the thermal characteristics,
— consider special protective clothing (water-cooled suits, ventilated suits, heated
clothing), or
— deal with the separate insulation on different parts of the body and discomfort due
to the asymmetry of a clothing ensemble.
