Ergonomics of the thermal environment - Estimation of the thermal insulation and evaporative resistance of a clothing ensemble
Gives 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. Does not deal with other effects of clothing, such as adsorption of water, buffering, tactile comfort. Does not take into account the influence of rain and snow on the thermal characteristics. Does not consider special protective clothing. Does not deal with the separate insulation on different parts of the body and discomfort due to the asymmetry of a clothing ensemble.
