CLOTHING EVAPORATIVE RESISTANCE MEASUREMENT USING THERMAL MANIKINS

conference paper

English

Heat transfer from human body through convection, radiation or mainly through sweat evaporation from skin is often restricted when protective clothing is used, which may result in human´s body overheating in certain cases. Thus, it is important to include this into heat strain or physiological predictive models as input data in form of clothing parameters. Purpose of this predictive models is to protect human´s health and to predict a maximum exposure time while using protective clothing. One of the most important clothing parameters is evaporative resistance, which characterize the ability of clothing ensembles to allow vapour to go through itself. This also indirectly defines the level of sweat evaporation restriction from the skin. The main advantage of measuring evaporative resistance by means of thermal manikins is that it takes into consideration the shape of a human body and thus also air layers in measured clothing. There are following things presented in this article - the methodology of evaporative resistance measurement on dry manikin using pre-wetted skin and its application on one clothing ensemble.
