Title Thermal characteristics of clothing ensembles for use in heat stress analysis
Bibliographic information Jan./Feb. 1999, Vol.60, No.1, p.32-37. 13 ref.
Abstract The thermal characteristics of a variety of protective clothing ensembles were determined for application in the International Organization for Standardization (ISO) standard for required sweat rate, used for the assessment of occupational heat stress. Experiments were carried out using five subjects in four environmental conditions for each ensemble. Metabolic rate, average skin temperature and the environmental conditions were noted at the critical conditions in which subjects were just able to maintain thermal equilibrium. The total insulation was estimated for each ensemble. From these values, the total evaporative resistance and the clothing factors for dry heat exchange and for evaporative cooling were determined. It is suggested that these clothing coefficients can be used in the ISO standard for these clothing ensembles and thus increase the utility of the standard. Topics: comment on standard; energy metabolism; heat load; heat transfer; microclimate; protective clothing; skin temperature; sweat rate.
