Resumen The evaporative resistance and thermal insulation of different types of work and protective clothing were determined from measurements made on human subjects and on a thermal manikin. Similar and comparable insulation values were obtained with the 2 methods. The insulation of clothing is influenced by body posture, movements, wind and moisture. During motion, insulation is reduced by 18-35% compared to when a person is seated. Protective suits generally have a high evaporative resistance, which increases heat stress. Some new waterproof fabrics have low evaporative resistance, which increases the wearer's performance ability and thermal comfort in bad weather conditions. New climate indices which account for the thermal properties of clothing, improve the possibilities to predict the thermal impact on humans of different climatic conditions. They also provide a guideline for the establishment of specifications for clothing for different climates and for the selection of adequate clothing for any given set of ambient conditions.
