Abstract : Tolerance for all hot environments cannot be defined by a single criterion. At least three types of tolerance are discussed which might occur in aerospace activities. The tolerance categories have been designated (1) pain limited, (2) heat storage limited and (3) systems limited. Pain limited exposures are of short duration and require very high temperatures. Heat storage limited exposures may last from minutes to hours and require high temperatures and low humidities. Systems limited exposures are of intermediate duration and require moderately high temperatures and high humidities. (Author)
