A study was made of the action of cloth in protecting skin from thermal injury resulting from exposure to high-intensity thermal radiation. Methods were developed to obtain temperature-time-depth data for a system simulating skin covered by a layer of dry or moist cloth. Experimentally this was accomplished by the use of a copper-air simulant which accepts heat at the same rate as human skin but develops a proportionally stretched temperature profile. The method facilitates the inspection of the influences on temperature distribution in the skin of various system properties and the surrounding conditions. The skin enthalpy rise above a critical temperature level, a feasible basis for correlating burn data, was found to be very sensitive to slight variations in the temperature response and deserves further testing.
