DR606-24C Sweating manikin Testing System

【Scope of Application】:
During the simulation of heat exchange between a child's body, clothing, and the environment, by analyzing the relationship between physical parameters such as the temperature difference between the skin surface of the warm body dummy and the ambient temperature, and the non-evaporative heat dissipation rate per unit area of the body surface, the clothing thermal resistance can be calculated;
Also, under specified temperature, humidity, and wind speed conditions, when the tested child clothing is worn on a standing or walking sweating warm body dummy, by measuring the power consumption of the dummy or the evaporation rate of the liquid water transferred by the clothing, the clothing's moisture resistance can be tested and calculated;
This truly simulates and comprehensively tests the thermal and moisture comfort performance of children's clothing.
