Sweating Guarded Hotplate Moisture Vapour Resistance
topic
The sweating guarded hotplate (Ret) measures resistance to water vapour transmission by supplying liquid water through a porous sintered plate surface at skin temperature, quantifying evaporative heat flux through the fabric assembly under defined temperature, humidity, and air velocity conditions.
Role
Defines breathability as a thermal comfort parameter for sportswear, protective workwear, and military garments, enabling quantitative comparison of membrane, coating, and weave structure contributions to evaporative cooling efficiency.
