1.4 Test principle: Clothing is often made of materials that are designed to enhance the pickup and distribution of liquids (wicking) to promote the evaporation of sweat. Higher amounts of evaporation should lead to more cooling of the body during active work and less of a chilling effect after active work has stopped. This is important to individuals wearing PPE or athletic wear to enhance comfort and prevent overheating while working. Therefore, it is important to isolate and quantify the amount of cooling provided by a clothing material’s ability to distribute and evaporate liquid away from a heated surface. Just as important, it’s also important to isolate and quantify the amount of cooling provided and the amount of time it takes to remove all the liquid after it is no longer being delivered to the surface.
