ASTM F3628
Standard Test Method for Measuring the Cooling Energy Provided By Wicking Liquid Moisture And Evaporating It From Clothing Materials Using A Sweating Hot Plate
This test method characterizes the cooling energy released back to a wearer’s skin, resulting from the wicking and evaporative behavior of clothing materials. The test apparatus is an actively cooled sweating guarded hotplate, operating over three phases for initialization, sweating, and drying. The computed results include drying time and magnitude of cooling energy during sweating and drying phases.
