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 method was developed to quantify the cooling energy actually felt by the wearer of a garment that is partially saturated with moisture. The actual cooling effect of a garment is impacted by multiple factors including wicking and drying properties, fabric construction thermal and evaporative resistance, and environmental conditions.
Using a Dynamic Hotplate with the ability to measure rapid transient response, a fabric sample is exposed to a simulated sweating phase followed by a drying phase. The resulting measurements include drying time and efficiency of evaporation as compared to the maximum possible evaporative cooling energy.
