AI Overview
ASTM F1868-02 is a standard test method used to measure the thermal and evaporative resistance of clothing materials—including fabrics, films, coatings, and leather—under steady-state conditions using a sweating guarded hot plate. It determines how well materials insulate and allow moisture vapor to escape, simulating human skin to assess comfort and protective performance.
