ASTM F2732
Standard Practice for Determining the Temperature Ratings for Cold Weather Protective Clothing
This standard practice covers the determination of the temperature rating of cold weather protective clothing ensembles. It involves measuring the thermal resistance (insulation) value of a clothing ensemble with a heated manikin in accordance with Test Method F1291 and using a heat loss model to predict the lowest environmental temperature for comfort. The predictive model used in this standard estimates the evaporative heat loss from a person wearing cold weather clothing as opposed to measuring the evaporative resistance on a sweating manikin.
