Clothing Insulation and Temperature Ratings for Outdoor Clothing
Resistance to dry heat transfer (insulation value) provided by clothing systems
ASTM F 1291 "Standard Test Method for Measuring the Thermal Insulation of Clothing
Using a Heated Manikin"
ISO 15831 standard “Clothing – Physiological Effects – Measurement of Thermal Insulation by Means of a Thermal Manikin"
ASTM F 2732 "Standard Practice for Determining the Temperature Ratings of Cold Weather Clothing"
Thermal manikin in an environmental chamber; test can be done with the manikin moving, standing, or sitting
Specimen number and size:
1 or 3 sets of garments sized to fit the manikin
$550 for 3 replications in a row on one set of garments;
$650 for replications on 3 garment samples of the same type
Heat transfer models are used with the insulation value to determine the temperature ratings for comfort at different activity levels. No additional charge for these calculations.
