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 “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" ANSI/ISEA 201 "Classification of Insulating Apparel Used in Cold Work Environments"
Thermal manikin in an environmental chamber
Specimen number and size:
1 set of garments sized to fit the manikin
$600 for 3 replications in a row on one set of garments
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.
