Clothing Insulation and Temperature Ratings for Outdoor Clothing
Property:
Resistance to dry heat transfer (insulation value) provided by clothing systems
Method:
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"
Instrument:
Thermal manikin in an environmental chamber
Specimen number and size:
1 set of garments sized to fit the manikin
Cost:
$600 for 3 replications in a row on one set of garments
Temperature Ratings:
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.
