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

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.
