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/FDIS 15831 draft standard “Clothing – Physiological Effects – Measurement of Thermal Insulation by Means of a Thermal Manikin"

Instrument:
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 “large” size garments

Cost:
$550 for three replications in a row on one set of garments; $650 for three independent reps on different garment samples

Note: We will charge you for one rep of the nude dry manikin test also ($182).

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.
