EN 13537 Thermal Requirements for Sleeping Bags

Property:
Resistance to dry heat transfer (insulation value) provided by sleeping bags

Method:
EN 13537 "Requirements for Sleeping Bags”

Instrument:
Thermal manikin on an elevated board in an environmental chamber; bag is tested with standard thermal underwear and socks, a face mask, and a 1 ½ in. self-inflating pad

Specimen number and size:
1 or 3 sleeping bags

Cost:
$550 for three reps in a row on one sample; $650 for 3 independent reps on different samples of the same type

Temperature Ratings:
The comfort, limit, and extreme temperatures will be determined using the heat loss models in the standard; no additional charge for these calculations.

Note: The maximum temperature for comfort requires a second manikin test and temperature prediction. This is optional in the standard and we do not do it.
