EN 13537 Thermal Requirements for Sleeping Bags

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

EN 13537 "Requirements for Sleeping Bags”


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 regular or long sleeping bag 


$600 for 3 replications in a row on one bag sample

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 (see photograph below) and temperature prediction for $600. This is optional in the standard.
