Thelma Test

All our sleeping bags are tested to the N13537 standards. This test is the official European Standard for the labelling of sleeping bags. It is a complete product standard which defines how to test, measure and label a sleeping bag. The EN13537 applies to all sleeping bags with the exception of sleeping bags for military use and sleeping bags for extreme temperatures.

The test uses a thermal manikin shaped like the body, but computer controlled, to create a standard for all sleeping bags at various levels of performance. Once placed inside a climatic chamber the manikin is put inside the sleeping bag and the specific therman insulation of the bag can be measured to a series of specific tests creating the following sets of results: Tcomfort,Tlimit, Textreme and Tmax.

• Tmax: Upper limit of comfort range. The temperature up to which a partially uncovered sleeping bag user (standard man) just does not perspire too much.
• Tcomfort: Lower limit of the comfort range down to which a sleeping bag user with a relaxed posture such as lying on the back is globally in equilibrium an just not feeling cold (related to standard woman and in standard condition of use).
• Tlimit: Lower limit of which a sleeping bag user with curled-up body posture is globally in thermal equilibrium and just not feeling cold (related to standard man and in standard condition of use).
• Textreme: Lower extreme temperature where the risk of health damage from hypothermia occurs (related to standard woman and in standard conditions of use).
