The Hohenstein Institute is located a few kilometers north of Stuttgart. The Institute is a well-recognized interdisciplinary research facility. They’re also actively involved in the testing of textiles – testing and measuring the efficacy of these materials for specific applications.
In a press release dated March 15, 2011 titled ” Even Soldiers Have To Sleep: Thermophysiological Properties of Sleeping Bags” they address the European standard EN 13537; commenting on its applicability and potential adaptability to military applications.
The authors make a number of statements to the effect that users of sleeping systems should know the operating temperature range, which seems fairly obvious.
They also comment on the anthopometric differences between the average camper and a soldier operating in the field.
I think the point being made is that current standards, EN 13537 and EN 15537, do not fairly represent military requirements. However, in their view, the standard can be expanded or modified to take into consideration the physical and physiological differences between commercial and military use.
