The EN13537 standard provides three temperature levels to guide a consumer in their choice.
Comfort: The temperature at which a standard woman can expect to sleep comfortably in a relaxed position. Lower Limit: The temperature at which a standard man can sleep for eight hours in a curled position without waking.The EN13537 temperature tests use a thermal manikin with heaters and temperature sensors to measure the insulation value of a sleeping bag. This manikin is wearing one layer of long underwear and is placed inside the sleeping bag on an insulating mat. The test is conducted in a temperature controlled chamber and a range of comfort temperatures are derived from measuring the energy required to maintain homeostasis in the manikin to a set temperature.
