Although I heard a lot of friends say that the temperature standard of the sleeping bag is good, don't believe it. It has also been said that adding another 3 or 5 degrees to the temperature scale will ensure your sleep. I also heard a lot of friends say that the temperature scale is not allowed, don't believe it. But I think, I am afraid that the concept of temperature scale is not very clear. Moreover, in some product descriptions of sleeping bags, you sometimes see a temperature scale, sometimes 2, and suddenly see another brand labeled 3 temperature scales one day. What is more depressing is that someone tells you that there are still 4 A temperature scale, is it a little dizzy?
You don't know what these temperature scales are, then I will explain to you today the interpretation of the international standard temperature measurement method "EN13537" for temperature scales. Nowadays, whether it is TNF or MHW or supermarket type Decathlon, everyone uses the EN13537 sleeping bag temperature standard. So, let me explain what this standard explains for the four temperature scale data given after the sleeping bag is tested:
MAXIMUM (highest temperature standard): The upper limit of the comfort range of high temperature is to measure the standard healthy male in the standard test environment. The body part does not cover the sleeping bag during sleep, and there is not too much sweat.
COMFORT (Comfort Temperature): measures the standard healthy woman in a relaxed state in a standard test environment, does not feel cold (worry), and maintains physical comfort throughout the night.
LIMIT (Standard Temperature): Measures the standard healthy male who is curled up in a sleeping bag in a standard test environment, does not tremble, and maintains physical comfort throughout the night.
EXTREME: The standard healthy woman is measured in a standard test environment and is exposed to severe cold weather (whole body shake). At this time, there is a threat of hypothermia and even death. The limit temperature is a theoretical range and is only considered as a dangerous critical point that is difficult to achieve.
