Why EN13537 For Sleeping Bags Temperature Rating ?

Like if this Guide is helpful

EN13537 is the European Criterion for sleeping bags...

Why EPE Global use EN 13537, which is European Standard?

Until now there has been little to no consistency in the way manufacturers have temperature rated sleeping bags in Australia. After searching the world to see how other countries handle this EPE has decided to start applying the European Norm (EN 13537) to the sleeping bags.

The standard measures four temperature ratings

EN 13537 requires a thermal manikin test which produces four temperature results:

Upper Limit a standard man can sleep without excessive perspiration;

Comfort a standard woman can expect to sleep comfortably in a relaxed position;

Lower Limit a standard man can sleep for eight hours in a curled position without waking;

Extreme a standard woman can remain for six hours without risk of death from hypothermia

Which temperature rating to use?

People are use to choosing sleeping bags from a single temperature rating so EPE has decided to use the Lower Limit as identifying temperature.
