EN 13537 (or EN13537) is a European standard designed to standardize the temperature ratings on sleeping bags manufactured and/or sold in Europe. As of 1 January 2005 a CEN criterion came into effect covering the testing and publication of temperature ratings for sleeping bags. The new criterion differs from the standards that existed formerly.
So that practical clothing may be described conveniently by a range of small integers, the unit of thermal resistance, to be called the “tog”, is the resistance that will maintain a temperature difference of 0.1°C. with a flux of 1 watt per square metre, or in more practical terms, 10°C. with a flux of 1 watt per square decimetre.
A tourist in a sleeping bag. A sleeping bag is an insulated covering for a person, essentially a lightweight quilt that can be closed with a zipper or similar means to form a tube, which functions as lightweight, portable bedding in situations where a person is sleeping outdoors (e.g. when camping, hiking, hill walking or climbing).

Calculations based on fill power and loft are only approximate. The warmth of sleeping bags may be more accurately compared using European Norm temperature ratings that are based on realistic independent laboratory tests. The rated temperature (in degrees Celsius) is the lowest comfortable temperature.
