EN 13537
Encyclopedia
EN 13537 is a European standard designed to standardize the temperature ratings on sleeping bag
s manufactured and/or sold in Europe. As of January 1, 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.
There is a key change to the way sleeping bags are labeled. A European criterion means that all sleeping bag
s adhering to the criterion will have the temperature ratings set by a standard laboratory test. This means that sleeping bags from different manufacturers will all have comparable temperatures.
There is no legal obligation for brands to conform, as the criterion is optional.
"EN 13537:2002 Requirements for Sleeping Bags" is the official European criterion for the classification of sleeping bags. EN13537 applies to all sleeping bags with the exemption of sleeping bags for military use and sleeping bags for extreme temperatures, i.e., comfort range below -25°C. The criterion was published in 2002 and has now been adopted in most European countries, and also used by numerous outdoor companies outside of Europe.
The criterion is used in the following countries: Austria
, Belgium
, Czech Republic
, Denmark
, Finland
, France
, Germany
, Greece
, Hungary
, Iceland
, Ireland
