Are your sleeping bags tested to determine a temperature rating?

Sea to Summit bags (like most quality sleeping bags) are tested in certified laboratories for temperature rating according to the European Norm EN 13537. Here’s an excerpt from an information sheet on the subject:

All Sea to Summit Unisex Sleeping Bags are listed using the LOWER limit, which is appropriate for male sleepers. Women end-users should use the COMFORT rating of a Unisex bag.

All Sea to Summit Women's Specific Sleeping Bags are listed using the COMFORT rating. 

Please note: Both ratings would require the sleeper to be dressed in Expedition Weight base layers and have adequate insulation underneath the sleeping bag in the form of a sleeping pad or sleeping mat. The EN test protocol uses a sleeping pad with an R-Value of at least 4.
