How EN Bag Testing Is Done
For EN 13537 temperature tests, a full-size mannequin with heaters and temperature sensors is dressed in 1 layer of long underwear and a hat. It is placed inside the sleeping bag being tested. The bag is laid atop an insulating sleeping pad inside a climate-controlled chamber. The mannequin is heated to simulate body warmth and measurements are taken of the air in the climate chamber and the "skin" surface of the mannequin. From these measurements, the insulation value of the sleeping bag is calculated. These calculations provide the 3 EN ratings described above.
