BS EN 13538 is a series of European standards that discusses the determination of dimensional characteristics of sleeping bags with a focus on volume under load and easiness of packing. BS EN 13538-3 is the third part of the multi-series on the determination of dimensional characteristics of sleeping bags that specifies a method of measurement of the volume under a load of sleeping bags and a method of calculation of easiness of packing of sleeping bags filled with feather and/or down.
BS EN 13538-3 on dimensional characteristics of sleeping bags is useful for:
The sleeping bag is stuffed unfolded inside the cylinder. Then the cylindrical load is lowered onto the sleeping bag inside the cylinder.
BS EN 13538-3 discusses volume under load, easiness of packing, measuring device, conditioning of test specimen, procedure, test results, the volume of the sleeping bag under load, calculation of the easiness of packing, and test report.
