1.1 This test method covers determination of the insulation value of a sleeping bag. It measures the resistance to dry heat transfer from a constant skin temperature manikin to a relatively cold environment. This is a static test that generates reproducible results, but the manikin cannot simulate real life sleeping conditions relating to some human and environmental factors, examples of which are listed in the introduction.
1.2 The insulation values obtained apply only to the sleeping bag, as tested, and for the specified thermal and environmental conditions of each test, particularly with respect to air movement past the manikin.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
