This test method covers a means to measure the end use flammability, for example, burn rate of sleeping bags which use various materials and constructions in their manufacture, and provides labeling requirements to facilitate the identification of products conforming to this test method. This test method defines the procedures described in the flammability standard CPAI-75 which has been the accepted standard in the sleeping bag industry in the U.S. for over 30 years. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire-risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. 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.
