Significance and Use
3.1 In this context, this test method can be used for specifications, design, and quality control. Loft, in and of itself, is not to be used to predict the thermal properties of a sleeping bag.
1.1 This test method covers the determination of the loft of a sleeping bag under a standardized load.
1.2 The test method uses a physical height measurement applicable in the laboratory.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the test method.
1.4 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
