1.1 本试验方法包括在标准负载下测定睡袋的高度。 1.2 该测试方法使用适用于实验室的物理高度测量。 1.3 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。在文本中，英寸-磅单位显示在括号中。每个系统中规定的值不是精确的等价物；因此，每个系统应相互独立使用。组合两个系统的值可能会导致与试验方法不一致。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 在这种情况下，该测试方法可用于规范、设计和质量控制。Loft本身并不是用来预测睡袋的热性能。

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 establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== 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.
