1.1 本规范定义了测试救援系统和部件时使用的质量。 1.2 群众代表可能连接到救援系统或部件的人员和设备。然而，质量并不代表任何特定类型或种类的救援人员或设备。 1.2.1 所选择的质量在过去或目前已用于救援系统和部件的测试。将测试限制在本规范中列出的质量范围内，可以对过去、当前和未来的测试结果进行有意义的比较。 1.3 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.4 本规范的用户应确定哪个质量代表被测系统或部件上的人员和设备。 1.5 就本规范而言，当代表质量的物体在地球上任何地方的空气中称重时，质量和重量是同义的。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者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。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification defines the masses to be used when testing rescue systems and components. 1.2 The masses represent personnel and equipment that may be attached to a rescue system or components. However, the masses do not represent any particular type or kind of rescuer or equipment. 1.2.1 The masses chosen have been used in the past or are in current use in testing of rescue systems and components. Limiting testing to the masses listed in this specification allows meaningful comparisons between past, current, and future test results. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 The user of this specification shall determine which mass(es) represent(s) the personnel and equipment attached to the system or component under test. 1.5 For the purposes of this specification, mass and weight are synonymous when the object(s) representing the mass(es) are weighed in air anywhere on Earth. 1.6 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. 1.7 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.
