1.1 本试验方法包括确定树木支架防坠落系统（FAS）和组件或子系统的负载能力。 1.2 本试验方法适用于狩猎环境中使用的设备，需要个人防护以防高空坠落，并适用于此类设备的制造商、分销商、购买者和用户。 1.3 以英寸-磅单位表示的值应视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准值。 1.4 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建立适当的安全、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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 本试验方法旨在测量树架FAS和组件或子系统的最大制动力和动态强度。本测试旨在用于项目质量保证和生产质量控制。它不是一个独立的材料或产品验收测试。

1.1 This test method covers the determination of the load capacities for treestand fall arrest systems (FAS) and components or subsystems. 1.2 This test method addresses equipment used in hunting situations requiring personal protection against falls from heights and applies to the manufacturers, distributors, purchasers, and users of such equipment. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 ====== 4.1 This test method is intended to measure the maximum arrest force and dynamic strength on treestand FAS and components or subsystems. This test is intended for program quality assurance and production quality control purposes. It is not intended to be an independent material or product acceptance test.
