1.1 本规程为提供树架的用户说明提供了指导。 1.2 以英寸-磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.3 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。 1.4 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。 ===意义和用途====== 5.1 本规程旨在发展和保持树架、登山杖（连续式和分段式）、三脚架和塔架说明书的统一性，特别是在质量保证和安全方面。 5.2 需要强调的是，使用这些做法不会改变通过与其他标准相关的特定测试确定的数据的有效性。

1.1 This practice provides guidance for providing user instructions for treestands. 1.2 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. 1.3 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. 1.4 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 ====== 5.1 This practice is provided to develop and maintain uniformity in practices for instructions for treestands, climbing sticks (continuous and sectional), tripods, and towers, particularly with regard to quality assurance and safety. 5.2 It is emphasized that the use of these practices will not alter the validity of data determined with specific tests related to other standards.
