1.1 本试验方法涵盖了确定攀爬和梯架、攀爬杆（分段和连续）和三脚架/塔相对于制造商额定能力承受重复荷载的能力的程序。有关每个主体单元的实际规范要求，请参阅规范 第3249页 . 1.2 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。 1.3 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。 1.4 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====== 5.1 本测试方法旨在质量保证和生产控制，并认识到个人使用情况会有很大差异。本试验方法并非独立的材料或产品验收试验。

1.1 This test method covers the procedures for determining the capability of climbing and ladder treestands, climbing sticks (Sectional and Continuous), and tripods/towers to withstand repeated loading relative to the manufacturer's rated capacity. For actual specification requirements for each subject unit refer to Specification F3249 . 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 test method is intended for quality assurance and production control purposes with recognition that individual usage will vary considerably. This test method is not intended to be an independent material or product-acceptance test.
