1.1 本规程为在实验室评估重量不超过150 lb（68 kg）的装运装置的能力提供了统一的基础，目的是使单包裹交付系统能够承受与配送环境相关的危险。这是通过将其置于一个测试计划中来实现的，该测试计划由分布周期中遇到的一系列预期危险元素组成。本规程无意取代材料规范或现有装运前测试程序。 1.2 尚未确定本规程是否适用于危险材料。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 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和健康实践，并确定监管限制的适用性。 具体预防说明见 1.1 . ====意义和用途====== 4.1 本规程提供了根据统一系统评估装运单元的指南，使用代表实际配送中发生的水平的既定测试方法。建议的测试水平基于有关运输和装卸环境的可用信息，以及当前行业/政府实践和经验。测试应按给定顺序在相同容器上顺序进行。为了用作性能测试，本规程要求被测试的装运装置保持未打开状态，直到测试序列完成。如果用于其他目的，如包装开发，在整个序列中的不同时间打开和检查装运装置可能会很有用。 然而，这可能会妨碍评估容器闭合对容器性能的影响。

1.1 This practice provides a uniform basis of evaluating, in a laboratory, the ability of shipping units, weighing up to but not exceeding 150 lb (68 kg), intended for the single parcel delivery system to withstand the hazards associated with the distribution environment. This is accomplished by subjecting them to a test plan consisting of a sequence of anticipated hazard elements encountered in the distribution cycles. This practice is not intended to supplant material specifications or existing pre-shipment test procedures. 1.2 The suitability of this practice for use with hazardous materials has not been determined. 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 1.1 . ====== Significance And Use ====== 4.1 This practice provides a guide for the evaluation of shipping units in accordance with a uniform system, using established test methods at levels representative of those occurring in actual distribution. The recommended test levels are based on available information on the shipping and handling environment, and current industry/government practice and experience. The tests should be performed sequentially on the same containers in the order given. For use as a performance test, this practice requires that the shipping unit tested remain unopened until the sequence of tests are completed. If used for other purposes, such as package development, it may be useful to open and inspect shipping units at various times throughout the sequence. This may, however, prohibit evaluating the influence of the container closure on container performance.
