1.1 这些试验方法确定了泡沫就地包装材料的减震特性。 1.2 试验方法A 使用自由落体包装跌落试验装置。 1.3 试验方法B 使用冲击试验装置。 1.4 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。 1.5 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、健康和环境实践，并确定监管限制的适用性。 1.6 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 通过这些方法获得的数据可用于确定泡沫就地包装材料的传递冲击缓冲特性。这些数据允许设计缓冲系统，在分销生命周期内充分有效地使用泡沫保护货物。 5.2 与通常仅测试缓冲泡沫的其他方法不同，这些方法旨在评估泡沫- 采用泡沫就地包装材料的就地缓冲材料。具体而言，该方法包括同时使用塑料膜、泡沫和该包装方法中通常使用的盒子。看见 图1 . 图1 准备好进行测试的样本

1.1 These test methods determine the shock-absorbing characteristics of foam-in-place packaging materials. 1.2 Test Method A uses a free-fall package drop test apparatus. 1.3 Test Method B uses a shock-test apparatus. 1.4 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. 1.5 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. 1.6 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 Data obtained by these methods may be used to determine the transmitted shock cushioning characteristics of foam-in-place packaging materials. These data allow design of cushioning systems that can provide adequate and efficient use of foam for protection of goods during a distribution life-cycle. 5.2 These methods, in contrast to other methods that usually test only the cushioning foam, are designed to evaluate foam-in-place cushioning materials in a manner in which the foam-in-place packaging material is used. In particular, the method includes simultaneous use of a plastic film, the foam, and the box usually used in this method of packaging. See Fig. 1 . FIG. 1 Specimen Ready For Test
