1.1 该测试方法涵盖了通过将下落的导向台板组件掉落到静止样品上获得的加速度时间数据来获得包装材料动态冲击缓冲特性的程序。本试验方法不涉及外包装组件的任何影响或贡献。 1.2 所获取的数据可以用于单个点，或者用于开发被测特定材料的动态缓冲曲线。这些数据可用于在特定输入条件下对不同材料进行比较，或根据性能规范对材料进行鉴定。当试图比较不同方法的数据或使用这些数据预测包内性能时，应注意。根据所关注的特定材料，这些数据（来自不同程序或用于预测包装内性能）的相关性可能高度可变。 注1: 可供考虑的替代和相关方法是试验方法 D4168 。 1.3 以英寸-磅为单位的数值应视为标准。括号中给出的国际单位制仅供参考。 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。 1.5 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 通过该测试方法获得的动态缓冲测试数据适用于缓冲材料，而不一定与包装中获得的数据相同。除了包装的影响外，数据还可能受到试样面积、厚度、加载速率和其他因素的影响。

1.1 This test method covers a procedure for obtaining dynamic shock cushioning characteristics of packaging materials through acceleration-time data achieved from dropping a falling guided platen assembly onto a motionless sample. This test method does not address any effects or contributions of exterior packaging assemblies. 1.2 The data acquired may be used for a single point or for use in developing a dynamic cushion curve for the specific material being tested. Such data may be used for comparison among different materials at specific input conditions, or qualifying materials against performance specifications. Caution should be used when attempting to compare data from different methods or when using such data for predicting in-package performance. Depending upon the particular materials of concern, correlation of such data (from among differing procedures or for predicting in–package performance) may be highly variable. Note 1: Alternative and related method for possible consideration is Test Method D4168 . 1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only. 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 ====== 5.1 Dynamic cushioning test data obtained by this test method are applicable to the cushioning material and not necessarily the same as obtained in a package. In addition to the influence of the package, the data can also be affected by the specimen area, thickness, loading rate, and other factors.
