1.1本试验方法涵盖了一个程序，该程序通过加速度时间数据获得包装材料的动态冲击缓冲特性，该加速度时间数据是从将下落的导向压板组件跌落到静止样品上获得的。本试验方法不涉及外部包装组件的任何影响或贡献。 1.2获取的数据可用于单点或用于为被测试的特定材料绘制动态缓冲曲线。这些数据可用于在特定输入条件下比较不同材料，或根据性能规范鉴定材料。当试图比较不同方法的数据或使用此类数据预测包内性能时，应小心。根据关注的特定材料，这些数据的相关性（来自不同程序或用于预测 – 包装性能）可能变化很大。 笔记 1-可能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值。括号中给出的国际单位仅供参考。 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。 ====意义和用途====== 通过本试验方法获得的动态缓冲试验数据适用于缓冲材料，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 problems, 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. ====== Significance And Use ====== 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.
