1.1这些试验方法包括测定产品的冲击脆性。该脆弱性信息可用于设计运输产品的集装箱。它也可用于提高产品的耐用性。在这些试验方法中，在外部容器内运输的单位或消费品包装被视为产品。概述了两种试验方法，如下所示: 1.1.1首先使用试验方法A来确定产品的临界速度变化。 1.1.2其次使用试验方法B，以确定产品的临界加速度。 1.2以英寸-磅或国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.3本标准无意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。 有关具体的预防说明，请参阅第节。 ====意义和用途====== 这些测试方法旨在为用户提供有关产品冲击脆性的数据，这些数据可用于选择运输集装箱的最佳缓冲材料或产品设计修改。

1.1 These test methods cover determination of the shock fragility of products. This fragility information may be used in designing shipping containers for transporting the products. It may also be used to improve product ruggedness. Unit or consumer packages, which are transported within an outer container, are considered to be the product for the purposes of these test methods. Two test methods are outlined, as follows: 1.1.1 Test Method A is used first, to determine the product's critical velocity change. 1.1.2 Test Method B is used second, to determine the product's critical acceleration. 1.2 The values stated in either inch-pound or SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section. ====== Significance And Use ====== These test methods are intended to provide the user with data on product shock fragility that can be used in choosing optimum-cushioning materials for shipping containers or for product design modification.
