标准摘要
[中文适用范围]： IEC 60068 的这一部分提供了三种标准化和协调的测试方法，用于确定样本承受指定严重冲击的能力。它特别用于在评估产品安全性时证明可接受的稳健性水平，并且主要用于电气技术项目的测试。它包括对样本施加规定次数的冲击，该冲击次数由冲击能量定义并沿规定方向施加。 IEC 60068 的这一部分涵盖了从 0@14 J（焦耳）到 50 J（焦耳）的能量级别。三种类型的测试设备可用于执行这些测试。附件 C 提供了这方面的一些指导。 [外文原描述]： IEC 60068-2-75:2014 provides three standardized and coordinated test methods for determining the ability of a specimen to withstand specified severities of impact. It is used, in particular, to demonstrate an acceptable level of robustness when assessing the safety of a product and is primarily intended for the testing of electrotechnical items. It consists of the application to the specimen of a prescribed number of impacts defined by their impact energy and applied in the prescribed directions. This part of IEC 60068 covers energy levels ranging from 0,14 J (joules) to 50 J (joules). This second edition cancels and replaces the first edition, published in 1997, and constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: - reconsideration of some values in Tables 1 and 2. Although some values are no longer recommended, they have been retained as alternatives for historical consistency purposes.
