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.
