IEC 60068-2-27 Shock Testing

IEC 60068-2-27 Shock Testing

The IEC 60068-2-27 shock test covers components, equipment and other electrotechnical products, which, during transportation, storage, and handling, or in use, may be subjected either to conditions involving relatively infrequent nonrepetitive or repetitive shocks.

The purpose of this test is to reveal mechanical weakness and/or degradation in specified performances, or accumulated damage or degradation caused by shocks. The shock test specified in IEC-60068-2-27 may also be used as a means of establishing the satisfactory design of a unit in so far as its structural integrity is concerned and as a means of quality control.

The IEC 60068-2-27 test is primarily intended for unpackaged specimens and for items in their transport case when the latter may be considered to be part of the specimen. If an item is to be tested unpackaged, it is referred to as a test specimen. However, if the item is packaged, then the item itself is referred to as a product and the item and its packaging together are referred to as a test specimen. When used in conjunction with IEC 60068-2-47, this standard may be used for testing packaged products.

Wherever possible, the test severity and the shape of the shock pulse applied to the specimen should be such as to reproduce the effects of the actual transport or operational environment to which the specimen will be subjected, or to satisfy the design requirements if the object of the test is to assess structural integrity. IEC 60068-2-27 requires the specimen to always be mounted to the fixture or the table of the shock testing machine during testing. The testing consists of subjecting a unit either to non-repetitive or repetitive shocks of standard pulse shapes with specified peak acceleration and duration.
