1 Scope
This part gives a method of test which provides a standard procedure to determine the ability of components, equipment and other articles (hereinafter referred to as specimens), to withstand specified severities of sinusoidal vibration.
The purpose of this test is to determine any mechanical weakness and/or degradation in the specified performance of specimens and to use this information, in conjunction with the relevant specification, to decide the acceptability of the specimens. In some cases, the test method may also be used to demonstrate the mechanical robustness of specimens and/or to study their dynamic behaviour. Categorization of components can also be made on the basis of a selection from within the severities quoted in the test.
