20、s within the scope of IEC technical committee 48. This test may also be used for similar devices when specified in a detail specification. The object of this test is to define a standard test method to assess the ability of components to withstand specified severities of shock. 1.2 Normative referen

21、ces The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 60512. For dated references, subsequent amend- ments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this par

22、t of IEC 60512 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
