This test may also be used for similar devices when
18、specified in a detail specification. The object of this test is to detail a standard test method to assess the ability of a component to carry its specified current, at room temperature, without exceeding a specified temperature rise. 1.2 Normative references The following normative documents contai

For dated references, subsequent amend- ments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IEC 60512 are encouraged to investigate
20、 the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
