26、cedure The Test 11g method and duration shall be specified in the detail specification. The test severity is defined by the test method, chosen from Table 1, this table is in accordance with Test Ke of IEC 60068-2-60; the test duration, preferred values are 4, 7, 10, 14 and 21 days. Guides for the s
27、election of test methods and test duration, and descriptions of test apparatus are given in IEC 60068-2-60. During the test, specimens are not electrically loaded.
