如题所示,关于IEC60950-1:2005中Routine Test 耐压测试时间与电压设定,我本人从标准中一直没看到有比较明确的说法。) A$ L- W* i* U6 O# g
根据5.2.2章节有如下内容:
5 \' K' `1 k7 A0 ]) }) lWhere, elsewhere in this standard, ROUTINE TESTS are required to be conducted in accordance

Where, elsewhere 这两个单词,不好理解到底是哪里。是否也包括LN对地?我们产线上打的地方就是LN对地。, M) d1 G/ a! c+ ?5 U( i: [

希望各位可以引出标准进行讨论。 |
