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$ j9 ~/ M& ] }1 N% y根据5.2.2章节有如下内容:# z2 e1 ?) i' ?7 l' W

' R0 Z+ w* Z% d5 L% G) C这个内容说时间可以减少到1秒,电压可以根据表C来进行,但是说得很模糊,尤其是
3 [: q4 {: @. @' BWhere, 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。

但是我一直觉得Annex U 只适用于Insulated winding wires for use without interleaved insulation,而不是用于我们产线上的位置(我们产线一般就打LN对地)。' s1 w: \- @, l. ^
