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。- e; |0 E$ J$ V
根据5.2.2章节有如下内容:, q# O( F" ?8 G4 {, q/ ^' |5 {! M; A
Where, elsewhere in this standard, ROUTINE TESTS are required to be conducted in accordance' _) {0 y1 w5 T- ~4 ]. Y
with 5.2.2, it is permitted to reduce the duration of the electric strength test to 1 s and to3 L- r+ {9 l+ M; L- u6 f" m6 _
reduce the test voltage permitted in Table 5C, if used, by 10 %.& N8 L I& C- ]8 \* H; ^

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
9 w# v9 l1 m& ?, @6 Z GWhere, 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。9 `" u0 {, Y' @
. k* c* E" c T" Q! t还有在Annex U 中有如下内容:
