其他地方指的是标准的其他条款,例如附录U,测试时间很明显的说明可以减少到1s,试验电压值降低10% Where, elsewhere in this standard, ROUTINE TESTS are required to be conducted in accordance+ M0 n0 ~$ M( e4 B; I: K( Z1 G# S
with 5.2.2, it is permitted to reduce the duration of the electric strength test to 1 s and to* N5 D1 k$ K2 s ]* t
reduce the test voltage permitted in Table 5C, if used, by 10 %.
