有要做的，第19章里面有说到的作者: kk20082008 时间: 2010-6-3 19:46
当然是要做，类似EMC的部分。作者: kamleung 时间: 2010-6-4 17:08
If your product is AC operated, then Surge test is necessary in both the EMC standard (EN55014-2) and Safey (EN60335-1). Please note that the test levels and the PASS requriements are not the same in the EMC and Safety standards.6 ~$ l/ @& G2 y+ V

IEC 60335-1 clause 19.11.4, 对带有待机状态开关 或通过电子断开获得断开位置的开关的器具需要进行19.11.4.1-19.11.4.7的试验，其中19.11.4.4需要对器具电源接线端子进行电压浪涌测试！9 b0 D) A: C- S2 l O1 Y* V

Test level 3 is applicable for the line-to-line coupling mode, a generator having a source impedance of 2 Ω being used. Test level 4 is applicable for the line-to-earth coupling mode, a generator having a source impedance of 12 Ω being used.

you must know, there are to surge tests for the products: 6 I+ C, L+ `* K2 `1. One is for safety requirements, to verify the insulation characteristics of the products, and sometimes it also can be called impulse tests; : Z4 l' h, r/ Q, e4 N2. The other is for EMC requirements, to monitor the impact of the lightning to the products. ) ^8 p( X9 [+ e* y * |" K0 \3 e& @# W& v; j' J6 u9 iBut the basic waveform of the above two tests are similar.....作者: cylam128 时间: 2010-6-16 09:03
