Yes, normally you must find out the corresponding test standards about your products, but from your description about the dielectric test, I guess this test should be initiated on the production line.so follow the steps as follows:
- ]4 i* I9 ~0 m- W8 j+ t' ]1.check the related standards and find the related requirements for your products, such as follows:. x6 u0 C' ?: R: ^* U& o
on the production line(routint test): 1.2k for 2 seconds, with the leakage current 3mA) w# s- T8 ?, k4 O# I% m
for type test:1kV for i minute, with the leakage current 3mA- w4 @8 Q5 ^! T
2. set your own test instructions, and specify the test procedure, maybe, your test requirements are more severe than the standards' requirements, that's also ok for robustness.2 N& C3 `0 @) I& C# y2 d
3. do the test, if breakdown, then reject, if not, accept..3 r+ X4 i& b, i4 S
normally, for UL, there is no requirement for the leakage current, and as per the experience, 10mA, but for other parties, 3.5~10mA is recommended... |
