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:% W; r3 W' `( k* u# B5 J7 `2 d
1.check the related standards and find the related requirements for your products, such as follows:
' H8 D( Z$ l2 m: i& ion the production line(routint test): 1.2k for 2 seconds, with the leakage current 3mA
) E8 X0 n' F4 i# C/ w" dfor type test:1kV for i minute, with the leakage current 3mA5 i& a/ V( J4 W' z0 m, N
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.! }# h' X, z) u0 } b
3. do the test, if breakdown, then reject, if not, accept..0 l# k) A; D0 i- T- S9 Y
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... |
