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:! l5 @* E" o2 ?* } W5 R; C6 W
1.check the related standards and find the related requirements for your products, such as follows:8 p, r, W- K9 ~' ]" c3 U/ o1 E8 u1 S
on the production line(routint test): 1.2k for 2 seconds, with the leakage current 3mA5 f) F( O) {6 ^: M4 D$ ^ R- g& }
for type test:1kV for i minute, with the leakage current 3mA: S7 G" n$ T2 t8 m- q
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.
" c. M9 c' H4 x/ u) h3. do the test, if breakdown, then reject, if not, accept..
- Q9 G4 F' u2 z% ?( c* m* snormally, 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... |
