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 [) [5 G( C' i6 D X8 u2 F
1.check the related standards and find the related requirements for your products, such as follows:1 x* v) x# K: j4 `+ x0 e
on the production line(routint test): 1.2k for 2 seconds, with the leakage current 3mA
g- d3 `/ ?: _, F8 Y C( [for type test:1kV for i minute, with the leakage current 3mA
% y8 j5 b) }! g0 E) G2. 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.
5 I# ], t) F/ w+ J% L) y9 U! I3. do the test, if breakdown, then reject, if not, accept..
+ K; j& ?$ t2 enormally, 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... |
