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:
: e; d( |$ {; C' |6 n1.check the related standards and find the related requirements for your products, such as follows:
( t3 k! G/ j/ {$ U, Uon the production line(routint test): 1.2k for 2 seconds, with the leakage current 3mA
. B$ Q6 \1 x5 d' K# E' [for type test:1kV for i minute, with the leakage current 3mA, }( ?, e; A$ L7 a1 k$ _
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.
. D9 |0 i$ m! r$ X& n& X- Z3. do the test, if breakdown, then reject, if not, accept..9 I; i2 Q8 _, ?4 @* a' h
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... |
