Hi Rich,
I did not see it in UL60950 2nd or 3rd edition either. If I remember correctly it was in UL478 and still is required in many other Standards. Any thoughts on why it was not carried into the new Standards and/or why ground continuity wouldn't be required as a routine test?? I would love to see 108-570, thank you!

In fact, see 1.4.2: Type tests Except where otherwise stated, the tests specified in this standard are type tests. In IEC product safety standards, tests can only be "type" tests. But, this principle is not universally followed. (UL 60950-1 was based on IEC 60950-1, but not identical.) Not only that, TC108 is publishing a routine test standard, IEC 62911 (aka 108-570). It is likely that UL will pick up on this and publish a "routine" test standard that can apply to a number of their standards. Best regards, Rich (I can send you a copy of 108-570 if you would like.)

Forgot about, but found "routine tests". What's odd to me is it doesn't seem ground continuity is required as a routine test.
