Ryan,
Thanks but my bottom line question to the group is which committe decides how these tests are done. Again checking with an ohmeter for earthing test during the production-line test as written in these appendix pages (and I have access to tens of product categories) is not a good test. Do you agree that at least some current should be injected to the circuit to yield "acceptable" or "reject"? The question now is how many amperes for production-line tests.

You can't get from UL1950 to the production line tests. I know it's called out on the Factory Audit Manuals... but where does the requirement come from? What I got a hold of was a UL procedure for their Follow up Services personnel. But I hope you can use this document to further track down the source of the requirement. Try doing a search in Google for "File E211188 Vol. 1" This is where I saw it.

I don't believe any North American standard specifies production-line tests. For UL, production-line tests are specified in the front of each Volume of the UL Follow-Up Services (FUS) procedure. For CSA, I believe production-line tests are specified in the product report. Best regards, Rich This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
