RE: North American Production-Line Tests; ANSI or Other
I'm sorry but I seem to have missed the purpose of this question. Is it to find the source document for the simple and purist reason of Knowledge? I most sincerely hope that you are forced into justify these essential tests. Gregg Having lost sight of our objectives we redoubled our efforts.

RE: North American Production-Line Tests; ANSI or Other
Going back a ways, UL 1459, ed. 3 Sections 72 and 73 along with Appendix C provide quite a lot of details regarding production line tests for telecom equipment. I have not been able to find a reference within UL 1459 which might indicate a deeper source of the requirements as reflected in 1459. My opinion and not that of my employer.

RE: North American Production-Line Tests; ANSI or Other
Sir For some time, both UL and TUV have required my employer to test with a 25A to 40A current, depending on the branch circuit rating that the device can be connected to (as specified in the Conditions of Acceptability). Also, CSA has (at least for as long as I have been employed here) always required Ground Continuity tests (both Production and Type tests) to be performed at at least 30A for 950, 1010, and 601 devices.

Re: North American Production-Line Tests; ANSI or Other
Hi Peter: I am trying to find the rationale why production-line ratyhing tests in North America are usually done with a simple ohmmeter and without passing a current of say 25 A through the circuit. There must be some rationale of doing it this way somewhere. I can't answer that question. But, I can provide you with data that says that the production-line 25-amp test is no better than a simple continuity test. See: http://www.ewh.ieee.org/soc/emcs/pstc/psn/ Then, view the following files: 97V10n1.pdf 97v10n2.pdf In each document, turn to Technically Speaking.

RE: North American Production-Line Tests; ANSI or Other
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.
