Recently I have seen some questions in this group regarding hi-pot testing and IEC1010 and prEN50116.
I am not familiar with prEN50116 (perhaps someone can enlighten me about that), but I am familiar with IEC1010 and hi-pot testing. In amendment 2 to IEC1010 Annex K changes from Informative to Normative (becomes required). This Annex describes the routine manufacturing line testing for products which includes hi-pot testing. I am sure that this will be added to the harmonized equivalents as well, ANSI/ISA S82.01, CSA 1010.1, EN61010-1, and UL3111-1. Also, I believe that hi-pot testing is required by UL as well as CSA in the majority of their electronic product categories. It may be in the Section General or in an Appendix rather than in the Section which describes the product, but I feel sure that UL believes that it is required. It would also surprise me if organizations like VDE and TUV don't also feel that hi-pot testing is a requirement. I believe that we would be doing hi-pot testing at this company whether it was required by the standard or not, because we feel it is a good thing to do. If my understandings here are not accurate, I am confident that someone will now let me know. Richard Payne Tektronix, Inc. richard.pa...@tek.com
