An additional method to obtain safety approval in Australia (if it is still allowed) and other countries that we did when I worked for Zenith Data Systems was to obtain a CB Test Report and Certificate based on the appropriate IEC version of the standard (for IT equipment it is IEC950). We obtained this from NEMKO, but now I understand you can get CB R&C in North America from UL, ETL, CSA, etc.
The purpose of the CB scheme is so testing can be done at one lab and the test results would have to be excepted by other labs, though a review of the product may be requested. For Australia, we would send our CB R&C to a company representative in Australia. He would take it with any additional information to the proper authorities. At this point I understand it is a paperwork thing and only takes a few weeks to obtain an approval. I believe this method is still used. Maybe others could comment on their experience with using the CB scheme. Brian Kunde LECO Corp.
