As noted by the Other Brian, some things to pay attention to are if the end product is subjected to an overvoltage category or pollution degree beyond what is found in the standard office environment and potential exposure to liquids.
Some (hopefully) helpful information below found with "the Emperor's search engine". ;) http://www.tuv.com/media/usa/nabrochures/Test_and_Measurement.pdf http://www.nemko.co.uk/node/64 https://www.mail-archive.com/[email protected]/msg66382.html https://www.mail-archive.com/[email protected]/msg28698.html https://www.linkedin.com/groups/Dielectric-strength-testing-in-IEC-1899348.S.5842697233245425668 I don't think I found the papers that Mr. Oconnell (the original Brian?) was referring to, but I'd be interested to see them if someone else has better luck.
