Re: EMC standards for UPS supplies
Try 50091-2. That's the Euro one and it includes EMI immunity and covers the different operating modes. For domestic products (assuming you're in the US, that is) the normal FCC rules apply - just be sure to test all the operating modes (to cover all the bases, 0%, 50%, and 100% load in both AC and battery operation should be a good place to start - and will probably suffice for the report). A hint from experience - any narrowband emissions will probably stay the same between modes - it is the broadband switching noise (for radiated, probably 30-250 MHz or so) that will vary between modes. This should help during the 100% load battery scans that need to be completed in a matter of minutes - just be sure to test to make sure that this is indeed the case. One other comment - in the case of 3 phase systems, you may want to check to see if the manufacturer has 50091-2 approvals for the EU version. 3 phase systems vary here and in the EU and I know of at least one manufacturer who specialized the compliance tests to reflect the countries in which the product could be installed. In other words, their US version of the product was only labeled for the FCC, while their EU version was tested to 50091-2 (and maybe FCC as well??). A domestic sample would most likely have been the FCC only type, but an EU version may well be already approved.

Re: EN61326 and deviations
I read in !emc-pstc that charles.mar...@ps.ge.com wrote (in 6BBE5C5603D 0d611a06f0002a5d6556401497...@nyschx22psge.sch.ge.com) about 'EN61326 and deviations' on Mon, 7 Apr 2003: Does this mean I can Pass, for example, a product that meets criteria B for 4-3, Rad Im. at let's say 5.5 V/m just in a few frequencies only. **CriteriON**. Yes, provided the immunity lapses are not too broad in frequency. How broad is 'too broad' depends on what services use the band(s) where the lapses occur. How much highlighting would I have to do in the Test Report and for the product spec, what level of details? Maybe a graph. Would this include the DoC? Not in the DoC. Could I say we meet Criteria A, but in a few frequencies we meet criteria B, call for more details. I don't think that's enough; you should provide the details up-front. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

FDA requirements for beauty treatment device
I've been asked to take a look at the requirements for a beauty treatment product which the client wants to push for the US market. It works by passing a small current through the skin. The client is adamant that this is not a medical device in the sense of the EU Medical Devices requirements since they make no therapeutic claims. We have not been responsible for CE marking it so I'm reserving my own judgement on this point, but I'm certainly not going to assume that the semantic same work around will provide a release from the applicable legislative requirements in the US. I've spent sometime looking at the FDA site this morning, but I'm having trouble find stuff which might be useful in among the vast amount of information on true medical devices and on cosmetics. This unit might best be described as a 'cosmetic device' If there's someone out there who can point me to a quick primer which gives details of what the FDA consider to be within the scope of their remit, and what the requirements are for equipment which is within their remit, this would help immensely in getting to grips with the project. Thanks Nick. P.S. As to whether it actually works or not, well, I haven't seen any changes yet, but maybe I'm just too beautiful already!
