The entire 801 Series is obsolete and replaced by the EN61000-4-X series; 61000-4-2, 61000-4-3, 61000-4-4 and 61000-4-5. It sounds like the product standard you have is out of date and needs to be revised, if it hasn't been already, to call out the new standards. Today, virtually all product standards call for testing to 61000-4-2 (ESD), 61000-4-3 (RF Radiated), 61000-4-4 (EFT), 61000-4-5 (Surge), 61000-4-6 (RF Conducted) and 61000-4-11 (Dip and Interrupts). Additionally, virtually all product standards require emissions testing as well. It is possible a revision of EN50091-2:1995 would not call for surge testing, but more than likely, it will. I would think if surge immunity were to be required for any set of products, UPS's would be at the top of the list..... I'd recommend it whether you're required to do surge testing or not. (Be careful, I sell surge testers, so you better get other opinions!) Good Luck.

Hi all, I am reviewing EN50091-2:1995 to determine the immunity requirements for UPS systems. According to the harmonized list, this is the correct version of the standard under the EMCD. It calls for radiated emissions, IEC 801-2, -3 and -4. It then says 801-5 is under consideration. Our customer is requesting 801-5, but based on how I read the standard, it is not required at this time. Could that be true? Kind Regards, Sam Wismer Engineering Manager ACS, Inc.
