That is the correct version of the standard as far as I know, and I agree it does not require application of the 801-5 surge immunity requirements. I too find that surprising, since surge is one of the most basic and longest-standing immunity considerations, and real life problems occur if it's ignored. Regardless of the standard's content, however, the customer can of course demand whatever they want, and you can voluntarily do surge testing too. It may cover you if and when EN50091-2 is reissued, at which time it will likely add the surge requirement, along with 316 other immunity tests you and I have never even heard of.

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.
