There are not that much standards applicable to each and every product, unless you never read the list. If you do not know which standard is applicable, one also can opt for the generic standards set.
The phenomena based approach is imho the way if you cannot afford the use of a consultant. So in order of best results: 1. Ask a consultant 2. search for an applicable standard for harmonics and flicker (4 exist <16 and >16 amp) 3. search the scope of harmonized standards for the best fit for emissions 4. search the scope of harmonized standards for best fit for immunity 5. Be aware that sometime 3&4 are 2 different standards, and sometimes 3&4 are in one standard 6. Verify you actually selected the applicable version (LOOK at the DATE in the list , newest is not always best). 7. Verify you found and read all valid amendments ad corrigenda 8. Search Google for a DoC for a similar product and copy; you will probably end up with an obsolete list 9. Now you are really confused: go back to 1. Yours truly.... Regards, Ing.

Each can be slightly different or vastly different from each other. 2) Even sight differences in application and use could force you to look at other standards. 3) Even if the EU produced legally enforced guidelines for all the combinations above, finding the guideline in the first place would still be a huge job. And what do you do if nothing fits 2) Also using harmonised standards is just one route Regards Ian White Compliance and Reliability -----Original Message----- From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of david.cole...@selexelsag.com Sent: 21 December 2011 11:58 To: Charlie Blackham Cc: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] harmonics & flicker Charlie, Yours and John Woodgate's responses tell me what I already know - but don't answer the fundamental question, of why there is not a legally enforceable document (and the EMC Directive Guide is not), that tells the uninitiated what standards their equipment needs to comply with, if they are using the harmonised stds route? Can they reasonably be expected to read the scope of every harmonised std? Why did the writers of 61326 feel it necessary to include reference to 610003-3-2 & 3-3, but the writers of 55022 did not? Best Regards, Dave Coleman From: Charlie Blackham <char...@sulisconsultants.com> To: EMC-PSTC@LISTSERV.IEEE.ORG Date: 21/12/2011 11:42 Subject: Re: [PSES] harmonics & flicker Dave You are not required to be compliant with standards – you are required to be compliant with the protection requirements of the EMC Directive. Ways of demonstrating compliance are discussed in “The Guide for the EMC Directive 2004/108/EC (8th February 2010)”, available from http://ec.europa.eu/enterprise/sectors/electrical/documents/emc/guidance/index_en.htm Section 3.2 covers the use of Harmonised Standards to obtain a presumption of conformity, including: Generally the three main aspects to be covered are: – high frequency emission (related to radio protection); – low frequency emission on the mains supply (harmonics, voltage fluctuations); – Immunity to permanent and transient EMC phenomena. In reality most companies choose to test products to Harmonised Standards, using test equipment made by companies who sit on standards committees alongside test labs who perform the testing – but it’s not compulsory J Regards Charlie -----Original Message----- From: Dave Coleman [mailto:david.cole...@selexelsag.com] Sent: 21 December 2011 10:50 To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] harmonics & flicker That's my point - I'm aware of the requirement to be compliant with these standards, but I'm giving direction to others less knowledgeable and I need to refer to them to the text that states the requirement unambiguously. If these words are not in the product standards or in the directive, where are they?

The 'product family' is 'anything connected to the public low-voltage electricity supply'. The EMC Directive does not call up any standards. Complying with standards is one way of complying with the Directive. -- OOO - Own Opinions Only.
