Everyone This issue has been discussed in the CENELEC EMC committee, TC210, leading to guidance that I expect will be published in an updated CENELEC Guide 25. The relevant text reads as follows.
"In some cases, a harmonised standard will make reference by dated reference to another harmonised standard, each standard being listed in the OJEU for the EMC Directive. In such cases, the specific edition of the referenced EN is to be applied irrespective of whether that edition is currently listed in the OJEU. This follows the principle that the primary standard provides the requirements for the apparatus, and hence presumption of conformity in respect of the EMC Directive as described in Annex ZZ of that standard (see Annex 5 of this guide). See also 2(e) below for the specific example where the standards are based on international versions. .... 2(e) In some cases, a harmonised standard (described as the "primary" standard below) may give a dated reference to another harmonised standard (for example EN 61000-6-3:2007 makes reference to EN 55022:2006 for test methods). It will be appreciated that the referenced standard is listed in the OJEU in its own right, and the question arises as to whether the dated reference, or the date of cessation of presumption of conformity given in the OJEU list, should prevail. The principle to be followed is that the dates given in Annex ZA of the primary product/product family/generic standard prevail. The committee responsible for the primary harmonised standard sets the total requirements, and this includes the specific editions of referenced standards to be used. The principle of the application of dated references is the same whether the referenced standard is a basic standard or a product family standard." It is expected that this text will be approved at the next Technical Board meeting in November, and published shortly thereafter. Current versions of this Guide (and Guide 24) may be downloaded free of charge at http://www.cenelec.eu/Cenelec/CENELEC+in+action/Horizontal+areas/EMC/default .htm The CENELEC website will show when the new editions of Guides 24 and 25 are available.

The Official Journal lists EN61000-3-2:2006. "IF" there was a dramatic change between the two, for a proper DoC would both versions need to be applied?

That's what IEC is working on. There is a proposal that committee secretaries review all normative references (particularly in standards used in a regulatory context) annually to se if they need updating. I am not describing the whole procedure because it's still under discussion, but steps will be taken in any system that is introduced to make the process as easy and swift as possible. -- OOO - Own Opinions Only.
