Peter, The note you are referring to is in the OJEC. If you wanted to paraphrase it, one option would be "We (the Commission) have the responsibility for directives and not you (CENELEC). Therefore, we'll set the Date of Cessation to be equal to the Date of Withdrawal providing that we can be convinced that the date is correct." I seem to recall that Dates of Cessation have been changed from one version of the OJEC and the next (following discussions in the CENELEC BT) as regards safety standards. Life has been even more 'interesting' as regards EMC standards.

I suppose this is how/why CENELEC put dates in their versions of EN60950 (and possibly others) in the first place, or perhaps Note 1 was included to accommodate CENELEC's habits. It may be that Note 1 will disappear as the EC has their way and older editions of standards scroll off the list. I am still dicing the finer points of language. I will report back whatever I might find and hope that anyone with official and unambiguous information related to this query will step forward. Regards, Peter L.

I have not tried to find the exact text but I can imagine that those who wish to look for it would need access to documents from the CENELEC Technical Board (CENELEC BT). - Although I do not have all the list of standards published in the OJEC in relation to the LVD, I do recall that it was not always the case that the list had the column entitled "Date of cessation of presumption of conformity of the superseded standard Note 1". The first version of the revised list I have stored on my PC is dated 1999 (but this may not be the first such list). Nevertheless, you can see that there would be confusion if a standard were to give one date and the OJEC were to give another date. Eliminating the 'certification clause' leaves the OJEC as the only date for the expiree of a standard, with the Commission being in overall control of when that date is (although in practice this would normally be agreed with the CENELEC BT).
