Re: EN 61000-3-2 Mandatory Implementation Dates?
I recently presented a paper on this subject, the commission has still not listed anything in the OJ about the implementation dates. You can find the paper on line off the following page ! http://www.emisoft.co.uk/special/hotemc.htm I do intend to keep this presentation up to date when/if the commission do publish something ? At 13:49 8/4/98 -0500, you wrote: In the March/April issue of Compliance Engineering in an article about harmonics measurements, there is mention of formal acceptance of a dow for 61000-3-2 of January 1, 2001. This means that equipment which fell under the scope of EN 60555-2, may continue to be tested to that (less restrictive) standard until January 1, 2001. However, unless I am missing something it also means that products that did not fall under 60555-2, but fall under the scope of 61000-3-2 (for example ITE) must immediately go from no harmonic emissions requirement to having to comply with the most restrictive 61000-3-2 requirements. Or... is it an option to test these products to 60555-2 until Jan. 1, 2001? Does the original June 1, 1998 dow have any meaning in this latest twist on the powerline emissions saga? If you have definitive information on this issue, please keep the EMC-PSTC group informed. Thanks!

Re: EN 55022 ITE Class A vs. Class B?
EN55022 is currently the relevant product family specification, hence the generic specification have no relevnace. EN55022 clearly states that class B is for equipment intended primarily for the residential/domestic environment and class A is for all other locations. Hence the Germany government [or any other] can not impose class B when EN55022 states class A ! Yes there is the problem of home office type situation but the specification does state primarily intended for home use ! What a manufacturer must be aware of is what are the demands of his customers. If EN55022 changes or a different relevant specification is issued then this situation may obviously change !

It so happens that I am dead serious about the fact that a large portion of the so-called approval problems stem from the abuse of language committed by well-willing engineers in standards and regulations, by and large written by industry. They believe that those who insist the accurate use of language, don't understand the issues, or are trying to avoid the issues. No doubt that may be true in some cases, but my general experience is that this is not pedantery and that they understand the issues a bit too well. However, as many now know quite well, I do not take myself too serious and recommend that nobody in this racket become too self rightuous.

RE: EN50082-1:1997
EN50082-1:1997 [BSEN50082-1:1998] includes the following dates:- dop - 1998-3-1 dow - 2001-7-1 the forward make NO reference to products which have previously satisfied 1992 requirements. Hence ALL products sold after this date [which need to use the generics] must meet this requirement on 2001-7-1 [year-month-day]. I will check back through my records but I do not remember any such requirement if you choose to use the 1992 version in any given period, it would not make any logical sense. Dependent upon product life cycle it would also not be logical to use the 1992 version if you were still to sell product after 2001-7-1. Note : although the forward of the specification states they have NO legal status as defined by the commission, these will be listed separately in the OJ - so until we see exactly what is written in the OJ it is all supposition !
