The answers are: 1) Yes, and 2) Yes. 1) The original Cenelec press release is available in PDF format from the CENELEC web site, at http://www.cenelec.org/ . (Go to Press Release, then click on the link <12102000.PDF> Changes to the EMC standards are ratified.) Many thanks are due to Paul O'Shaughnessy for this information, which he shared with emc-pstc recently.
2) Other equipment that does not fall into the special classes B, C, or D, has to meet Class A. That is, unless it is declared by its manufacturer to be 'professional equipment' that is not sold to ordinary consumers - and it consumes over 1kW - in which case it has no limits to meet (yet) under 61000-3-2. Hope this clarifies the position.

For this reason, Working Group 1 of IEC SC 77A prepared an interim draft to address some of the standard's deficiencies. The draft modification proposes to withdraw the special wave-shape test for Class D yet still retains the Class D category and test limits. Equipment will be specified in the standard as being in the Class D category, and therefore have to be tested for compliance. PCs, PC monitors and television receivers with a power consumption of between 75 W and 600 W fall into this category. The vote closing date is 15 September 2000. If adopted, the Common Modification could be ratified before 1 January 2001. Manufacturers would have the option of using only the standard or using the standard with the Common Modification. There is no proposal to delay the date of withdrawal of EN 61000-3-2." > > Please help me clarify the followings: > (1) What is the vote result of 9/15/00? Has the Common Modification been adopted? > (2) If adopted, does it mean Class D only pertain to PC, PC monitors and TV? Does it mean there is no Class D category for other equipment? > > Thanks. > Best Regards, > Barry Ma <b...@anritsu.com> > ANRITSU www.anritsu.com > Morgan Hill, CA 95037 > Tel. 408-778-2000 x 4465 > _______________________________________________________________________ > > Free Unlimited Internet Access!
