RE: EN61000-3-2 +A14
Is the product a PC or is it some commercial product that just happens to have some processing capability? Consider the reason computers and TVs were included in the Class D list -- a large number of products put on the public power grid with significant harmonic heating. Then consider all of the exceptions -- products that are just as dirty but are low volume, therefore have minimal impact to the public power grid and are considered Class A. I believe that the product is defined by its market. If the product uses a computer as a portion of its design but is a commercial product (low volume), a case could be made for Class A. I strongly suggest anyone considering this route present this argument carefully to a Competent Body so as to provide justification in your files. My opinion only and not necessarily that of the Company.

Chris, If my memory serves me well, EN60555-2 required measurement of THD vs. complete/individual 40 harmonics' signature with individual limits required by -3-2.
