No one is forcing anyone to use Class D. Standards are voluntary. As I
reported a few days ago, we have a product that will not pass Class D but
will pass Class A. Our Notified Body told us that they will accept prA14, so
we are submitting a TCF for that standard and using Class A..

Subject: RE: Harmonics and the 600W limit
Hello List,
Is this a reasonable expectation - that the EC and member countries
will
actually move quickly enough to make A14 effective on January 1,
2001? Is
everyone going to be forced to meet EN 61000-3-2 without A14?

max power

normal

conditions
