John,
We have bounced this subject around ad nauseam ("to the point of sickness"
for those not into latin).
As I understand it, the long and short of it is:
The writers of EN 61326-1 separated equipment into two classes. Class A and
Class B. They intended to exclude Class A equipment from the Harmonics and
Flicker requirements.
Problem is: according to how standards are "ranked". EN 61326-1 doesn't
have the "authority" to exclude equipment from EN 61000-3-2 and EN
61000-3-3. There are arguments that could last a lifetime regarding which
of the two standards should take precedence.
Actually, the path that I have taken is to assume that the Harmonic and
Flicker standards apply and then look at the application of EN 61000-3-2 and
EN 61000-3-3 themselves. Under EN 61000-3-2 and EN 61000-3-3 equipment must
be put into different classes depending upon how much power it draws and
whether or not the equipment is "professional" equipment. By looking at
these classifications, you can make an educated decision regarding whether
the standards apply or not.
If you want to draw your own conclusions, check out the online standards
update "Conformity-Update" put out by Curtis-Straus. There were some
articles in the August and September 2000 updates that cover a great deal of
this ground.

Happy hunting.

> compliance is mandatory for products consuming currents less than or equal

> distribution systems in the European Union.
>
> Is compliance on 1 January 2001 mandatory for products that will meet the
> EMC requirements defined in EN 61326 (electrical equipment for
> measurement,
> control and laboratory use) which has an effectivity date of 1 July 2001?
>
> Do participants in the group agree that testing is mandatory before
> 1 January 2001, and have they started/completed testing their products?
