Hi all,
If you remember,
A while back, there was a thread in which I was involved regarding the
application of EN 61000-3-2 (Harmonics) and EN 61000-3-3 (Flicker) to
equipment covered by EN 61326-1 (test and measurement equipment). I have
kept all of the emails in a folder and have tallied the following
information:
- 2 people who believe that, since EN 61000-3-2 and EN 61000-3-3 are Product
Family standards, EN 61326-1 cannot treat them as Basic Standards and
"exempt" its Class A equipment from them.
- 1 person who believes that EN 61326-1 specifically intended to exempt its
class A equipment from the Harmonics and Flicker standards.
- 1 person who actually helped to write EN 61326-1 who states that the
authors of the standard did intend to exempt Class A equipment from
Harmonics and Flicker. Thus, (in his opinion) people complying to EN
61326-1 Class A emissions requirements are on solid footing if they ignore
Harmonics and Flicker. (Same opinion as above, but with some more
credibility.)
- 1 person who claims that EN 61000-3-2 and EN 61000-3-3 were changed from
Basic Standards to Product Family standards by a stroke of the editor's pen
without any furthur voting by CENELEC, thus causing conflict and confusion.
(This wasn't my opinion, but I'm believing it more and more every day.)
- 1 person who claims that, depending on the notified body, some may
interpret the EU's "Essential Requirements" to mandate Harmonics and Flicker
testing regardless of what other standards apply to a product.
To me, this was very confusing. So I went to CENELEC's website
(www.cenelec.be) and asked the question to them via an information request.
I received a reply about a day later referring me to the American National
Standards Institute (ANSI).
So, I dutifully took this question to ANSI (via email). I have received no
reply since.
I guess that I have learned first hand how we are left to interpret an issue
that I believe could be very clearly defined.
In concluding, I cannot tell anyone to pick any of the above statements over
the others. They all have their merits in my eyes. I tried to short
circuit the interpretation and get some information from the source to no
avail.
Does anybody else care to comment?
