Re: EN 61000-3-2 Mandatory Implementation Dates?

1998-04-10 Thread Andy Griffin
I recently presented a paper on this subject, the commission has still not
listed anything in the OJ about the implementation dates.  

You can find the paper on line off the following page ! 

http://www.emisoft.co.uk/special/hotemc.htm

I do intend to keep this presentation up to date when/if the commission do
publish something ?

In the March/April issue of Compliance Engineering in an article about
harmonics measurements, there is mention of formal acceptance of a dow for
61000-3-2 of January 1, 2001.  This means that equipment which fell under
the scope of EN 60555-2, may continue to be tested to that (less
restrictive) standard until January 1, 2001.  However, unless I am missing
something it also means that products that did not fall under 60555-2, but
fall under the scope of 61000-3-2 (for example ITE) must immediately go
from no harmonic emissions requirement to having to comply with the most
restrictive 61000-3-2 requirements.  Or... is it an option to test these
products to 60555-2 until Jan. 1, 2001?  Does the original June 1, 1998 dow
have any meaning in this latest twist on the powerline emissions saga?  If
you have definitive information on this issue, please keep the EMC-PSTC

Re: EN 55022 ITE Class A vs. Class B?

1998-04-08 Thread Andy Griffin
EN55022 is currently the relevant product family specification, hence the
generic specification have no relevnace. EN55022 clearly states that class
B is for equipment intended primarily for the residential/domestic
environment and class A is for all other locations.  

Hence the Germany government [or any other] can not impose class B when
EN55022 states class A !  Yes there is the problem of home office type
situation but the specification does state primarily intended for home use !

What a manufacturer must be aware of is what are the demands of his customers.

If EN55022 changes or a different relevant specification is issued then
this situation may obviously change !

hello Tommy,


For ITE equipment you'd better perform to Class B, in the whole of the EU.
Class A is restricted to industrial locations only, and this is according to
the EMC-directive very limited area.

Garages, hospitals, offices and even standard light industry should be
classified acc. to B.


Difference between A and B is distance of testing. The limits for Class A
are valid at a testing distance of 30 meters, where Class B requires them to
be met at 10 meters.

I know that ITE can meet Class A ITE Limit.
The question is concerning European ITE EMI, Class A and B.

Has anyone had or have known of problems with a Class A ITE

I have heard that Germany is requiring Class B on all equipment

about a month later.  My understanding is that it takes six to nine months

Andy did a nice spoof on my objections to the abuse of language.  It so
happens
that I am dead serious about the fact that a large portion of the so-called
approval problems stem from the abuse of language committed by well-willing
engineers
in standards and regulations, by and large written by industry.

They believe that those who insist the accurate use of language, don't
understand the issues, or are trying to avoid the issues.  No doubt that
may be true in some cases, but my general experience is that this is not
pedantery and that they understand the issues a bit too well.

However, as many now know quite well, I do not take myself too serious and
recommend that nobody in this racket become too self rightuous.  Let's stop
doing this, if it isn't fun any longer and remember, behind every clown's
face is a sad person at heart.

RE: EN50082-1:1997

1998-01-12 Thread Andy Griffin
EN50082-1:1997 [BSEN50082-1:1998] includes the following dates:-

dop - 1998-3-1
dow - 2001-7-1

the forward make NO reference to products which have previously satisfied
1992 requirements.  Hence ALL products sold after this date [which need to
use the generics] must meet this requirement on 2001-7-1 [year-month-day].  

I will check back through my records but I do not remember any such
requirement if you choose to use the 1992 version in any given period, it
would not make any logical sense. Dependent upon product life cycle it
would also not be logical to use the 1992 version if you were still to sell
product after 2001-7-1.  

Note : although the forward of the specification states they have NO legal
status as defined by the commission, these will be listed separately in the
OJ - so until we see exactly what is written in the OJ it is all supposition !

As Scott correctly quoted from EN55022 (and CISPR 22 1993 edition),  If
the field strength measurement at 10 m cannot be made because of high
ambient noise levels or for other reasons, measurement of Class B EUTs
may be made at a closer distance, for example 3m.

It does not mention, or include class A, only B. Class A equipment must
be tested at 10 metres. When introduced, this was a fundamental change,
as this statement was not in previous versions of CISPR22. Some labs
choose to overlook it, particularly those having OATS with unacceptably
high ambients clouding the spectrum.

When all else fails, read the standard.

Keep in mind, the standards that you must test to for compliance with the
EMC Directive are those called out in a product or product family standard.
If none is published for your particular product, you must use the generic
immunity and emissions standards, which will then call out what test you
must do (as well as the levels you do the tests at, and the failure criteria).
