Re: EN (SPECIFIC )STANDARDS VS THE ~ EQUIVALENT IEC STANDARDS

[Monrad Monsen]

Whoops!  Good points made by Adam Rudd & Tom Sato.  They give valid support
for using the EN version standards in contrast to the IEC versions.  

I have the BS EN 55024:1998  CISPR 24:1997 incorporating Amendments Nos. 1 and
2.  This BSI version does not have an "Endorsement Notice", but I assume that
what your standard refers to as an "Endorsement Notice" is the same as what
BSI calls the "Foreword", and the foreword does state that Annex ZA has been
added by CENELEC and is normative.

I note that Annex ZA does specify which "international standards have been
modified by common modification" through the annotation of "(mod)". 
Therefore, in answer to Reginald Henry's original question regarding "if these
 specific standards below are one to one with the IEC Standard", the only
Information Technology Equipment (ITE) related standards listed that have the
"(mod)" marking are IEC61000-4-3 (radiated RF field immunity test) and CISPR22
(RF disturbance characteristics or RF emissions).  For these tests, it is
important to use the EN61000-4-3 and EN55022.  Of course, EN55022 is already
listed in the Official Journal as is EN55024, so EN55022 should not be a
surprise to anyone.  However, I'm going to have to order EN61000-4-3.

Thanks.

Monrad,

My copy, SS-EN 55024, has an Endorsement Notice on page 3 which lists

modifications CENELEC made to IEC CISPR 24 for the EN 55024 publication.

 

Additionally, it notes that CENELEC added Annex ZA.  Annex ZA is found

European and International standards which has this following note…

John,
I don't know what version of EN55024 you are looking at, but 
EN55024:1998
only references the IEC standards for each immunity test.  For example, Table
1 for enclosure port immunity lists the standard IEC 61000-4-2 for
Electrostatic Discharge.  In fact, all of the standards listed in the section
2 "Normative References" are IEC standards ... not EN standards.  This did not
change with amendments A1:2001 and A2:2003.

To Doug Kramer's point, it would be unwise to look for the EN61000-4-2
standard when EN55024 specifies use of the IEC61000-4-2 standard.

And CENELEC Guide 25 Annex 3 says:

   When there is a directly corresponding edition of CENELEC EN
   to the referred international standard and that international
   reference is dated, the annex ZA gives the indication of the
   corresponding CENELEC document (mostly EN) with its date.

   Remark: In this case, the dated edition of CENELEC EN applies
   (modified or not according to the case)

I think that is misleading on the part of CENELEC. While the technical 
requirements may be identical, there are other matters, notably the 
validity dates and the normative references, which are not the same. ENs 
have specific 'dop' and 'docopocoss' dates, among others, while IEC 
standard do not.

While for some purposes, those differences may not be significant, in 
other cases they can be.

RE: EN (SPECIFIC )STANDARDS VS THE ~ EQUIVALENT IEC STANDARDS

[Benoit Nadeau]

Bonjour Reginald,

 

The better place to go to get your answer is on the Cenelec web site on the
publish/in progress page

 

http://www.cenelec.eu/Cenelec/Code/Frameset.aspx

 

You then just put the reference on the standard you’re looking for in the
first block and click on run report:

 

For instance 61000-4-2 will give you a bunch of answers but the one you’re
looking for his the third last from the bottom (the first on the list is the
runner up)

 

If you click on any of them then you get all the details and especially if
this document is a direct copy of IEC or a modified version. In this
particular case they are identical. But if you try with en55022 for instance
you will see that this one has been modified from the CISPR version.

RE: EN (SPECIFIC )STANDARDS VS THE ~ EQUIVALENT IEC STANDARDS

[Doug Kramer]

Remember to keep in mind you may not care what the EN version of the IEC
says as the product family standards for your particular universe may
all reference the IEC versions.  If I recall correctly, there are no
more 61000-4 standards listed on the newappraoch.org website as
harmonized.  If EN 55024 calls out testing to IEC 61000-4-4, use of
EN61000-4-4 (what's the date on that?) would not be the correct
approach.

RE: EN (SPECIFIC )STANDARDS VS THE ~ EQUIVALENT IEC STANDARDS

[Glyn Garside]

I am not particularly familiar with those specific standards, but...
 
a) The national versions (BS EN, DIN EN, IS EN, etc.) editions should have the
same technical content as the EN (not IEC) version, except the language may
vary.
 
In any case the list of harmonized standards published by the EU lists only
the EN version.
 
b) The lists of harmonized standards published by the EU show the IEC
equivalence, and note whether it is modified. (Sorry, this won't help you,
because the standards you list are testing standards, not harmonized
standards, but I offer this as a useful tip for others.)
 
For EMC standards, see

http://ec.europa.eu/enterprise/newappro
ch/standardization/harmstds/reflist/emc.html
 
For example, the entry for EN 61000-6-2:2005 states, "(IEC 61000-6-2:2005)".
Whereas the entry for EN 61000-6-4:2001 states, "(IEC 61000-6-4:1997
(Modified)) "
 
c) Similarly, the BSI catalog/catalogue
  
http://www.bsi-global.com/en/Shop/Publication-Detail/?pid=0030043887
states for BS EN 61000-6-4:2001, "EN 61000-6-4:2001 Identical, IEC
61000-6-4:1997 Modified"

Subject: UL60950 vs. IEC 60950



Sorry if this has been asked before, but can anyone point me to a comparison
of these two standards, highlighting any significant differences? 

Is there any significant reason why compliance with UL60950 cannot be used to
show compliance with the LVD for CE marking? 

Any help appreciated, 

Best Regards,
Dave Coleman AIIRSM
