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
the
modifications CENELEC made to IEC CISPR 24 for the EN 55024 publication.
Additionally, it notes that CENELEC added Annex ZA. Annex ZA is found
on
page 5. It lists the normative references and shows the correlation between
European and International standards which has this following note…
“NOTE: When an international publication has been modified by common
modifications, indicated by (mod), the relevant EN/HD applies.”
Does your copy have these sections?

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.

If EN 55024 calls out testing to IEC 61000-4-4, use of EN61000-4-4

I don't think there is any such case. All references in all EN Product
and
Generic standards are to the EN 61000-4-x.
