This European Standard was approved by CENELEC on 2009-03-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 77B/574/FDIS, future edition 2 of IEC 61000-4-2, prepared by SC 77B, High
frequency phenomena, of IEC TC 77, Electromagnetic compatibility, was submitted to the IEC-CENELEC
parallel vote and was approved by CENELEC as EN 61000-4-2 on 2009-03-01.
This European Standard supersedes EN 61000-4-2:1995 + A1:1998 + A2:2001.
The main changes with respect to EN 61000-4-2:1995 are the following:
– the specifications of the target have been extended up to 4 GHz. An example of target matching these
requirements is also provided;
– information on radiated fields from human-metal discharge and from ESD generators is provided;
– measurement uncertainty considerations with examples of uncertainty budgets are given too.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2009-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-03-01
Annex ZA has been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 61000-4-2:2008 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following note has to be added for the standard indicated:
IEC 61000-6-1 NOTE  Harmonized as EN 61000-6-1:2007 (not modified).
