This European Standard was approved by CENELEC on 2006-11-01. 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, 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 CISPR/A/657/FDIS, future edition 2 of CISPR 16-2-3, prepared by CISPR SC A,
Radio-interference measurements and statistical methods, was submitted to the IEC-CENELEC parallel
vote and was approved by CENELEC as EN 55016-2-3 on 2006-11-01.
This European Standard supersedes EN 55016-2-3:2004 + A1:2005 + A2:2005.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2007-08-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2009-11-01
with the EN have to be withdrawn
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard CISPR 16-2-3:2006 was approved by CENELEC as a European
Standard without any modification.
