Foreword
The text of document CISPR/A/798/FDIS, future edition 2 of CISPR 16-2-1, 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 55016-2-1 on 2009-03-01.
This European Standard supersedes EN 55016-2-1:2004 + A1:2005.
EN 55016-2-1:2009 includes significant technical changes with respect to EN 55016-2-1:2004. In general,
EN 55016-2-1:2009 aims at reducing compliance uncertainty in correspondence with findings in
CISPR 16-4-1. Guidelines are given on:
– resonance-free connection of the AMN to reference ground,
– avoidance of ground loops, and
– avoidance of ambiguities of the test setup of EUT and AMN with respect to the reference ground
plane.
In addition, terms are clarified, a new type of ancillary equipment (CVP) is applied, and a clarification for
the use of the AAN and AMN on the same EUT is provided.
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with the EN have to be withdrawn (dow) 2012-03-01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 CISPR 16-2-1:2008 was approved by CENELEC as a European
Standard without any modification.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the
