SPECIFICATION FOR RADIO DISTURBANCE AND

Part 1-4: Radio disturbance and immunity measuring apparatus –
Antennas and test sites for radiated disturbance measurements

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights
This fourth edition cancels and replaces the third edition published in 2010, Amendment 1:2012
and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• provisions are added to address test site validation in the frequency range from 30 MHz to
1000 MHz using the reference site method, to take into account the receive antenna
radiation pattern in the frequency range from 1 GHz to 18 GHz, and further details on test
site validation using the NSA method with broadband antennas in the frequency range from
30 MHz to 1 000 MHz.
CISPR 16-1-4:2019  IEC 2019 – 9 –
International Standard CISPR 16-1-4 has been prepared by CISPR subcommittee A: Radio-
interference measurements and statistical methods.
It has the status of a basic EMC publication in accordance with IEC Guide 107,
Electromagnetic compatibility – Guide to the drafting of electromagnetic compatibility
publications.
The text of this International Standard is based on the following documents:
FDIS Report on voting
CIS/A/1262/FDIS CIS/A/1275/RVD

Full information on the voting for the approval of this International Standard can be found in the
report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of CISPR 16 series, under the general title Specification for radio disturbance
and immunity measuring apparatus and methods, can be found on the IEC website.
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this document using a colour printer.

Antennas and test sites for radiated disturbance measurements

1 Scope
This part of CISPR 16 specifies the characteristics and performance of equipment for the
measurement of radiated disturbances in the frequency range 9 kHz to 18 GHz. Specifications
for antennas and test sites are included.
NOTE In accordance with IEC Guide 107, CISPR 16-1-4 is a basic EMC publication for use by product committees
of the IEC. As stated in Guide 107, product committees are responsible for determining the applicability of the EMC
