In Japan: 57 dB(µV/m) is relaxed to 66 dB(µV/m) for operating channels <300 MHz and to 70 dB(µV/m) for
operating channels >300 MHz.
b
The RMS-average limits can be applied as an alternative to quasi-peak limits.
c For narrowband disturbances 40 dB(µV/m) applies. For this application a narrowband disturbance is
identified if the difference between Peak and RMS-average value is ≤ 3 dB. All other signals are
considered as broadband disturbances. For these signals a Peak limit of 54 dB(µV/m) applies in addition
to the RMS-average limit of 34 dB(µV/m).

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 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.
International Standard CISPR 13 has been prepared by CISPR subcommittee I:
Electromagnetic compatibility of information technology equipment, multimedia equipment and
receivers.
This fifth edition of CISPR 13 cancels and replaces the fourth edition published in 2001, its
Amendment 1 (2003) and Amendment 2 (2006).This edition constitutes the introduction of the
RMS-average detector as an alternative to quasi-peak and average detector for conducted and
radiated emission measurements.
The document CISPR/I/296/FDIS, circulated to the National Committees as Amendment 3, led
to the publication of the new edition.

The committee has decided that the contents of this publication will remain unchanged until the

INTRODUCTION
The CISPR recommends that the limits and methods of measurement of radio disturbance
characteristics of sound and television receivers contained in the latest edition of CISPR 13,
including amendments, be used, without regional or national addenda or modifications. The
requirements are considered sufficient to reach adequate emission levels to protect radio
broadcast and telecommunication services and to allow other apparatus to operate as intended
at a reasonable distance.

LIMITS AND METHODS OF MEASUREMENT

1 Scope and object
This International Standard applies to the generation of electromagnetic energy from sound
and television receivers for the reception of broadcast and similar transmissions and from
associated equipment. The frequency range covered extends from 9 kHz to 400 GHz.
No measurements need be performed at frequencies where no limits are specified.
Receiving systems for collective reception, in particular:
– cable distribution head ends (Community Antenna Television, CATV);
– community reception systems (Master Antenna Television, MATV)
are covered by IEC 60728-2.
Broadcast receivers for digital signals are covered by Annex A and Annex B.
Information technology equipment (ITE) is excluded, even if intended to be connected to a
television broadcast receiver.
The telecommunication port of broadcast receivers, intended to be connected to a tele-
communication network, is covered by CISPR 22.
In addition, measurements at the telecommunication port are performed with the broadcast
reception functions, which are independent from the telecommunication function, disabled
during the measurement.
PC tuner cards are measured according to the relevant clauses of this standard.
This standard describes the methods of measurement applicable to sound and television
receivers or associated equipment and specifies limits for the control of disturbance from such
equipment.
For multifunction equipment which is subjected simultaneously to different clauses of this
standard and/or other standards, details are given in 4.1.

and/or other standards shall be tested with each function operated in isolation, if this can
be achieved without modifying the equipment internally. The equipment thus tested shall be
deemed to have complied with the requirements of all clauses/standards when each function
has satisfied the requirements of the relevant clause/standard.
For equipment for which it is not practical to test with each function operated in isolation, or
where the isolation of a particular function would result in the equipment being unable to fulfil
its primary function, the equipment shall be deemed to have complied if it meets the provisions
of the relevant clause/standard with the necessary functions operative.

limits for the measurements with the average detector are considered to be met.
NOTE 2 The higher value measured with and without the outer conductor screen of the antenna terminal connected
to earth is considered.
NOTE 3 Television receivers with teletext facilities should be tested in teletext mode with teletext picture.

4.3 Disturbance voltage at the antenna terminals
Measurements of the antenna terminal voltage shall be made in accordance with 5.4.
The limit values specified correspond to a nominal impedance of 75 Ω.
The limit values for receivers with nominal impedance other than 75 Ω are calculated according
to the following formula:
L = L + 10 log (Z/75) dB(μV)

4.4 Wanted signal and disturbance voltage at the RF output of equipment with
incorporated or with add-on RF video modulator
Measurements of the wanted signal and disturbance voltage at the RF output terminals of
equipment with incorporated or with add-on RF video modulator (e.g. of video recorders and
