CISPR 32:2012

Electromagnetic compatibility of multimedia equipment - Emission requirements

CISPR 32:2012 International Standard applies to multimedia equipment (MME) having a rated r.m.s. AC or DC supply voltage not exceeding 600 V. Equipment within the scope of CISPR 13 or CISPR 22 is within the scope of this publication. MME intended primarily for professional use is within the scope of this publication. The radiated emission requirements in this standard are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions. Equipment, for which emission requirements in the frequency range covered by this publication are explicitly formulated in other CISPR publications (except CISPR 13 and CISPR 22), are excluded from the scope of this publication. This document does not contain requirements for in-situ assessment. Such testing is outside the scope of this publication and may not be used to demonstrate compliance with it. This publication covers two classes of MME (Class A and Class B). The objectives of this publication are to establish requirements which provide an adequate level of protection of the radio spectrum, allowing radio services to operate as intended in the frequency range 9 kHz to 400 GHz and to specify procedures to ensure the reproducibility of measurement and the repeatability of results. The contents of corrigendum of March 2012 and August 2012 have been included in this copy.

Compatibilité électromagnétique des équipements multimédia - Exigences d'émission

La CISPR 32:2012 est une Norme Internationale qui s'applique aux équipements multimédia (MME) dont la tension d'alimentation efficace assignée en courant continu ou alternatif ne dépasse pas 600 V. Les équipements couverts par la CISPR 13 ou la CISPR 22 entrent dans le domaine d'application de cette publication. Les MME principalement destinés à une utilisation professionnelle entrent dans le domaine d'application de cette publication. Les exigences relatives aux émissions rayonnées stipulées dans la présente norme ne s'appliquent ni aux transmissions intentionnelles à partir d'un radio transmetteur comme défini par l'UIT, ni aux émissions liées à ces transmissions intentionnelles. Les équipements pour lesquels les exigences d'émission dans la gamme de fréquences couvertes par cette publication sont explicitement formulées dans d'autres publications CISPR (sauf la CISPR 13 et la CISPR 22), sont exclus du domaine d'application de cette publication. Le présent document ne contient pas d'exigences pour les évaluations in situ. Ce type d'essai est en dehors du domaine d'application de cette publication et n'est pas supposé être utilisé pour en démontrer la conformité. Cette publication couvre deux classes de MME (Classe A et Classe B). Les objectifs de cette publication sont d'établir des exigences qui fournissent un niveau suffisant de protection du spectre radio, permettant ainsi aux services radio d'opérer comme prévu dans la gamme de fréquences 9 kHz - 400 GHz et de spécifier les méthodes pour garantir la reproductibilité des mesures et la répétabilité des résultats. Le contenu des corrigendum de mars 2012 et août 2012 a été pris en considération dans cet exemplaire.

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.
International Standard CISPR 32 has been prepared by CISPR subcommittee I:

1 Scope
NOTE Blue coloured text within this document indicates text aligned with CISPR 35.
This International Standard applies to multimedia equipment (MME) as defined in 3.1.23 and
having a rated r.m.s. AC or DC supply voltage not exceeding 600 V.
Equipment within the scope of CISPR 13 or CISPR 22 is within the scope of this publication.
MME intended primarily for professional use is within the scope of this publication.
The radiated emission requirements in this standard are not intended to be applicable to the
intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious
emissions related to these intentional transmissions.
Equipment, for which emission requirements in the frequency range covered by this
publication are explicitly formulated in other CISPR publications (except CISPR 13 and
CISPR 22), are excluded from the scope of this publication.
This document does not contain requirements for in-situ assessment. Such testing is outside
the scope of this publication and may not be used to demonstrate compliance with it.
This publication covers two classes of MME (Class A and Class B). The MME classes are
specified in Clause 4.
The objectives of this publication are:
1) to establish requirements which provide an adequate level of protection of the radio
spectrum, allowing radio services to operate as intended in the frequency range 9 kHz to
400 GHz;
2) to specify procedures to ensure the reproducibility of measurement and the repeatability of
results.
