ELECTROMAGNETIC COMPATIBILITY OF MULTIMEDIA EQUIPMENT –
IMMUNITY REQUIREMENTS
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 35 has been prepared by CISPR subcommittee I:
Electromagnetic compatibility of information technology equipment, multimedia equipment and
receivers.
The text of this standard is based on the following documents:

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website 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.

INTRODUCTION
This CISPR document establishes uniform requirements for the electromagnetic immunity of
multimedia equipment. The test methods are given within this document or in referenced
basic EMC immunity standards. This document specifies applicable tests, test levels, product
operating conditions and assessment criteria.

ELECTROMAGNETIC COMPATIBILITY OF MULTIMEDIA EQUIPMENT –
IMMUNITY REQUIREMENTS
1 Scope
NOTE Blue coloured text within this document indicates text aligned with CISPR 32. CISPR 32 contains the
appropriate emission requirements above 150 kHz for the equipment within the scope of this document.
This document applies to multimedia equipment (MME) as defined in 3.1.24 and having a
rated AC or DC supply voltage not exceeding 600 V.
MME within the scope of CISPR 20 or CISPR 24 is within the scope of this document.
MME with a broadcast reception function is within the scope of this document, see Annex A.
MME with non-broadcast wireless interfaces is also within the scope of this document,
however, compliance with this document does not require the assessment of the performance
of these interfaces.
MME intended primarily for professional use is within the scope of this document.
MME for which immunity requirements in the frequency range covered by this document are
explicitly formulated in other CISPR documents (except CISPR 20 and CISPR 24) are
excluded from the scope of this document.
The objectives of this document are:
• to establish requirements which provide an adequate level of intrinsic immunity so that the
MME will operate as intended in its environment in the frequency range 0 kHz to 400 GHz;
• to specify procedures to ensure the reproducibility of tests and the repeatability of results.
Due to technology convergence of the functions of MME, the performance criteria have been
determined on a function-orientated basis rather than on an equipment-orientated basis.
