La CISPR 22:2008 est applicable aux appareils de traitement de l'information (ATI). Des procédures sont indiquées pour la mesure des niveaux des signaux parasites engendrés par les ATI; les limites sont spécifiées pour la gamme de fréquence de 9 kHz à 400 GHz et concernent aussi bien les appareils de classe A que ceux de classe B. Il n'est pas nécessaire d'effectuer de mesure aux fréquences pour lesquelles aucune limite n'est spécifiée. L'objet de la présente publication est d'établir des exigences uniformes pour les limites des perturbations radioélectriques des appareils relevant du domaine d'application, de fixer des limites pour le niveau perturbateur, de décrire des méthodes de mesure et de normaliser les conditions de fonctionnement et l'interprétation des résultats. Cette sixième édition de la CISPR 22 annule et remplace la cinquième édition parue en 2005, l'Amendement 1 (2005) et l'Amendement 2 (2006). Cette édition constitue une révision mineure. NEW! La CISPR 22:2008 est également disponible sous forme de IEC Standards+ CISPR 22:2008 qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
Oprema za informacijsko tehnologijo - Karakteristike občutljivosti za radijske motnje - Mejne vrednosti in merilne metode
Ta mednarodni standard velja za informacijsko tehnologijo (ITE), kot je opredeljeno v točki 3.1. Podani so postopki za merjenje ravni lažnih signalov, ki ji proizvede ITE, in opredeljene so mejne vrednosti za frekvenčni razpon od 9 kHz do 400 GHz za opremo razreda A in B. Kjer mejne vrednosti niso določene, ni potrebno nobeno merjenje. Namen te objave je vzpostaviti enotne zahteve za raven občutljivosti za radijske motnje pri opremi, zajeti na področjih uporabe, določiti mejne vrednosti občutljivosti, opisati metode merjenja ter standardizirati operativne pogoje in razlago rezultatov.

INTERPRETATION SHEET 1
This interpretation sheet has been prepared by CISPR subcommittee I: Electromagnetic
compatibility of information technology equipment, multimedia equipment and receivers, of
IEC technical committee CISPR: International special committee on radio interference.
The text of this interpretation sheet is based on the following documents:
ISH Report on voting
CISPR/I/299/ISH CISPR/I/312/RVD
Full information on the voting for the approval of this interpretation sheet can be found in the

Introduction:
th
At the CISPR SC I plenary, held on the 27 October 2007, a decision was taken to set the
maintenance date for CISPR 22, Edition 6 to 2012. As a result the work identified within
CISPR/I/279/MCR will not be started for the time being. At the subsequent meeting of CISPR
SC I WG3 it was decided that certain items within the MCR would benefit now from further
clarification and an interpretation sheet would be helpful to users of the standard, with the
intent of including this information in a future amendment to the standard.
This information does not change the standard; it serves only to clarify the points noted.
CISPR SC I WG3 hopes that these clarifications will be of use to users and especially
laboratories testing to CISPR 22, Edition 6.0. The document is based on the comments
received on CISPR/I/290/DC.
Interpretation:
1. Selection of Average detector
CISPR 22 defines limits for radiated emissions at frequencies between 1 GHz and 6 GHz with
respect to both average and peak detectors. CISPR 16-1-1 defines two types of Average
detector for use above 1 GHz. For the limits given in CISPR 22 the appropriate average
detector is the linear average detector defined in 6.4.1 of CISPR 16-1-1:2006 with its
Amendments 1:2006 and 2:2007.

2. Measurement of conducted emissions on cabinets containing multiple items of
equipment
Where the EUT is a cabinet or rack that contains multiple items of equipment that are
powered from an AC power distribution strip and where the AC power distribution strip is an
integral part of the EUT as declared by the manufacturer, the AC power line conducted
emissions should be measured on the input cable of power distribution strip that leaves the
cabinet or rack, not the power cables from the individual items of equipment. This is
consistent with the requirements in 9.5.1 paragraph 1 and sub paragraph c).

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.

Introduction:
th
At the CISPR SC I plenary, held on the 27 October 2007, a decision was taken to set the
maintenance date for CISPR 22, Edition 6 to 2012. As a result the work identified within
CISPR/I/279/MCR will not be started for the time being. At the subsequent meeting of CISPR
SC I WG3 it was decided that certain items within the MCR would benefit now from further
clarification and an interpretation sheet would be helpful to users of the standard, with the
intent of including this information in a future amendment to the standard.
This information does not change the standard; it serves only to clarify the points noted.
CISPR SC I WG3 hopes that these clarifications will be of use to users and especially
laboratories testing to CISPR 22, Edition 6.0. The document is based on the comments
received on CISPR/I/290/DC.
Interpretation:
1. Selection of Average detector
CISPR 22 defines limits for radiated emissions at frequencies between 1 GHz and 6 GHz with
respect to both average and peak detectors. CISPR 16-1-1 defines two types of Average
detector for use above 1 GHz. For the limits given in CISPR 22 the appropriate average
detector is the linear average detector defined in 6.4.1 of CISPR 16-1-1:2006 with its
Amendments 1:2006 and 2:2007.

2. Measurement of conducted emissions on cabinets containing multiple items of
equipment
Where the EUT is a cabinet or rack that contains multiple items of equipment that are
powered from an AC power distribution strip and where the AC power distribution strip is an
integral part of the EUT as declared by the manufacturer, the AC power line conducted
emissions should be measured on the input cable of power distribution strip that leaves the
cabinet or rack, not the power cables from the individual items of equipment. This is
consistent with the requirements in 9.5.1 paragraph 1 and sub paragraph c).

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
