IEC 61000-4-22:2010

Electromagnetic compatibility (EMC) - Part 4-22: Testing and measurement techniques - Radiated emissions and immunity measurements in fully anechoic rooms (FARs)

IEC 61000-4-22:2010 considers immunity tests and emission measurements for electric and/or electronic equipment. Only radiated phenomena are considered. It establishes the required test procedures for using fully anechoic rooms for performing radiated immunity testing and radiated emission measurements. IEC 61000-4-22:2010 establishes a common validation procedure, equipment under test (EUT) set-up requirements, and measurement methods for fully anechoic rooms (FARs) when both radiated electromagnetic emission measurements and radiated electromagnetic immunity tests will be performed in the same FAR. As a basic measurement standard, this part of IEC 61000 does not intend to specify the test levels or emission limits to be applied to particular apparatus or system(s). Its main goal is to provide general measurement procedures to all concerned product committees of IEC or CISPR. Specific product requirements and test conditions are defined by the responsible product committees. The methods described in this standard are appropriate for radiated emission measurements and immunity tests in the frequency range of 30 MHz to 18 GHz. IEC 61000-4-22:2010 has the status of a basic EMC publication in accordance with IEC Guide 107, Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications.

Compatibilité électromagnétique (CEM) - Partie 4-22: Techniques d'essai et de mesure - Mesures de l'immunité et des émissions rayonnées dans des enceintes complètement anéchoïques (FAR)

La CEI 61000-4-22:2010 couvre les essais d'immunité et les mesures d'émissions d'équipements électriques et/ou électroniques. Seuls les phénomènes rayonnés sont pris en compte. Elle définit les procédures d'essai requises pour l'utilisation d'enceintes complètement anéchoïques de mesure de l'immunité aux rayonnements et des émissions rayonnées. La CEI 61000-4-22:2010 établit une procédure de validation commune, les exigences de montage du matériel en essai (EUT) ainsi que les méthodes de mesure pour les enceintes complètement anéchoïques (FAR) lorsque les émissions électromagnétiques rayonnées et l'évaluation de l'immunité électromagnétique rayonnée sont mesurées dans la même enceinte FAR. En tant que norme de mesure de base, la présente partie de la CEI 61000 n'a pas pour but de spécifier les niveaux d'essai ou des limites d'émission à appliquer à un matériel ou système(s) particulier(s). Son principal objectif est de fournir des procédures de mesure d'ordre général à l'ensemble des comités de produits concernés de la CEI ou du CISPR. Les exigences et conditions d'essai applicables à un produit spécifique relèvent de la responsabilité des comités de produits concernés. Les méthodes décrites dans la présente norme permettent de mesurer les émissions rayonnées et l'immunité dans la gamme de fréquences de 30 MHz à 18 GHz. La CEI 61000-4-22:2010 a le statut de publication fondamentale en CEM conformément au Guide 107 de la CEI, Compatibilité électromagnétique - Guide pour les projets de publications en compatibilité électromagnétique.

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
