Electromagnetic compatibility (EMC) - Part 4-3 : Testing and measurement techniques - Radiated, radio-frequency, electromagnetic field immunity test

IEC 61000-4-3:2020 is applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. It establishes test levels and the required test procedures. The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to radiated, radio-frequency electromagnetic fields. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against RF electromagnetic fields from RF sources not in close proximity to the EUT. The test environment is specified in Clause 6. NOTE 1 As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. NOTE 2 Immunity testing against RF sources in close proximity to the EUT is defined in IEC 61000-4-39. Particular considerations are devoted to the protection against radio-frequency emissions from digital radiotelephones and other RF emitting devices. NOTE 3 Test methods are defined in this part for evaluating the effect that electromagnetic radiation has on the equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for quantitative determination of effects. The test methods defined in this basic document have the primary objective of establishing an adequate reproducibility of testing configuration and repeatability of test results at various test facilities. This document is an independent test method. It is not possible to use other test methods as substitutes for claiming compliance with this document. This fourth edition cancels and replaces the third edition published in 2006, Amendment 1:2007 and Amendment 2:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - testing using multiple test signals has been described; - additional information on EUT and cable layout has been added; - the upper frequency limitation has been removed to take account of new services; - the characterization of the field as well as the checking of power amplifier linearity of the immunity chain are specified.

Compatibilité électromagnétique (CEM) - Partie 4-3 : Techniques d'essai et de mesure - Essai d'immunité aux champs électromagnétiques rayonnés aux fréquences radioélectriques

IEC 61000-4-3:2020 traite des exigences d'immunité des matériels électriques et électroniques à l'énergie électromagnétique rayonnée. Elle définit les niveaux d'essai et les procédures d'essai exigés. Le présent document a pour objet d'établir une référence commune d'évaluation des performances en matière d’immunité des matériels électriques et électroniques soumis à des champs électromagnétiques aux fréquences radioélectriques. La méthode d'essai documentée dans la présente partie de l’IEC 61000 décrit une méthode cohérente d’évaluation de l'immunité d'un équipement ou d'un système aux champs électromagnétiques à fréquences radioélectriques générés par des sources de rayonnement aux fréquences radioélectriques qui ne se trouvent pas à proximité immédiate de l’EUT. L’environnement d’essai est spécifié à l’Article 6. NOTE 1 Comme cela est décrit dans le Guide IEC 107, cette publication est une publication fondamentale en CEM destinée à être utilisée par les comités de produits de l’IEC. Comme cela est également indiqué dans le Guide 107, les comités de produits de l’IEC sont responsables de déterminer s’il convient d’appliquer ou non la présente norme d’essai d’immunité et, si c’est le cas, ils sont responsables de déterminer les niveaux d’essai et les critères de performance appropriés. Le comité d’études 77 et ses sous-comités sont prêts à coopérer avec les comités de produits à l’évaluation de la valeur des essais d’immunité particuliers pour leurs produits. NOTE 2 Les essais d’immunité aux sources de rayonnement aux fréquences radioélectriques à proximité de l’EUT sont définis dans l’IEC 61000-4-39. Des considérations particulières sont consacrées à la protection contre les émissions aux fréquences radioélectriques des radiotéléphones numériques et d'autres dispositifs d'émission RF. NOTE 3 La présente partie définit des méthodes d'essai pour évaluer l'incidence des rayonnements électromagnétiques sur le matériel concerné. La simulation et le mesurage des rayonnements électromagnétiques ne sont pas suffisamment exacts pour déterminer quantitativement les effets. Les méthodes d'essai définies dans le présent document fondamental ont été principalement mises au point pour obtenir une bonne reproductibilité de la configuration des essais et une bonne répétabilité des résultats d’essai sur différentes installations d'essai. Le présent document présente une méthode d'essai indépendante. Il n'est pas possible d'utiliser d'autres méthodes d'essai comme variantes pour se conformer au présent document. Cette quatrième édition annule et remplace la troisième édition parue en 2006, l'Amendement 1:2007 et l'Amendement 2:2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente.
description des essais qui utilisent des signaux d’essai multiples;
ajout d’informations supplémentaires sur l’EUT et la disposition des câbles;
la limitation en matière de fréquences supérieures a été supprimée pour tenir compte des nouveaux services;
la caractérisation du champ ainsi que la vérification de la linéarité de l’amplificateur de puissance de la chaîne d'immunité sont spécifiées.
