(Main)Electromagnetic compatibility (EMC) - Part 4-5: Testing and measurement techniques - Surge immunity test
Electromagnetic compatibility (EMC) - Part 4-5: Testing and measurement techniques - Surge immunity test
EN IEC 61000-4-5 relates to the immunity requirements, test methods, and range of recommended test levels for equipment with regard to unidirectional surges caused by overvoltages from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to surges. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against a defined phenomenon. This standard defines: - a range of test levels; - test equipment; - test setups; - test procedures. The task of the described laboratory test is to find the reaction of the equipment under test (EUT) under specified operational conditions to surge voltages caused by switching and lightning effects. It is not intended to test the capability of the EUT's insulation to withstand high-voltage stress. Direct injections of lightning currents, i.e. direct lightning strikes, are not considered in this standard.

Compatibilité électromagnétique (CEM) - Partie 4-5: Techniques d'essai et de mesure - Essai d'immunité aux ondes de choc
L'IEC 61000-4-5:2014 se rapporte aux exigences d'immunité pour les matériels, aux méthodes d'essai et à la gamme des niveaux d'essai recommandés, vis-à-vis des ondes de choc unidirectionnelles provoquées par des surtensions dues aux transitoires de foudre et de man uvre. Elle définit plusieurs niveaux d'essai se rapportant à différentes conditions d'environnement et d'installation. Ces exigences sont développées pour les matériels électriques et électroniques et leur sont applicables. Cette norme a pour objet d'établir une référence commune dans le but d'évaluer l'immunité des matériels électriques et électroniques, quand ils sont soumis à des ondes de choc. La méthode d'essai documentée décrit une méthode cohérente en vue d'évaluer l'immunité d'un matériel ou d'un système vis-à-vis d'un phénomène défini. La présente norme définit:
- une gamme de niveaux d'essai;
- le matériel d'essai;
- les montages d'essai; et
- les procédures d'essai. L'essai de laboratoire décrit ici a pour but de déterminer la réaction du matériel en essai (EUT), dans des conditions opérationnelles spécifiées, aux surtensions dues à la foudre ou à des manoeuvres. Il n'est pas destiné à évaluer la capacité de l'isolation de l'EUT à supporter des tensions élevées. Les injections directes de courants de foudre, par exemple les coups de foudre directs, ne sont pas prises en compte par la présente norme. Cette troisième édition annule et remplace la deuxième édition publiée 2005, et constitue une révision technique qui inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- une nouvelle Annexe E sur la modélisation mathématique des formes d'ondes de choc;
- une nouvelle Annexe F sur les incertitudes de mesure;
- une nouvelle Annexe G sur la méthode d'étalonnage des systèmes de mesure d'impulsion; et
- une nouvelle Annexe H sur les ondes de choc de couplage/découplage appliquées à des lignes de valeurs assignées supérieures à 200 A. De plus, alors que l'essai à l'onde de choc sur les accès connectés à des lignes de télécommunication extérieures était traité dans le 6.2 de la deuxième édition (IEC 61000-4-5:2005), dans cette troisième édition (IEC 61000-4-5:2014), l'Annexe normative A est complètement dédiée à ce sujet. En particulier elle donne les spécifications du générateur d'onde combinée 10/700 µs.

Elektromagnetna združljivost (EMC) - 4-5. del: Preskusne in merilne tehnike - Preskus odpornosti proti napetostnemu udaru (IEC 61000-4-5:2014)
Standard EN IEC 61000-4-5 obravnava zahteve po odpornosti, preskusne metode in razpon priporočenih preskusnih vrednosti za opremo glede na enosmerne napetostne udare, ki jih povzroči prenapetost pri prehodnem preklapljanju in atmosferskih napetostnih udarih. Določenih je več preskusnih ravni, ki se nanašajo na različna okolja in pogoje vgradnje. Te zahteve so oblikovane in veljajo za električno in elektronsko opremo. Namen tega standarda je določiti skupno referenco za ocenjevanje odpornosti električne in elektronske opreme na napetostne udare. Preskusna metoda, dokumentirana v tem delu standarda IEC 61000, opisuje skladno metodo za oceno odpornosti opreme ali sistema proti opredeljenemu pojavu. Ta standard določa: – razpon preskusnih ravni, – preskusno opremo, – preskusne nastavitve, – preskusne postopke. Naloga opisanega laboratorijskega preskusa je odkriti reakcijo preskušane opreme (EUT) pri določenih pogojih delovanja na napetostne udare, ki jih povzročita prehodno preklapljanje in atmosferski napetostni udari. Ni namenjen preskušanju odpornosti izolacije preskušane opreme na visokonapetostne obremenitve. Neposredno napajanje s tokovi strele, tj. neposredni udarci strele, niso obravnavani v tem standardu.

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.
