Electromagnetic compatibility (EMC) - Part 4-12: Testing and measurement techniques - Ring wave immunity test
This part of IEC 61000 relates to the immunity requirements and test methods for electrical and electronic equipment, under operational conditions, to non-repetitive damped oscillatory transients (ring waves) occurring in low-voltage power, control and signal lines supplied by public and non-public networks. The object of this basic standard is to establish the immunity requirements and a common reference for evaluating in a laboratory the performance of electrical and electronic equipment intended for residential, commercial and industrial applications, as well as of equipment intended for power stations and substations, as applicable. The purpose of this standard is to define: - test voltage and current waveforms; - ranges of test levels; - test equipment; - test set-up; - test procedure.

La présente partie de la CEI 61000 traite des méthodes d'essai des matériels électriques et électroniques dans leurs conditions d'exploitation et des exigences en matière d'immunité contre les oscillations transitoires amorties non répétitives (ondes sinusoïdales amorties) se manifestant sur les alimentations basse tension ainsi que sur les lignes de commande et de signal raccordées aux réseaux publics ou privés. L'objet de cette norme fondamentale est d'établir les exigences d'immunité et de constituer une référence commune pour l'évaluation en laboratoire des performances d'équipements électriques et électroniques destinés aux applications résidentielles, commerciales et industrielles, ainsi que d'équipements destinés aux postes électriques et sous-stations, le cas échéant. La présente norme a pour objet de définir les paramètres suivants: - tension d'essai et formes d'ondes de courant; - gammes de niveaux d'essais; - matériel d'essai; - installation d'essai; - procédure d'essai.

ELECTROMAGNETIC COMPATIBILITY (EMC) –
Part 4-12: Testing and measurement techniques – Ring wave immunity test
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.
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 IEC 61000-4-12 has been prepared by subcommittee 77B: High frequency phenomena, of IEC technical Committee 77: Electromagnetic compatibility. It has the status of a basic EMC publication in accordance with IEC Guide 107, Electro-magnetic compatibility – Guide to the drafting of electromagnetic c
