IEC 62003:2009

Nuclear power plants - Instrumentation and control important to safety - Requirements for electromagnetic compatibility testing

IEC 62003:2009 establishes requirements for electromagnetic compatibility testing of instrumentation and control equipment supplied for use in systems important to safety at nuclear power plants. Lists the applicable IEC standards (principally the IEC 61000 series) which define the general test methods, and provides the necessary application-specific parameters and criteria to ensure that nuclear safety requirements are met.

Centrales nucléaires de puissance - Instrumentation et contrôle- commande importants pour la sûreté - Exigences relatives aux essais de compatibilité électromagnétique

La CEI 62003:2009 établit des exigences pour les essais de compatibilité électromagnétique du matériel d'instrumentation et de contrôle-commande (I&C) utilisé dans les systèmes importants pour la sûreté dans les centrales nucléaires de puissance. La norme donne la liste des normes CEI applicables (principalement la série CEI 61000) qui définissent les méthodes d'essais générales, et fournit les paramètres propres à l'application ainsi que les critères nécessaires pour garantir que les exigences de sûreté nucléaires sont satisfaites.

REQUIREMENTS FOR ELECTROMAGNETIC COMPATIBILITY TESTING

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
