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.

INTRODUCTION


a) Technical background, main issues and organisation of the standard


This International Standard was prepared and based, to a very strong extent, on the current
application of the IEC 61000 series for commercial equipment qualification for

electromagnetic interference (EMI) and radio-frequency interference (RFI).


It is intended that this standard be used by operators of NPPs (utilities), systems evaluators

and by licensors.


b) Situation of the current standard in the structure of the SC 45A standard series
IEC 62003 is the third level SC 45A document dealing with the issue of qualification for
electromagnetic interference (EMI) and radio-frequency interference (RFI) applicable to I&C
systems important to safety in nuclear facilities.
For more details on the structure of the SC 45A standard series see item d) of this
introduction.
c) Recommendation and limitation regarding the application of this standard
It is important to note that this standard establishes no additional functional requirements for
safety systems but clarifies the criteria to be applied for qualification to EMI/RFI from the
commercial standards.
Aspects for which special requirements and recommendations have been produced, are:
1) IEC 61000 series with specific qualifications for nuclear applications around the world;
2) regulatory interpretations for requirements on level of qualification necessary and types of
recommended testing to address all potential environmental stressors, related to this type
of qualification;
3) IEC 61000-6-2, Electromagnetic compatibility (EMC) – Part 6-2: Generic Standards –
Immunity for industrial environments addresses requirements for all industrial
environments while this standard addresses environments in nuclear facilities specifically.
d) Description of the structure of the SC 45A standard series and relationships with
other IEC documents and other bodies documents (IAEA, ISO)
The top-level document of the IEC SC 45A standard series is IEC 61513. It provides general

requirements for I&C systems and equipment that are used to perform functions important to
safety in NPPs. IEC 61513 structures the IEC SC 45A standard series.
IEC 61513 refers directly to other IEC SC 45A standards for general topics related to
categorization of functions and classification of systems, qualification, separation of systems,
defence against common cause failure, software aspects of computer-based systems,
hardware aspects of computer-based systems, and control room design. The standards
referenced directly at this second level should be considered together with IEC 61513 as a
consistent document set.
At a third level, IEC SC 45A standards not directly referenced by IEC 61513 are standards
related to specific equipment, technical methods, or specific activities. Usually, these
documents, which make reference to second-level documents for general topics, can be used
on their own.
A fourth level extending the IEC SC 45A standard series, corresponds to the Technical
Reports which are not normative.

---------------------- Page: 8 ----------------------
62003 © IEC:2009 – 7 –


IEC 61513 has adopted a presentation format similar to the basic safety publication

IEC 61508 with an overall safety life-cycle framework and a system life-cycle framework and

provides an interpretation of the general requirements of IEC 61508-1, IEC 61508-2 and

IEC 61508-4, for the nuclear application sector. Compliance with IEC 61513 will facilitate

consistency with the requirements of IEC 61508 as they have been interpreted for the nuclear

industry. In this framework, IEC 60880 and IEC 62138 correspond to IEC 61508-3 for the

nuclear application sector.


IEC 61513 refers to ISO as well as to IAEA 50-C-QA (now replaced by IAEA GS-R-3) for

topics related to quality assurance (QA).


The IEC SC 45A standards series consistently implements and details the principles and
basic safety aspects provided in the IAEA code on the safety of NPPs and in the IAEA safety
series, in particular the Requirements NS-R-1, establishing safety requirements related to the
design of Nuclear Power Plants, and the Safety Guide NS-G-1.3 dealing with instrumentation
and control systems important to safety in Nuclear Power Plants. The terminology and
definitions used by SC 45A standards are consistent with those used by the IAEA.
