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.

INTRODUCTION
a) Technical background, main issues and organization 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 compatibility (EMC).

It is intended that this standard be used by operators of nuclear power plants (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 compatibility (EMC) applicable to Instrumentation and Control (I&C) and

electrical 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
Electromagnetic and Radio Frequency Interference (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.

This standard is intended to align with the guidance contained within IEC 61000-6-5 and

IEC 61000-6-7 where possible. Additional considerations from these standards can be

used in conjunction with this standard when addressing the EMC of electrical and I&C

equipment in nuclear facilities.

d) Description of the structure of the IEC SC45A standard series and relationships with

other IEC documents and other bodies documents (IAEA, ISO)

The top-level documents of the IEC SC45A standard series are IEC 61513 and IEC 63046.

IEC 61513 provides general requirements for I&C systems and equipment that are used to

perform functions important to safety in NPPs. IEC 63046 provides general requirements

for electrical power systems of NPPs; it covers power supply systems including the supply

systems of the I&C systems. IEC 61513 and IEC 63046 are to be considered in

conjunction and at the same level. IEC 61513 and IEC 63046 structure the IEC SC45A

standard series and shape a complete framework establishing general requirements for

instrumentation, control and electrical systems for nuclear power plants.

IEC 61513 and IEC 63046 refer directly to other IEC SC45A standards for general topics

related to categorization of functions and classification of systems, qualification,

separation, defence against common cause failure, control room design, electromagnetic

compatibility, cybersecurity, software and hardware aspects for programmable digital

systems, coordination of safety and security requirements and management of ageing.

The standards referenced directly at this second level should be considered together with

IEC 61513 and IEC 63046 as a consistent document set.
At a third level, IEC SC45A standards not directly referenced by IEC 61513 or by

IEC 63046 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.
---------------------- Page: 8 ----------------------
IEC 62003:2020 © IEC 2020 – 7 –

A fourth level extending the IEC SC45 standard series, corresponds to the Technical

Reports which are not normative.

The IEC SC45A standards series consistently implements and details the safety and

security principles and basic aspects provided in the relevant IAEA safety standards and

in the relevant documents of the IAEA nuclear security series (NSS). In particular this

includes the IAEA requirements SSR-2/1, establishing safety requirements related to the

design of nuclear power plants (NPPs), the IAEA safety guide SSG-30 dealing with the

safety classification of structures, systems and components in NPPs, the IAEA safety

guide SSG-39 dealing with the design of instrumentation and control systems for NPPs,

the IAEA safety guide SSG-34 dealing with the design of electrical power systems for

NPPs and the implementing guide NSS17 for computer security at nuclear facilities. The

safety and security terminology and definitions used by SC45A standards are consistent

with those used by the IAEA.

IEC 61513 and IEC 63046 have adopted a presentation format similar to the basic safety

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

framework. Regarding nuclear safety, IEC 61513 and IEC 63046 provide the interpretation

of the general requirements of IEC 61508-1, IEC 61508-2 and IEC 61508-4, for the
nuclear application sector. In this framework IEC 60880, IEC 62138 and IEC 62566

correspond to IEC 61508-3 for the nuclear application sector. IEC 61513 and IEC 63046

refer to ISO as well as to IAEA GS-R part 2 and IAEA GS-G-3.1 and IAEA GS-G-3.5 for

topics related to quality assurance (QA). At level 2, regarding nuclear security, IEC 62645

is the entry document for the IEC/SC45A security standards. It builds upon the valid high

level principles and main concepts of the generic security standards, in particular ISO/IEC

27001 and ISO/IEC 27002; it adapts them and completes them to fit the nuclear context

and coordinates with the IEC 62443 series. At level 2, IEC 60964 is the entry document for

the IEC/SC45A control rooms standards and IEC 62342 is the entry document for the

ageing management standards.

NOTE 1 It is assumed that for the design of I&C systems in NPPs that implement conventional safety

functions (e.g. to address worker safety, asset protection, chemical hazards, process energy hazards)

international or national standards would be applied.

NOTE 2 IEC/SC45A domain was extended in 2013 to cover electrical systems. In 2014 and 2015 discussions

were held in IEC/SC45A to decide how and where general requirements for the design of electrical systems

were to be considered. IEC/SC45A experts recommended that an independent standard be developed at the

same level as IEC 61513 to establish general requirements for electrical systems. Project IEC 63046 is now

launched to cover this objective. When IEC 63046 is published this NOTE 2 of the introduction of IEC/SC45A

standards will be suppressed.

NUCLEAR POWER PLANTS – INSTRUMENTION, CONTROL
AND ELECTRICAL POWER SYSTEMS – REQUIREMENTS
FOR ELECTROMAGNETIC COMPATIBILITY TESTING
1 Scope

This document establishes requirements for electromagnetic compatibility testing of

instrumentation, control, and electrical equipment supplied for use in systems important to

safety at nuclear power plants and other nuclear facilities. The document 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.

The normative part of this document is limited to the testing of equipment prior to installation

in a nuclear power plant to demonstrate immunity to electromagnetic disturbances and to

demonstrate that the equipment does not generate excessive emissions. Testing for the

generation of excessive emissions is also applicable to non-safety equipment. This document

includes informative annexes which provide additional guidance and describes approaches to

maintaining electromagnetic compatibility for installed equipment. The intent of this document

is to provide guidance for conducting the electromagnetic compatibility (EMC) qualification

testing of the equipment and does not provide guidance for the installation of the equipment

to prevent electromagnetic and radio frequency interference (EMI/RFI). However, the

configuration of the equipment under test during EMC qualification testing is representative of

the intended installation in a nuclear facility.
Protection against a high altitude electromagnetic pulse (HEMP) and intentional

electromagnetic interference (IEMI) are outside of the scope of this document, but information

can be found in IEC 61000-4-23, IEC 61000-4-24, and IEC 61000-4-25 (HEMP) and
IEC 61000-4-36 (IEMI) to address these phenomena.
