Railway applications - Electromagnetic compatibility - Part 5: Emission and immunity of fixed power supply installations and apparatus

IEC 62236-5:2018 applies to emission and immunity aspects of EMC for electrical and electronic apparatus and systems intended for use in railway fixed installations for power supply. This includes the power feed to the apparatus, the apparatus itself with its protective control circuits, trackside items such as switching stations, power autotransformers, booster transformers, substation power switchgear and power switchgear to other longitudinal and local supplies. This new edition includes the following significant technical changes with respect to the previous edition: clarification of certain parts of the standard; extension of emission and immunity requirements.

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.
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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

– 4 – IEC 62236-5:2018 RLV  IEC 2018
International Standard IEC 62236-5 has been prepared by IEC technical committee 9:
Electrical equipment and systems for railways.
This third edition cancels and replaces the second edition published in 2008. It constitutes a
technical revision and has been developed on the basis of EN 50121-5:2015.
This edition includes the following significant technical changes with respect to the previous
edition:
a) clarification of scope (Clause 1);
b) emission requirement extended in the frequency range 1 GHz to 6 GHz following
IEC 61000-6-4;
c) immunity requirement extended in the frequency range 5,1 GHz to 6 GHz;
d) removal of limits for radiated H-fields in the frequency range 9 kHz to 150 kHz due to the
fact that:
– there are very few outside world victims;
– there is low reproducibility.
This Standard is to be read in conjunction with IEC 62236-1.
The text of this International Standard is based on the following documents:
FDIS Report on voting
9/2340/FDIS 9/2370/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 62236 series, published under the general title Railway
applications – Electromagnetic compatibility, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.

INTRODUCTION
The requirements of this part of IEC 62236 have been specified so as to ensure a level of
electromagnetic emission which will cause minimal disturbance to other equipment. The
levels, however, do not cover the following cases:
a) where the probability of an occurrence likely to produce emissions in excess of those
which would normally be experienced is extremely low,
a) which may occur with an extremely low probability of occurrence in any location;
b) where highly susceptible apparatus will be is used in close proximity of the equipment
covered by this document, in which case further measures may have to be taken.
The emission limits given are on the basis that the equipment of the product family range is
installed in railway traction substation areas.
