Part 1: General
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.

The text of this International Standard is based on the following documents:
FDIS Report on voting
9/2335/FDIS 9/2365/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, 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.

INTRODUCTION
The railway system EMC set series of product-specific International Standards consists of five
parts described at the end of this introduction.
The set series of standards provides both a framework for managing the EMC for railways
systems and also specifies the limits for the electromagnetic (EM) emission of the railway
system as a whole to the outside world and for the EM emission and immunity for equipment
operating within the railway system. The latter must is intended to be compatible with the
emission limits set for the railway system as a whole and also provides for establishing
confidence in equipment being fit for purpose in the railway environment. There are different
stationary emission limits set for trams/trolleybuses and for metro/mainline railways systems.
The frequency covered by the standards is in the range from DC to 400 GHz. No
measurements need to be performed at frequencies where no requirement is specified. The
limits for EMC phenomena are set so that the railway system as a whole achieves
electromagnetic compatibility with the outside world, and between the various parts of the
railway system. Throughout the set series of standards, the immunity levels are chosen to
ensure a reasonable level of EMC with other apparatus within the local railway environment
and with emissions which enter the railway system from the outside world. Limits are also
placed on EM emission by railways systems into the outside world.
The compatibility between railway system emissions and their external environment is based
upon emission limits from the railways systems being set by considering the results from
measurements. Given that the general compatibility between railways systems and their
environment was satisfactory at the time these measurements were made and subsequent
experience of applying the limits has confirmed their acceptability, compliance with this
document has been judged to give satisfactory compatibility. The immunity and emission
levels do
