IEC 62236-4:2008

Railway applications - Electromagnetic compatibility - Part 4: Emission and immunity of the signalling and telecommunications apparatus

IEC 62236-4:2008 specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications apparatus which may interfere with other apparatus in the railway environment, or increase the total emissions for the railway environment beyond the limits defined in the appropriate standard and so risk causing electromagnetic interference to apparatus outside the railway system. The main change with respect to the previous edition consists of the requirements for the radiated immunity test.

Applications ferroviaires - Compatibilité électromagnétique - Partie 4: Emission et immunité des appareils de signalisation et de télécommunication

La CEI 62236-4:2008 spécifie les limites d'émission et d'immunité et donne les critères d'aptitude à la fonction pour les appareils de signalisation et de télécommunication qui peuvent perturber d'autres appareils dans l'environnement ferroviaire ou augmenter les émissions totales pour l'environnement ferroviaire au-delà des limites définies dans la norme appropriée et qui risquent ainsi d'être la cause d'un brouillage électromagnétique pour des appareils à l'extérieur du système ferroviaire. Les modification principales par rapport à l'édition précédente concernent les exigences pour l'essai d'immunité rayonnée.

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.

International Standard IEC 62236-4 has been prepared by IEC technical committee 9:
Electrical equipment and systems for railways.
This second edition cancels and replaces the first edition published in 2003. It constitutes a
technical revision and is based on EN 50121-4:2006.
The main changes with respect to the previous edition are listed below:
– requirements for the radiated immunity test of line 1.2 in Table 1;
– suppression of annex A.

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

Electromagnetic compatibility, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in

INTRODUCTION
This part of IEC 62236 has been prepared in the form of a product standard.

It defines the immunity and emission test requirements for apparatus defined in the scope in
relation to the electromagnetic disturbances likely to be experienced in the railway. In

particular, the test requirements represent the essential electromagnetic immunity

requirements and have been selected to ensure an adequate level of immunity for apparatus

installed in the railway locations.

Test requirements are specified for each port considered.

Safety considerations are not covered by this standard.
In special situations, where the level of disturbances may exceed the levels considered in this
standard, for example at a special location or where a hand-held transmitter is used in very
close proximity to an apparatus, special mitigation measures may be necessary.

Part 4: Emission and immunity of the signalling

and telecommunications apparatus

1 Scope
This part of IEC 62236 applies to signalling and telecommunication apparatus which is
installed in the railway environment. Signalling and telecommunication apparatus mounted in
vehicles is covered by IEC 62236-3-2.
This standard specifies limits for emission and immunity and provides performance criteria for
signalling and telecommunications (S&T) apparatus which may interfere with other apparatus
in the railway environment, or increase the total emissions for the railway environment beyond
the limits defined in the appropriate standard and so risk causing Electro-Magnetic
Interference (EMI) to apparatus outside the railway system.
Apparatus which complies with the emission levels of IEC 61000-6-4 will meet the emission
requirements of this standard provided that emissions from any d.c. power port are within the
emissions limits specified for a.c. power ports. The immunity
