Railway applications - Rolling stock - Electrical connectors - Requirements and test methods
This International Standard retains IEC 61984:2008 as the minimum performance requirements for railway rolling stock electrical connectors.
It identifies additional terms, test methods and performance requirements for single-pole and multipole connectors with rated voltages up to 1 000 V, rated currents up to 125 A per contact and frequencies below 3 MHz used for indoor and outdoor applications in railway rolling stock.
This International Standard does not cover:
- connectors with breaking capacity (CBCs) as defined in IEC 61984:2008, 3.2, because on board rolling stock connectors are not intended to be operated (i.e. mated and unmated) under load or when live, either by means of procedures or by the presence of interlocks, as required by IEC 61991;
- non-rewirable connectors as defined in IEC 61984:2008, 3.5;
- automatic couplers, due to their additional mechanical complexity and the need for more specific requirements and testing;
- inter-vehicle jumpers, as they are connector and cable assemblies whose characteristics depend on those of both elements. Inter-vehicle connectors within the limits set in the scope of this International Standard are therefore covered by the agreed choice of suitable mechanical and environmental characteristics as defined by Annex B, and suggested by Annex C.
This International Standard identifies the application levels for electrical connectors based on
a) the severity of the service conditions in different rolling stock technologies,
b) the intended use of the rolling stock,
c) the location of the connector in the rolling stock system.
This International Standard is not applicable to internal connections of electronic devices such as connectors for printed boards and rack-and-panel connectors.

L'IEC 62847:2016 reconnaît les exigences de l'IEC 61984:2008 comme étant les exigences de performances minimales des connecteurs électriques sur matériel roulant ferroviaire et identifie d'autres termes, méthodes d'essais et exigences de performances pour les connecteurs unipolaires et multipolaires avec des tensions assignées jusqu'à 1 000 V, des courants assignés jusqu'à 125 A par contact et des fréquences inférieures à 3 MHz, utilisés pour des applications intérieures et extérieures sur matériel roulant ferroviaire.
Železniške naprave - Vozna sredstva - Električni konektorji - Zahteve in preskusne metode
Ta mednarodni standard kot najnižjo zahtevo glede zmogljivosti električnih konektorjev železniških voznih sredstev ohranja standard IEC 61984:2008.
Opredeljuje dodatne pogoje, preskusne metode in zahteve glede zmogljivosti za enopolne in večpolne konektorje z nazivnimi napetostmi do 1000 V, nazivnimi toki do 125 A na stik in frekvencami pod 3 MHz, ki se uporabljajo za notranje in zunanje naprave pri železniških voznih sredstvih.
Ta mednarodni standard ne zajema:
– konektorjev z zmogljivostjo prekinitve (CBC), opredeljenih v točki 3.2 standarda IEC 61984:2008, ker konektorji na voznih sredstvih niso namenjeni za delovanje (tj. v spojenem in ločenem stanju) pod obremenitvijo ali napetostjo, bodisi s postopki ali prisotnostjo zapornih sistemov, kot to zahteva standard IEC 61991;
– konektorjev, ki jih ni mogoče znova povezati, kot je opredeljeno v točki 3.5 standarda IEC 61984:2008;
– samodejnih spojnikov zaradi njihove dodatne mehanske kompleksnosti ter podrobnejših zahtev in preskusov;
– povezovalnih elementov med vozili, tj. sklopov konektorjev in kablov, katerih lastnosti so odvisne od lastnosti obeh elementov. Konektorji za uporabo med vozili so v mejah, določenih v področju uporabe tega mednarodnega standarda, zajeti z dogovorjeno izbiro ustreznih mehanskih in okoljskih lastnosti, kot je opredeljeno v dodatku B in predlagano v dodatku C.
Ta mednarodni standard opredeljuje ravni uporabe za električne konektorje na podlagi
a) resnosti pogojev obratovanja pri različnih tehnologijah železniških voznih sredstev,
b) predvidene uporabe železniških voznih sredstev,
c) namestitve konektorja v sistemu železniških voznih sredstev.
Ta mednarodni standard se ne uporablja za notranje povezave elektronskih naprav, kot so konektorji za tiskana vezja ter konektorji za omare in panele.

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.

INTRODUCTION
This International Standard provides performance requirements and tests for low-voltage
electrical connectors intended to be installed on board rolling stock, either inside or outside.
Safety requirements and tests for electrical connectors are already covered in general by
IEC 61984:2008. The additional requirements and testing of specific characteristics
demanded by rolling stock applications are set out in this International Standard. One goal of
this International Standard is to avoid retesting of electrical connectors already in compliance
with IEC 61984:2008 for those characteristics that have been assessed suitable also for use
on board rolling stock.
Among the additional requirements for use on board rolling stock, those that can be verified
by documentation of tests on the raw materials are distinguished from those to be assessed
by tests on the component.
Due to the wide spectrum of existing and future specific rolling stock applications of electrical
connectors, this International Standard does not select any particular geometric configuration
of connectors, nor establish any particular values for electrical ratings such as voltage and
current, or for any other characteristic. All such details should be selected and agreed
between the parties involved (e.g. manufacturer and user) depending on the electrical,
mechanical and environmental conditions expected in the intended use. Annexes A and C of
this International Standard provide guidance.
Upon agreement between the parties involved, this International Standard may be used in
conjunction with existing connector detail specifications for interchangeability purposes.
Specific standards based on this generic International Standard may be developed in the
future to address particular connector requirements and designs, for instance, to fix
dimensions for interchangeability and to set additional requirements for specific applications
that, due to complexity and variety, are left here to agreement between parties involved.

RAILWAY APPLICATIONS – ROLLING STOCK – ELECTRICAL
CONNECTORS – REQUIREMENTS AND TEST METHODS
1 Scope
This International Standard retains IEC 61984:2008 as the minimum performance
requirements for railway rolling stock electrical connectors.
It identifies additional terms, test methods and performance requirements for single-pole and
multipole connectors with rated voltages up to 1 000 V, rated currents up to 125 A per contact
and frequencies below 3 MHz used for indoor and outdoor applications in railway rolling stock.
This International Standard does not cover:
• connectors with breaking capacity (CBCs) as defined in IEC 61984:2008, 3.2, because on
board rolling stock connectors are not intended to be operated (i.e. mated and unmated)
under load or when live, either by means of procedures or by the presence of interlocks,
as required by IEC 61991;
• non-rewirable connectors as defined in IEC 61984:2008, 3.5;
• automatic couplers, due to their additional mechanical complexity and the need for more
specific requirements and testing;
• inter-vehicle jumpers, as they are connector and cable assemblies whose characteristics
depend on those of both elements. Inter-vehicle connectors within the limits set in the
scope of this International Standard are therefore covered by the agreed choice of suitable
mechanical and environmental characteristics as defined by Annex B, and suggested by
Annex C.
This International Standard identifies the application levels for electrical connectors based on
a) the severity of the service conditions in different rolling stock technologies,
b) the intended use of the rolling stock,
c) the location of the connector in the rolling stock system.
This International Standard is not applicable to internal connections of electronic devices such
as connectors for printed boards and rack-and-panel connectors.
