Introduction
This Technical Specification provides performance requirements and tests for low-voltage electrical
connectors deemed to be installed on board railway rolling stock, either indoors or outdoors. Safety
requirements and tests for electrical connectors are already covered in general by EN 61984. The additional
requirements and testing of specific characteristics demanded by rolling stock applications are set out in this
Technical Specification. One goal of this Technical Specification is to avoid retesting of electrical connectors
already in compliance with EN 61984 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 Technical Specification 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 B of this Technical Specification provide guidance.
Upon agreement between the parties involved, this Technical Specification may be used in conjunction with
existing connector detail specifications for interchangeability purposes.
Other standards may be developed in future under the umbrella format of this specification, for particular
connector designs for applications on board rolling stock, to fix dimensions for interchangeability and to set
the additional requirements for specific applications that, due to complexity and variety, are left here to
agreement between parties involved.
This Technical Specification does not cover
– connectors with breaking capacity (CBCs) as defined in EN 61984, 3.2, because on board rolling stock
connectors are not deemed to be operated (i.e. connected or disconnected) under load or when live,
either by means of procedures or by the presence of interlocks, as required by EN 50153,
NOTE For the purpose of this Technical Specification connectors on board rolling stock are therefore considered as being always
without breaking capacity, therefore where needed for safety reasons, adequate procedures or interlocks (i.e. locking devices that
cannot be opened without the aid of a special tool) shall be provided in the end application;
– non-rewirable connectors as defined in EN 61984, 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 Technical
Specification are therefore covered by the agreed choice of suitable mechanical and environmental
characteristics as suggested by Annex B.

1 Scope
This Technical Specification retains EN 61984 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 V per contact and frequencies below
3 MHz used for indoor and outdoor applications in railway rolling stock.
This Technical Specification identifies the application levels for electrical connectors based on:
– the severity of the service conditions in different rolling stock technologies;
– the intended use of the rolling stock;
– the location of the connector in the rolling stock system.
This Technical Specification is not applicable to internal connections of electronic devices such as
connectors for printed boards and rack-and-panel connectors.
