This European Standard was approved by CENELEC on 2010-05-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

Foreword
This European Standard was prepared by SC 9XB, Electromechanical material on board rolling stock, of
Technical Committee CENELEC TC 9X, Electrical and electronic applications for railways. It was
submitted to the CENELEC formal vote and was approved by CENELEC as EN 50206-2 on 2010-05-01.
This document supersedes EN 50206-2:1999.
The main changes brought by this revision are:
– simplification and standardisation of the tolerances for static contact force (Annexes A and B);
– adjustment of terms to TSI (static contact force instead of static force);
– deletion of Clause 10;
– update of normative references.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent rights.
The following dates were fixed:
– latest date by which the EN has to be implemented

at national level by publication of an identical

national standard or by endorsement
(dop) 2011-05-01
– latest date by which the national standards conflicting

with the EN have to be withdrawn
(dow) 2013-05-01

Introduction
The electrical power supply of a tractive unit is achieved by the collection of current from the contact wire
by means of one or more pantograph(s), installed on the traction unit or on the vehicle.
The contact strip of the pantograph which slides along the contact wire facilitates the transmission of
power.
The pantograph and the overhead line equipment form two oscillating sub-systems which can be
displaced. There exists a unilateral sliding linkage between them, which shall ensure continuous contact.
Their design shall allow for minimum wear of both sub-systems when used.

1 Scope
This European Standard defines the general assembly characteristics which are to be applied to
pantographs, to enable current collection from the overhead line equipment. It also defines the tests the
pantographs have to perform, excluding insulators.
This European Standard does not apply to pantograph dielectric tests, which are to be performed on the
pantograph installed on the vehicle roof. If no other requirement is agreed between customer and supplier,
insulation coordination according to EN 50124-1 may be used.
This European Standard does not apply to pantographs used on main line vehicles: these pantographs
are considered in EN 50206-1.
This European Standard relates to conventional suspended overhead line equipment and accessories.
The systems (or part of them) which are rigidly suspended will require special consideration between the
customer and the supplier.
