European foreword
This document (EN 13715:2020) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2021, and conflicting national standards shall
be withdrawn at the latest by January 2021.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 13715:2006+A1:2010.
This new revision includes minor amendments, mainly editorial, to help to fulfil TSI requirements.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive 2016/797/EU.
For relationship with EU Directive 2016/797/EU, see informative Annex ZA, which is an integral part of
this document.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,

Introduction
This document states requirements that are in accordance with the principles adopted by the
International Union of Railways.
It describes the rules, parameters and construction methods of the wheel tread profile.
It defines the geometry of the flange and reverse slope. The thicknesses and height of the flange are
determined by the railway undertaking or its representative in compliance with the normative
documents in force.
It defines the coordinates and geometry of the following three reference tread profiles of the wheels
and their reverse slope:
th
— 1/40 (reverse slope 15 %);
— S1002 (reverse slope 6,7 %, other value used 15 %) in conformity with UIC Leaflet 510-2;
— EPS (reverse slope 10 %) equivalent to profile P8 of the United Kingdom with a flange 30 mm thick.
These three reference profiles are defined in Annexes B, C and D and represent original profiles from
the time of their design, the flanges having been harmonized to a 32,5 mm flange thickness.
It defines the tolerances needed to achieve calibration control.
All the dimensions in this document are given in millimetres.
1 Scope
This document defines the tread profiles of wheels with a diameter equal or greater than 330 mm used
on rolling stock submitted to the Directive 2016/797/EU. These profiles apply to new wheels, whether
free-standing or assembled as wheelsets, as well as to wheels that require reprofiling during
maintenance.

document describing the requirements pertaining to specific parameters in addition to the
requirements of this document
4 General
Given that this document describes three reference profiles used in Europe, any other profile that does
not conform to this document shall be defined in a technical specification.
NOTE The profile is defined in the technical specification, usually agreed on between the railway undertaking
and the infrastructure manager.
5 Definition of the tread profile
The tread profile is shown in Figure 1.
