European foreword

This document (EN 15313:2024) 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of an identical text or by endorsement, at the latest by April 2025, and conflicting national standards shall be withdrawn at the latest by April 2025.

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 15313:2016.

In comparison with the previous edition, the following technical modifications have been made:

a clearer definition of the signs to identify thermal overload of wheels and associated pictures;
the maintenance requirements to be followed when thermal overloading of a wheel is identified.

This document has been prepared under a standardization request addressed to CEN by the European Commission. The Standing Committee of the EFTA States subsequently approves these requests for its Member States.

Introduction

The objectives of this amendment to EN 15313:2016 are to:

incorporate the appropriate results of the ERA Joint Network Secretariat “broken wheels” and Joint Sector Group task force.

1 Scope

To ensure safety and interoperability, this document gives:

the limits for in-service and off-vehicle wheelsets;
the operations to be carried out for which the specific values (and/or criteria) remain to be defined in the maintenance plan.

This document applies to wheelsets and axleboxes complying with the following European standards:

EN 13103‑1:2017+A1:2022;
EN 13260:2020, EN 13261:2020, EN 13262:2020;
EN 13979‑1:2023;
EN 13715:2020;
EN 13749:2021+A1:2023;

that comprise:

the axle fitted with wheels of diameters greater than or equal to 330 mm;
axleboxes with bearings and grease.

This document is also applicable to wheelsets:

fitted with brake discs, final drive, transmission or noise-damping systems, as appropriate;
not complying with the above European standards, but complying with the international requirements in force, for example in UIC leaflets, before the approval of these standards;
with tyred wheels;
with resilient wheels.

For equipment not covered by Directive (EU) 2016/797, this European Standard can be applied, noting that different values can be used.

All dimensions in this document are in millimetres (mm).

It is necessary to describe in a specific document the tasks to be performed in order to maintain wheelsets within the limits defined therein.

NOTE The specific values and criteria are defined in an appropriate maintenance plan.
