Railway applications - Wheelsets and bogies - Wheels - Product requirements
This document specifies the characteristics of wheels for all heavy rail track gauges.
This document applies to heavy rail vehicles and applies, in principle, to other vehicles such as urban rail vehicles. Five steel grades, ER6, ER7, ER8, ERS8 and ER9, are defined in this document.
NOTE 1 Steel grade ERS8 has been introduced in this document as an optimization of steel grades ER8 and ER9 due to contact fatigue (RCF), taking into account service feedback from Europe, for example, BS 5892-3 in force in the United Kingdom.
Some features are provided as a Category 1 or Category 2 function.
The requirements defined in this document apply to cylindrical bores. Most requirements also apply to wheels with tapered bores. Specific requirements for tapered bores (e.g. geometrical dimensions, etc.) are defined in the technical specification.
This document applies to monobloc wheels in vacuum degassed steel, forged and rolled, with surface treated rims, which have already been the subject of extensive commercial applications on a European network or have complied with a technical approval procedure according to EN 13979-1:2020 to validate their design.
Annex A describes the evaluation process for accepting new materials that are not included in this document.
This document defines the requirements to be met for wheels; the technical approval procedure is not part of the scope of this document.
NOTE 2 A "surface-treated rim" is achieved by heat treatment which aims to harden the rim and create compressive residual stress.

Das vorliegende Dokument legt die Eigenschaften von Eisenbahnrädern für alle Spurweiten fest.
Dieses Dokument ist für Vollbahnfahrzeuge und grundsätzlich für andere Fahrzeuge wie Nahverkehrsfahrzeuge anwendbar. Im vorliegenden Dokument werden fünf Stahlgüten, ER6, ER7, ER8, ERS8 und ER9, definiert.
ANMERKUNG 1 Die Stahlgüte ERS8 wurde im vorliegenden Dokument als eine optimierte Variante der Stahlgüten ER8 und ER9 in Hinsicht der Kontaktermüdung (RCF) und unter Berücksichtigung von Erfahrungswerten aus dem europäischen Bahnbetrieb, z. B. aus der in Großbritannien geltenden Norm BS 5892 3, eingeführt.
Bestimmte Eigenschaften werden nach Kategorie 1 oder Kategorie 2 angegeben.
Die in dem vorliegenden Dokument festgelegten Anforderungen sind für zylindrische Bohrungen anzuwenden. Die meisten Vorschriften sind auch für Räder mit kegelförmigen Bohrungen anzuwenden. Spezielle Anforderungen an kegelförmige Bohrungen (z. B. geometrische Abmessungen usw.) sind in der technischen Spezifikation festgelegt.
Dieses Dokument gilt für geschmiedete und gewalzte Vollräder, die aus vakuumentgastem Stahl hergestellt werden und eine Radkranzvergütung erhalten haben. Sie müssen bereits in einer bedeutenden Anzahl und unter kommerziellen Bedingungen in einem europäischen Eisenbahnnetz eingesetzt sein oder die Konstruktion muss eine Zulassungsprüfung nach EN 13979 1:2020 bestanden haben.
Anhang A beschreibt das Bewertungsverfahren für die Zulassung neuer Werkstoffe, die im vorliegenden Dokument nicht behandelt werden.
Das vorliegende Dokument legt die Produkt-Anforderungen fest, die für Räder erfüllt werden müssen; das technische Zulassungsverfahren ist nicht Bestandteil des Anwendungsbereichs des vorliegenden Dokuments.
ANMERKUNG 2 Eine Radkranzvergütung wird durch Wärmebehandlung erreicht, deren Ziel die Härtung des Radkranzes und die Schaffung von Druckeigenspannungen ist.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 256.
If this draft becomes a European Standard, CEN 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.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.
Warning : This document is not a European Standard. It is distributed for review and comments. It is subject to change without
notice and shall not be referred to as a European Standard.
