This document specifies a design assessment procedure of a forged and rolled monobloc wheel (RST). This assessment is carried out before the wheel is commissioned. This document describes, in particular, the assessment to be performed in order to use wheels on a European network which, in addition, have quality requirements in conformity with those defined in EN 13262.
This assessment requires that the conditions of use for the wheel are defined and this standard provides a method for defining those conditions.
The assessment of the design covers four aspects:
- a geometrical aspect: to allow interchangeability of different solutions for the same application;
­- a thermomechanical aspect: to manage wheel deformations and to ensure that braking will not cause wheels to fracture;
- a mechanical aspect: to ensure that no fatigue cracks occur in the wheel web and that no permanent deformation occurs under exceptional loading;
- an acoustic aspect: to ensure that the solution chosen is as good as the reference wheel.
This document does not cover assessment of the hub or of the rim.
This document has been drawn up for wheels of non­powered tread­braked wheelsets and applies in full to this type of wheel. For wheels on which disc brakes are mounted or toothed transmission wheels or even wheels with noise reduction devices, the requirements may be amended or supplemented.
For urban railway vehicles, other standards or documents may be used.

This European Standard:
— defines the forces and moments to be taken into account with reference to masses, traction and braking conditions;
— gives the stress calculation method for axles with outside axle journals;
— specifies the maximum permissible stresses to be assumed in calculations for steel grade EA1N, EA1T and EA4T defined in EN 13261:2020;
— describes the method for determination of the maximum permissible stresses for other steel grades;
— determines the diameters for the various sections of the axle and recommends the preferred shapes and transitions to ensure adequate service performance.
This European Standard is applicable for:
— axles defined in EN 13261:2020
— powered and non-powered axles and
— all track gauges3.
The powered axle design method of this European Standard applies to:
— solid and hollow powered axles for railway rolling stock;
— solid and hollow non-powered axles of motor bogies;
— solid and hollow non-powered axles of locomotives.
The non-powered axle design method of this standard applies to solid and hollow axles of railway rolling stock used for the transportation of passengers and freight that are not considered in the list above.
This European Standard is applicable to axles fitted to rolling stock intended to run under normal European conditions. Before using this European Standard, if there is any doubt as to whether the railway operating conditions are normal, it is necessary to determine whether an additional design factor has to be applied to the maximum permissible stresses. The calculation of wheelset axles for special applications (e.g. tamping/lining/levelling machines) may be made according to this European Standard only for the load cases of free-rolling and rolling in train formation. This European Standard does not apply to the loads induced by the vehicles in their working mode. They are calculated separately.
This method can be used for light rail and tramway applications.

Four steel grades, ER6, ER7, ER8 and ER9 are defined in this standard; for European freight wagon interoperability purposes only grades ER6, ER7 and ER8 are applicable.
NOTE 1   Grade ER6 is not normally fit for the duty of application to freight wagons; it is normally applied in low axleload situations.
Certain characteristics are defined according to a category 1 or a category 2. Category 1 is generally chosen when the train speed is higher than 200 km/h. Freight vehicles running at speeds lower than 200 km/h generally use wheels of Category 2.
These categories can sometimes be subdivided, depending upon the characteristics.
This standard is applicable to solid forged and rolled wheels which are made from vacuum degassed steel and have a chilled rim. They are to have already been used in commercial conditions on a European network in a significant quantity, or to have satisfied a technical approval procedure according to EN 13979-1 for their design.
NOTE 2  The definition of other wheels may be found in other documents, such as UIC leaflets or ISO standards.
NOTE 3   The technical approval procedure is not within the scope of this standard.

The aim of this document is to define a design assessment procedure of a forged and rolled monobloc wheel (RST). This assessment is carried out before the wheel is commissioned. This document describes, in particular, the assessment to be performed in order to use wheels on a European network which, in addition, have quality requirements in conformity with those defined in EN 13262.
This assessment requires that the conditions of use for the wheel are defined and this standard provides a method for defining those conditions.
The assessment of the design covers four aspects:
- a geometrical aspect: to allow interchangeability of different solutions for the same application;
- a thermomechanical aspect: to manage wheel deformations and to ensure that braking will not cause wheels to fracture;
- a mechanical aspect: to ensure that no fatigue cracks occur in the wheel web and that no permanent deformation occurs under exceptional loading;
- an acoustic aspect: to ensure that the solution chosen is as good as the reference wheel.
This document does not cover assessment of the hub or of the rim.
This document has been drawn up for wheels of non-powered tread-braked wheelsets and applies in full to this type of wheel. For wheels on which disc brakes are mounted or toothed transmission wheels or even wheels with noise reduction devices, the requirements may be amended or supplemented.
For urban railway vehicles, other standards or documents may be used.

This European Standard specifies the characteristics of railway wheels for use on European networks. !Four steel grades, ER6, ER7, ER8 and ER9 are defined in this standard; for European freight wagon interoperability purposes only grades ER6, ER7 and ER8 are applicable. NOTE 1 Grade ER6 is not normally fit for the duty of application to freight wagons; it is normally applied in low axleload situations." !Certain characteristics are defined according to a category 1 or a category 2. Category 1 is generally chosen when the train speed is higher than 200 km/h. Freight vehicles running at speeds lower than 200 km/h generally use wheels of Category 2." These categories can sometimes be subdivided, depending upon the characteristics. This standard is applicable to solid forged and rolled wheels which are made from vacuum degassed steel and have a chilled rim. They are to have already been used in commercial conditions on a European network in a significant quantity, or to have satisfied a technical approval procedure according to EN 13979-1 for their design. !NOTE 2" The definition of other wheels may be found in other documents, such as UIC leaflets or ISO standards. !NOTE 3" The technical approval procedure is not within the scope of this standard. !NOTE 4" Rim-chilled" describes heat treatment of the rim, the aim of which is to harden the rim and to create compressive residual stresses in the rim.

This European Standard specifies the characteristics of axles for use on European networks.
It defines characteristics of forged or rolled solid and hollow axles, made from vacuum-degassed steel grade
EA1N1 that is the most commonly used grade on European networks. For hollow axles, this standard applies
only to those that are manufactured by machining of a hole in a forged or rolled solid axle
In addition, the particular characteristics for axles in grade EA1T1 and EA4T1 are given in Annex A.
Two categories of axle are defined, category 1 and category 2. Generally, category 1 is chosen when the
operational speed is higher than 200 km/h.
This standard is applicable to axles that are designed in accordance with the requirements of EN 13103 and
EN 13104.
NOTE Different values for some characteristics may be agreed if a particular process of fabrication (e.g. cold rolling,
shot peening, shot peening, steel cleanliness, reduction ratio, improved material properties from melting and heat
treatment processes, etc.) has an influence on them.
