Bibliography

The aim of this European Standard is to define the requirements that a monobloc wheel of a freight of passenger railway vehicle non-powered axle shall meet in order to be able to be used on a European network. For wheels of powered axles or wheels with noise dampers, the requirements may be amended or supplemented. For light vehicles and tramways, other standards or documents accepted by the customer and supplier may be used. This European Standard only applies to wheels of new design. These requirements are intended to assess the validity of the design choice for the proposed use. The assessment of these requirements is the technical approval procedure. This European Standard is applicable to forged and rolled wheels for which the quality requirements are defined in !EN 13262".
