Over deze norm
The aim of this European Standard is to define a method for the design assessment of a forged and rolled monobloc wheel of freight or passenger RST. This assessment is made before entry into service. This standard describes, in particular, the assessment to be performed in order to use wheels on a European network which, moreover, have quality requirements in conformity with those defined in EN 13262. This assessment requires that the conditions of use of the wheel are defined and this standard provides a method for the definition of those conditions. The design assessment has four different 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 break; - a mechanical aspect: to ensure that no fatigue cracks occur in the 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, for the use in question. This standard does not cover assessment of the hub and the rim. 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 may be used.
