To date, UIC regulations specified that for a wheel to be used in Europe: - its design had to be standardized; - it had to conform to the quality requirements of UIC leaflet 812-3. In order to be able to adapt to new railway working conditions, on the one hand, and to facilitate the introduction of new technical solutions, on the other, it has been necessary to replace the concept of standardization with the definition of specifications. A wheel design shall meet these specifications to be accepted on the European network. This standard describes these specifications and states how to assess the wheel design. To be able to apply these specifications, it is essential to define the use of the wheel. This standard states how to define this use. At least four aspects are described with different purposes: - 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; - an acoustical aspect: to ensure that the solution chosen is as good as the reference wheel, for the use in question. For each of these three latter aspects, the rules proposed tend to limit the procedure, the easier the objectives are to attain by the wheel under study. This standard does not cover assessment of the hub nor of the static mechanical dimensioning of the wheel. Furthermore, this standard contains Amendment A2 which serves for adaptation of the new Directive 2008/57/EC on interoperability to the body of standards.
