This standard: 1) defines the forces and moments to be taken into account with reference to masses and braking conditions; 2) gives the stress calculation method for axles with outside axle journals; 3) specifies the maximum permissible stresses to be assumed in calculations for steel grade EA1N defined in EN 13261; 4) describes the method for determination of the maximum permissible stresses for other steel grades; 5) determines the diameters for the various sections of the axle and recommends the preferred shapes and transitions to ensure adequate service performance.This standard is applicable to: 6) solid and hollow axles of railway rolling stock used for the transportation of passengers and freight; 7) axles defined in EN 13261; 8) all gauges3.This standard is applicable to axles fitted to rolling stock intended to run under normal European conditions. Before usingThis 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 wheelsets for special applications (e. g. tamping/lining/levelling machines) may be made according toThis standard only for the load cases of free-running and running in train formation.This standard does not apply to workload cases. They are calculated separately. For light rail and tramway applications; other standards or documents agreed between the customer and supplier may be applied. Non-powered axles of motor bogies and locomotives are analysed according to the requirements of EN 13104.
