Defines the characteristics of, and technical Approval requirements for, cast railway wheels for conventional rail operation.

This British Standard specifies the characteristics of, and technical approval requirements for, cast railway wheels for conventional rail operation. It can be applied in conjunction with BS or BS EN standards for axles and wheelsets. This standard is not applicable to urban rail. Three steel grades, C48, C56 and C64, are defined in this standard. NOTE1 For the purpose of this British Standard, the steels referred to as C48, C56 and C64 are based on those defined as AAR Class L, A and B respectively. This British Standard is applicable to cast wheels which are rim-chilled and have their wheel webs shot peened. NOTE2 \'Rim-chilled\' is a heat treatment of the rim, the aim of which is to harden the rim and to create compressive residual stresses in the rim. NOTE3 Cast wheels are shot peened to improve the web fatigue strength. The wheels defined in this British Standard are for applications up to 120km/h (i.e. 75mph). It only applies to wheels of new design or new application. These requirements are intended to be used to assess the validity of the design choice for the proposed use and constitute the technical approval procedure. This British Standard does not cover assessment of the hub nor of the static mechanical dimensioning of the wheel.
