BAS EN 15595+A1:2012

This European Standard specifies the minimum criteria for system acceptance/type approval of a new wheel slide protection system and implementation of accepted WSP to specific vehicle applications and route requirements. This includes the design, testing and quality assessment of the WSP system and its components. This European Standard is applicable to wheel slide protection systems for pneumatic braking systems without taking the type of vehicles and track-gauge into consideration. The general principles of this standard can also apply as a reference for other types of braking systems and other kinds of railway vehicles. The system is designed to control the sliding of wheels of railway vehicles during braking under degraded adhesion conditions to prevent wheel damage and to minimize the extension of the stopping distance under degraded adhesion conditions by optimizing the available adhesion between wheel and rail. This European Standard does not apply to the following categories of vehicles: 1) tramways; 2) light railways; 3) metros on steel wheels; 4) metros on rubber tyred wheels.
