1 Scope
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, as well as requirements for wheel rotation monitoring (WRM)..
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.
