scope:

This European Standard describes a general algorithm that may be used in all types of high speed and conventional vehicle applications, including self-propelling thermal or electric trains, thermal or electric traction units; passenger carriages, mobile railway infrastructure construction and maintenance equipment and freight wagons. This standard does not specify the performance requirements. It enables the calculation of the various aspects of the performance: stopping or slowing distances, dissipated energy, force calculations and immobilization braking. This standard enables the verification by calculation of the stopping, slowing and immobilization performance requirements for high speed and conventional trains operating on high speed and conventional infrastructure. Other calculation methods may be used providing that the order of accuracy achieved is in accordance with this European Standard. This standard presents: a) example of distance and other dynamic calculations, see Annex C; b) example of immobilisation calculations, see Annex D.
