EVS-EN 14531-1:2015

This European Standard describes general algorithms which may be used for all types of train sets, units or single vehicles, including high speed, locomotive and passenger coaches, conventional vehicles and wagons. This standard does not specify the performance requirements. It enables the estimation and,/or comparison by calculation of the various aspects of the performance: stopping or slowing distances, dissipated energy, power, force calculations and immobilization braking. If it is required to validate, verify or assess braking performance it is recommended that a more detailed calculation is performed in accordance with prEN 14531-2, i. e. a step by step calculation. This European Standard contains generic examples of the calculation of brake forces for individual brake equipment types and calculation of stopping distance and immobilisation braking relevant to a train (see Annex C and D).
