Bibliography
This European Standard applies to torsion bars made of steel for anti-roll bar systems used on railway vehicles.This European Standard includes straight and bended torsion bars, but does not detail the other components of the anti-roll bar systems such as levers, bearings, bushes etc.This European Standard constitutes guidelines on the following topics:-design;-specification of technical requirements;-production requirements;-tests;-supply conditions.
