This European Standard specifies the laboratory test procedure to determine: a) the maximum longitudinal force that can be applied to a rail@ secured to a sleeper@ bearer or element of slab track by a rail fastening assembly@ without non-elastic displacement of the rail occurring@ or the longitudinal stiffness at a specified longitudinal displacement of a specimen of embedded rail with an adhesive fastening system@ and@ for any type of fastening@ b) the shear displacement and slip data required for track-bridge interaction calculations
