Beskrivelse

This European Standard specifies laboratory test procedures to determine the dynamic stiffness of resilient components of track for the purpose of evaluating the environmental noise and vibration performance of the track.

This standard is applicable to complete track fastening assemblies and to pad components of fastening systems.

It is applicable to specimens of a single rail seat fastener.

It is applicable to the measurement of a tangent, dynamic stiffness under a prescribed pre-load and the associated hysteretic damping loss factor.

It provides measurement methods and pre-load, excitation and frequency range conditions for application to ground borne and structure borne noise as well as for rolling noise.

It provides measurement methods and pre-load, excitation and frequency range conditions for application to ground borne and structure borne noise as well as for rolling noise.

It is not applicable to the measurement of the stiffness of pads and fastening assemblies under static or low frequency dynamic loading which is specified in EN 13146-9.
