Scope

This document specifies laboratory test procedures to determine a high-frequency dynamic stiffness, “acoustic stiffness”, of resilient components of rail fastening assemblies.
This document is applicable to complete rail fastening assemblies and to pad components of fastening systems including both discrete and continuous fastening systems.
It is applicable to the measurement of the dynamic transfer 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 is not applicable to the measurement of the stiffness of pads and fastening assemblies under static or low-frequency dynamic loading used for track mechanics.
