This standard specifies laboratory test procedures for determining the parameters used to describe the static and dynamic properties of discrete resilient rail fastening systems (rail fastening systems for single-support seats) used on all types of railways. The standard covers those parameters that are relevant for describing the effectiveness of a track structure in mitigating vibration, that is, in reducing the emission of vibration and structure-borne noise. In this standard the specifications of DIN EN 13146-9 in respect of the vibrationreducing effectiveness are given in more detail in some cases and are supplemented in others.
In addition to specifying the basic testing of relevant properties of resilient elements for rail fastenings and of rail fastening systems, this standard also specifies additional procedures for testing fitness for purpose and provides information on quality monitoring as part of quality assurance. However, this standard does not contain requirements pertaining to the properties of resilient and highly resilient rail fastening systems.
