DIN 45673-5:2010-08

This standard series has been developed as characteristic values had to be determined in the laboratory to describe the static and dynamic properties of resilient elements used in railway tracks, taking into account the final assembly position, and to indicate them in the product description. This shall facilitate comparisons between various products and allow for calculation of the vibration reducing effect. It applies to all kinds of rail vehicle (tramways, underground trains, suburban trains, standard gauge railways). Furthermore, information is given on fitness for purpose tests of resilient elements and pointers on quality control within the framework of quality assurance are provided. However, requirements for the properties of systems with resilient elements are not included in this standard series. The recently published standards are revisions; the 2000 edition of DIN 45673-1 has been divided into several parts. DIN 45673-5 specifies laboratory test procedures for the determination of characteristic values which describe the static and dynamic properties of under-ballast mats (UBM). This standard series has been prepared by Working Committee NA 001-03-15 AA (NALS/VDI C 15) "Schwingungsminderung in der Umgebung von Verkehrswegen" ("Reduction of vibration in the vicinity of traffic routes").
