DIN CEN/TR 15874:2016-09

The vibrations generated by the rolling of the wheel on the rail lead to sound radiation at the wheel, rail and sleeper. The combined roughness of the wheel and rail running surfaces, which excite the structures to vibrate due to the acting contact forces, is largely responsible for this. DIN EN 15610:2009 provides a method to determine the rail running surface roughness in the acoustically relevant range of wavelengths. Before DIN EN 15610:2009 was published, a field test was carried out to determine the extent to which the draft standard was interpreted uniformly by different measurement teams and whether the application of the standard with different measuring instruments resulted in a comparable estimate of the roughness spectrum. DIN CEN/TR 15874 (DIN SPEC 45659) describes the field test for the determination of the acoustic roughness of railroad running surfaces in application of DIN EN 15610:2009. The European technical report on which it is based has been prepared in Working Group WG 3 "Acoustics" of CEN/TC 256 "Railway applications". The German committee responsible for this standard is NA 001-01-05-01 UA "Spurgebundene Fahrzeuge - Kenngrößen" ("Rail vehicles - Characteristics") at DIN/VDI Standards Committee Acoustics, Noise Control and Vibration Engineering (NALS).
