This European Standard specifies a direct method for characterizing the surface roughness of the rail andwheel associated with rolling noise ("acoustic roughness"), in the form of a one-third octave band spectrum. Thisstandard describes a method for:a) selecting measuring positions along a track or selecting wheels of a vehicle;b) selecting lateral positions for measurements;c) the data acquisition procedure;d) measurement data processing in order to estimate a set of one-third octave band roughness spectra;e) presentation of this estimate for comparison with limits of acoustic roughness;f) comparison with a given upper limit in terms of a one-third octave band wavelength spectrum;g) the measuring system requirements.It is applicable to:a) the performance testing of reference track sections in relation to the acceptance test for noise emitted byrailway vehicles;b) the performance testing of track sections in relation to noise emitted by railway vehicles;c) the acceptance of the running surface condition only in the case where the acoustic roughness is theacceptance criterion;d) the assessment of the wheel surface condition as an input for the acoustic acceptance of brake blocks;e) the assessment of the wheel and rail roughness as input to the calculation of combined wheel railroughness;f) the diagnosis of wheel-rail noise issues for specific tracks or wheels;g) the assessment of the wheel and rail roughness as input to rolling noise modelling;h) the assessment of the wheel and rail roughness as input to noise source separation methods.It is not applicable to the:a) measurement of roughness using an indirect method;b) direct measurement of combined wheel-rail roughness;c) analysis of the effect of wheel-rail interaction, such as a "contact filter";d) approval of rail and wheel reprofiling, including rail grinding operations, except for those where theacoustic roughness is specifically the approval criterion (and not the grinding quality criteria as providedin e. g. EN 13231);e) characterisation of track and wheel geometry except where associated with noise generation.
