PD CEN/TR 15874:2009 Railway applications. Noise emission. Road test of standard for rail roughness measurement EN 15610:2009 PD CEN/TR 15874:2009 provides a road test to check that BS EN 15610:2009 can be interpreted consistently and leads to a consistent estimate of roughness spectrum when used by different measurers with different instruments.
