This European Standard specifies the technical requirements and the measurements to be made for the acceptance of work to reprofile longitudinally and/or transversely the heads of railway rails. For acceptance purposes, two classes of longitudinal profile and three classes of transverse profile tolerance are defined. Annexes describe procedures to verify reference instruments to be used for these measurements as well as methods to approve non-reference instruments to be used for measurements. This European Standard applies to reprofiled vignole railway rails 46 kg/m and above. It does not apply for acoustic rail reprofiling. A form of acceptance documentation that may be used is given in Annex E.
