This European Standard specifies Vignole railway rails of 46 kg/m and greater linear mass, for general and high speed railway track usage. Seven pearlitic steel grades are specified covering a hardness range of 200 HBW to 390 HBW and include non heat treated carbon manganese steels, non heat treated alloy steels, and heat treated carbon manganese steels. There are 21 rail profiles specified in this Standard. Two classes of rail straightness are specified, differing in requirements for straightness, surface flatness and crown profile. Two classes of profile tolerances are specified.
