![]() ![]() The base profile is that obtained with a flange 32,5 mm thick and 28 mm high. situated 70 mm from the internal face of the wheel. The Z-axis is perpendicular to the latter with the positive values towards the outside of the wheel. The V-axis is parallel to the axis of rotation of the wheel with the positive values towards the external face of the wheel. The reverse slope shall be in the range 6.7 % to 15 %. a zone 81 (either Bia or Bib) - Al - I, comprising the reverse slope and chamfer, unique to each reference profile. The coordinates are given in Annexes B, C and 0 for the three reference profiles including point DO a zone Ci - Bi (either Bia, or Bib) unique to each reference profile. a connection zone Dl - Cl, unique to each reference profile, to make a tangential connection at point Ci two zones H2 - Sand S - Dl, with fixed geometry NOTE The profile is defined in the technical specification, usually agreed on between the railway undertaking and the infrastructure manager. Given that this document describes three reference profiles used in Europe, any other profile that does not conform to this document shall be defined in a technical specification.
