This European Standard shall be given the status of a n

20、ational standard, either by publication of an identical text or by endorsement, at the latest by July 2012, and conflicting national standards shall be withdrawn at the latest by July 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

21、rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 13231-3:2006. The changes with respect to the previous document (EN 13231-3:2006) include: a) a reduced number of acceptance criteria for the longitudinal profile (only

22、 one instead of three) in line with current European practice; b) reference points for interpretation of transverse profiles corresponding with the gauge recording points; c) simplified methods to prove measurement systems (for reference and approved instruments as described in Annexes A and B); d)

23、introduction of a procedure to routinely demonstrate acceptability of approached instruments in Annex D; e) integration of normative Annexes A, B, C and D. This European Standard is one of the series EN 13231 “Railway applications Track Acceptance of works“ as listed below: Part 1: Works on ballaste

BS EN 13231-3:2012EN 13231-3:2012 (E) 5 1 Scope 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

27、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 us

28、ed 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. 2 Normative references The following referenced documents are indispens
