Three grades of steel and five rail profiles are specified. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition
28、 cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、rms and definitions apply. 3.1 check rail rail laid close to the gauge face of a running rail which does not carry a railway wheel but ensures, by guidance of the wheel, the safe passage of both wheels of the axle through small radius curves, switches, crossings by not allowing the flange of either
30、wheel to ride up over the running surface of the running rails 3.2 guard rail non-running rail mounted either inside or outside the running rail to protect vehicle, bridge, viaduct and other structures in the event of a derailment 3.3 acceptance tests tests carried out as part of the process and pro
31、duct control system, normally on a heat, sequence or tonnage basis 3.4 running rail profile that is designed to carry a railway wheel 4 Information to be supplied by the purchaser The purchaser shall supply the supplier with the following information when inviting tenders to supply: a) rail profiles
32、 (see Annex A); b) steel grades (see Table 1); c) lengths of rail. 5 Steel grades The applicable steel grades are given in Table 1.

Rail transition points are also given in Annex A, Figures A.6 to A.10. 7 Manufacture 7.1 Product integ
36、rity Rails shall be produced under a comprehensive system of factory production control, which shall ensure confidence in the conformity of the finished product. The system shall address this European Standard to ensure that the finished products consistently comply with requirements to achieve the
37、product integrity necessary to provide assurance of product safety in track. Manufacturers shall demonstrate continuing compliance, including documented evidence, with the factory production control system required. Manufacturers having a factory production control system, which complies with EN ISO
38、 9001, shall be recognised as satisfying the minimum requirements specified by this clause. 7.2 Identification The rail shall carry an identification to show the manufacturer the number of the heat, the grade of steel and the rail profile. Cold stamping is not allowed. 8 Acceptance tests 8.1 Chemica
39、l composition Chemical composition limits for these steel grades are given in Table 1.

40、n in the steel using an on-line immersion probe system. At least two liquid samples shall be taken from the first heat of any sequence using a new tundish and one from each of the remaining heats and analysed for hydrogen content. The first sample from the first heat in a sequence shall be taken fro
41、m the tundish at the time of the maximum hydrogen concentration. The heats shall be assessed according to hydrogen content in accordance with Table 2. The blooms from group 1 heats shall be deemed to be satisfactory. The blooms from group 2 heats shall be slowly cooled or isothermally treated and al
42、l heats shall be tested in the rail form. Table 2 Hydrogen content of heats Hydrogen content 10-4% (ppm) Heats Steel grade R200 All other steel grades Group 1 3,5 2,5 Group 2 3,5 2,5 If the hydrogen contents of the first samples of a first heat or the heat sample of a second or further heat do not c
43、omply with the requirements of Table 1 then the blooms made before those samples are taken shall be slowly cooled or isothermally treated. Also all blooms made before the hydrogen content eventually complies with the requirements in Table 1 shall be slowly cooled or isothermally treated. When testin
44、g of rails is required rail samples shall be taken at the hot saw at a frequency of one per heat at random. However on the first heat in a sequence, the rail sample shall be from the last part of a first bloom teemed on any strand. Hydrogen determination shall be carried out on samples taken from th
45、e centre of the rail head. If any test result fails to meet the requirements stated in Table 1 the heat shall be rejected. 8.3 Hardness Brinell hardness tests shall be carried out on the contact surface in accordance with EN ISO 6506-1, at a frequency of one test per heat. The surface is prepared by
46、 grinding off 0,5 mm approximately prior to testing. The hardness values shall meet the requirements shown in Table 1. NOTE Tensile properties are not required by this European Standard. However, they are generally similar to those of the comparable grades of EN 13674-1. 8.4 Profile tolerances The n
47、ominal dimensions of the check rail profile and the actual dimensions anywhere on the rail shall not differ by more than the tolerances given on the profile drawings in Annex A, Figures A.1 to A.5. Check rail transition points are also given in Annex A, Figures A.6 to A.10. Licensed Copy: Wang Bin,

If the rail shows evidence of twist on an inspection bed, it will be checked by inserting feeler gauges b
49、etween the base of the check rail and the rail skid nearest the rail end. If the gap exceeds 5 mm the rail shall be rejected. 8.6 Cutting The tolerance on length shall be plus or minus 10 mm. 8.7 Surface quality The maximum permissible depth of imperfection shall be 1 mm. Protrusions on the contact face shall be dressed to shape by grinding.
