27、nd definitions For the purposes of this document, the following terms 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

28、 curves, switches, crossings by not allowing the flange of either 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

29、 acceptance tests tests carried out as part of the process and product 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 follo

30、wing information when inviting tenders to supply: a) rail profiles (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.

34、e 7.1 Product integrity 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 requireme

35、nts to achieve the 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 c

36、omplies with EN ISO 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. BS EN 13674

38、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 from the tundish at the time of the

39、 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 all heats shall be tested in the r

40、ail form. Table 2 Hydrogen content of heats Heats Hydrogen content 10-4% (ppm) 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 comply with the requirements of T

41、able 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 testing of rails is required rail samp

42、les 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 the centre of the rail head. If an

43、y 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 grinding off 0,5 mm approximate

44、ly 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. BS EN 13674-3:2006+A1:2010EN 13674-3:2006+A1:2010 (E) 8 8.4

45、Profile tolerances The nominal 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. 8

46、.5 Straightness and twist The tolerance for straightness shall be 1,5 mm over any length of 1,5 m in any plane. If the rail shows evidence of twist on an inspection bed, it will be checked by inserting feeler gauges between the base of the check rail and the rail skid nearest the rail end. If the ga

47、p 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. BS EN 13674-3:2006+A1:2010EN 13674-3:20
