NOTE The sequence of the branding marks is at the discretion of the manufacturer. 7.4.2 Hot stamping In addition to the branding requirements of 7.4.1 each rail shall be identified by a numerical and/or alphabetical code system, hot stamped on the non-branded side of the rail web by machine and each rail shall be hot stamped at least once every 10 m. !NOTE 1 A rail can display different indications of position of the rail in the bloom (A,B…Y) along its length." !NOTE 2" Subsequent cutting could result in more than one rail length having the same identity. The figures and letters used shall be clearly legible and shall be 16 mm high. The stamped characters shall have a flat or radius face (1 mm to 1,5 mm wide) with bevels on each side. The letters and numbers shall be on a 10° angle from vertical and shall have rounded corners. The stamping shall be between 0,5 mm and 1,5 mm in depth along the centre of the web. The design shall be as shown in Figure 1.
Figure 1 — Design of letters and numbers on a 10° angle for rail stamps The identification system employed shall be such as to enable the hot stamped marking to be collated with the: a) number of the heat from which the rail has been rolled; b) number of the strand and position of bloom within the strand; c) position of the rail in the bloom (A, B . Y). SIST EN 13674-1:2011+A1:2017

NOTE In some circumstances*QK values can be used for the purpose of qualification, see B.6. 8.3 Fatigue crack growth rate 8.3.1 Test method Tests shall be carried out in accordance with the general requirements of ISO 12108. 8.3.2 Test pieces A three point bend, single edge notch test piece, of the dimensions and location within the rail shown in Figure 2 shall be used. 8.3.3 Number of tests and test conditions A minimum of 3 tests from each sample rail shall be performed under the following conditions: — test temperature shall be within the range +15 °C to +25 °C; — R = 0,5 (R = minimum cyclic load/maximum cyclic load); — 3 point bend test piece loading span shall be 4 W (see Figure 2); — cyclic loading frequency shall be within the range 15 Hz to 40 Hz; — environment: laboratory air. 8.3.4 Qualifying criteria Fatigue crack growth rates (m/Gc) shall not exceed the values given in Table 3.

8.4 Fatigue test 8.4.1 Test method Constant amplitude fatigue tests shall be carried out in accordance with ISO 1099. 8.4.2 Test pieces The test pieces shall be machined from the sample rail as shown in Figure 3. 8.4.3 Number of tests and test conditions A minimum of 3 test pieces shall be tested from each sample rail under the following conditions: — test temperature shall be within the range + 15 °C to + 25 °C; — control variable shall be axial strain amplitude; — strain cycle shall be symmetrical about the initial, zero load. 8.4.4 Qualifying criteria For a total strain amplitude of 0,001 35, the life of each specimen shall be greater than 5 × 106 cycles. NOTE Life is defined as the number of cycles up to the complete separation of the specimen. 8.5 Residual stress in rail foot 8.5.1 Test method The residual stresses in the rail foot shall be determined in accordance with Annex C. 8.5.2 Test pieces Each of the 6 test pieces from the rail section shall be 1 m in length and shall be taken from rails as described in 8.1.3 and 8.1.5. NOTE Only a small part of the test piece will be destroyed for the purpose of measuring residual stress; the remainder can be used for other qualifying approval tests. 8.5.3 Measurements Longitudinal residual stress determinations shall be made on the rail foot of each of the 6 test pieces described in 8.5.2. The location of the measurements is shown in Figure C.1. If data are available for straightness class A rails then class B rails of the same profile need not be tested. 8.5.4 Qualifying criteria The maximum longitudinal residual stress in the foot shall be 250 MPa for all steel grades.
