One aspect of the standard, which is a complete break from tradition, is the inclusion of quality assurance and inspection clause as part of product integrity. In order that quality management systems are consistent across all manufacturers and that users have the best assurance for the consistency of required product quality on this safety critical component of the track, the rail standard requires that the manufacturer’s quality assurance systems are at least equivalent to the requirements of EN ISO 9001. The inclusion of this requirement also reduces the need to incorporate detailed method and calibration descriptions on items such as normal chemical composition determination and the need to define more extensive testing.

If for asymmetric rails hot stamping every 5 m is not practical, the identification of the rail shall be secured by hot stamping or rotary burr near one end of the rail. NOTE 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. The identification system employed shall be such as to enable the hot stamped marking to be collated with: 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). In the event of identification marks having been removed, omitted or requiring alteration, re-identification of such marks shall be made by rotary burr. 7.4.3 Cold stamping Cold stamping shall only be used on the cut face of the rail within the central portion of the head, at the request of the purchaser. 7.4.4 Other identification The steel grade may additionally be identified using paint. The purchaser shall specify the colour and position of the paint application. SIST EN 13674-2:2006+A1:2010

Also all blooms made before the hydrogen content eventually complies with the requirements in Table 3a) must be slowly cooled or isothermally treated. When testing 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 the centre of the rail head. If any test result after the corrective treatment of group 2 rails fails to meet the requirements stated in Table 3a) the heat shall be rejected. 9.1.2.3 Determination of total oxygen content 9.1.2.3.1 General Total oxygen content shall be determined in the liquid steel, following solidification of the sample, or from the solid rail head, in the positions shown in Figure 2, and at the frequency shown in Table 2. The results obtained shall comply with the values given in Table 3a). 9.1.2.3.2 Preparation of the sample The thickness of the transverse rail slice shall be 4 mm. Samples shall be prepared in accordance with EN 10276-1. 9.1.2.3.3 Measurement The measurement of total oxygen shall be made using an automatic machine. 9.1.3 Microstructure 9.1.3.1 General Microstructures shall be determined at a magnification of x 500. The microstructure shall be verified for R260Mn, R260Cr, R320Cr and heat treated rails at the frequency given in Table 2. The testing position in the rail head shall be as shown in Figure 3.

In cases of dispute on the results of the automatic technique, rail flatness shall be verified using a straight edge as shown in Table 7.
