ROLLING MILL _______ 98 40E1
(40E1 profile rail rolled 1998, non-alloy rail steel grade R260) 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. 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. 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. 8 Qualification of the manufacturer The manufacturer shall qualify under EN 13674-1:2011+A1:2017, Clause 8 and shall then be qualified for all profiles in this part of EN 13674, provided the qualification was for the profile 60E1, 60E2 or the heaviest produced for the same grade. NOTE The qualifying criteria specified in EN 13674-1 could not be achieved using the rail grades specified in this part of EN 13674. SIST EN 13674-4:2019
