The standard reflects this change in philosophy from the traditional content of rail standards. A review was undertaken of the most commonly used rail standards of the world. All relevant aspects important to both user and manufacturer were considered with the aim of ensuring that all of the content had specific usefulness and relevance. For example rail grading and much of the standard has been based on hardness rather than tensile strength. Whilst the two are directly related, hardness is very quick and cheap to carry out and provides more relevant guidance to the user particularly where properties vary in different parts of the profile.
Since many rail manufacturers would have not previously carried out proving trials, the standard includes a prerequisite for all manufacturers to prove conformity against a set of qualifying test criteria at the time of tendering. The Qualifying tests include all “normal” acceptance test results plus new "type-casting" features such as fracture toughness, fatigue and residual stress. To provide users with the necessary confidence, acceptance limits have been based on results from rail known to have performed well in demanding track installations.
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. SIST EN 13674-1:2004+A1:2008

The equipment specified is that which gives the best probability of achieving the required product for use in track.
In the future new technology can add to, but preferably will reduce or delete such items. Examples of areas where the technological state of the art renders the standard less than complete include:  oxide/oxygen relationships;  hydrogen test techniques;  roller straightening effects on residual stresses;  roller straightening effects on contact scrub;  measurement and effect of residual stresses throughout the rail.

process whereby blooms are held for a period of time at an elevated temperature for diminishing the hydrogen content NOTE 1 For maximum efficiency this is as near to (but below) the pearlite to austenite transformation temperature as is practically possible. NOTE 2 This process is sometimes referred to as sub critical diffusion annealing. 3.8 qualifying tests special tests and criteria which are relevant to some aspects of the service performance of rails. Acceptance tests also form part of the qualifying tests. 3.9 acceptance tests tests carried out as part of the process and product control system, normally on a heat, sequence or tonnage basis 4 Information to be supplied by the purchaser The purchaser shall provide the supplier with the following information at the time of tender or order: a) the rail profile (see annex A); b) the steel grade (see clause 5); c) the profiles class, ‘X’ or ‘Y’ (see 9.2.1); d) the straightness class ‘A’ or ‘B’ of rail as specified in 9.2.2; e) the lengths of rail (see 9.2.3 and Table 10); f) undrilled or drilled rail ends to take fish bolts, and location and dimensions of holes when required (see 9.2.3); g) any special treatments to be applied to bolt holes; h) tolerances for bolt holes to which special processes are to be applied; i) paint code requirements (see 7.4.4).

The tolerances of certain dimensions shall be as given in Table 8. All other quantities are informative only. NOTE Linear masses have been calculated based on the density of steel of 7850 kg/m3. 7 Manufacture 7.1 Product integrity 7.1.1 Factory production control All Vignole 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 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. SIST EN 13674-1:2004+A1:2008

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: a) the number of the heat from which the rail has been rolled; b) the number of the strand and position of bloom within the strand; c) the 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 Rails of straightness class A shall be identified with a green mark and the position of the green mark is to be specified by the purchaser. The steel grade may additionally be identified using paint. The purchaser shall specify the colour and position of the paint application. SIST EN 13674-1:2004+A1:2008

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. 8.6 Variation of centre line running surface hardness of heat treated rails This clause only applies to heat treated rails. For the longest length of rail produced by the manufacturer, a one metre length of rail shall be taken from each end and at 20 m intervals from one end of the rail. These shall be hardness tested (HBW) in accordance with EN ISO 6506-1 along their length at 25 mm intervals on the centreline of the running surface after 0,5 mm has been ground away. The hardness results shall be no more than ± 15 HBW from the mean result obtained. SIST EN 13674-1:2004+A1:2008
