BS EN 13674-2:2006+A1:2010EN 13674-2:2006+A1:2010 (E) 5 Introduction This introduction provides an explanation of the concepts and reasoning used in the drafting of this European Standard. Its inclusion also ensures that during future revisions, restrictions
29、 are removed where technology progresses and held where it does not, thus ensuring continued safety as new manufacturers, products and technologies are introduced. The most commonly used standards of the world for the supply of railway rails have been reviewed during the preparation of this European
30、 Standard. However, modern rail production technology within the European Union has demanded a completely new look at the philosophy and content of this part of EN 13674. Whenever possible this part of EN 13674 is performance based, recognises the European Quality System standard EN ISO 9001 and req
31、uires manufacturers to offer the latest proven technology to consistently satisfy the demanding quality of the required product. Rail grading is based on hardness rather than tensile strength. The acceptance tests have been designed to control those characteristics of the rail steel and rail that ar
32、e of relevance to the production of high quality rails and the demands of the railway. The steel grades covered by this part of EN 13674 reflect trends in railway usage and heat treated rails are included. The standard includes rail profiles for switch and crossing rails used in conjunction with Vig
33、nole rails having a linear mass 46 kg/m and above. To ensure the supply of high quality rails, some restrictions on production processes have been imposed. This European Standard supersedes other standards covered by the scope. In addition CEN required, where possible, a performance based standard,
34、taking into account safety implications and at the same time addressing modern production technology. It was recognised that there would be few opportunities (and these would have to be for transparent safety considerations) for derogation from this European Standard to operate between the user and
35、the manufacturer. This European 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 ensu
36、ring that all of the content had specific usefulness and relevance. For example rail grading and much of this European 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 guida
37、nce to the user particularly where properties vary in different parts of the profile. Since many rail manufacturers would not have 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 ti
38、me of tendering. The qualifying tests include all “normal” acceptance test results plus new type-casting features such as fracture toughness, fatigue and residual stress (see EN 13674-1). To provide users with the necessary confidence, acceptance limits have been based on results from rail known to
39、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. In order that quality management systems are consistent across all manufacturers and t
40、hat 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 manufacturers quality assurance systems are at least equivalent to the requirements of EN ISO 9001. The inclusion of this requirement
41、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. BS EN 13674-2:2006+A1:2010EN 13674-2:2006+A1:2010 (E) 6 Ideally, manufacturing techniques should not be referenc
42、ed in a product standard. However, some rail attributes are either not known in an exact manner or are not measurable with satisfactory statistical significance. In such cases best practice manufacturing techniques have been included as a last resort. The equipment specified is that which gives the
43、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; hydro
44、gen test techniques; roller straightening effects on residual stresses; roller straightening effects on contact scrub; measurement and effect of residual stresses throughout the rail. BS EN 13674-2:2006+A1:2010EN 13674-2:2006+A1:2010 (E) 7 1 Scope This part of EN 13674 specifies switch and crossing
45、rails that carry railway wheels. These are used in conjunction with Vignole railway rails. This part of this standard is not applicable for the check rails that do not carry railway wheels. Eight pearlitic steel grades are specified covering a hardness range of 200 HBW to 390 HBW and include non hea
46、t treated non-alloy steels, non heat treated alloy steels, heat treated non-alloy steels and heat treated low alloy steels. There are !34 rail profiles“ specified in this standard, but they may not all be available in all steel grades. Rails specified in EN 13674-1 may also be used as switch and cro
47、ssing rails and if so used they shall comply with the requirements of EN 13674-1. 2 Normative references The following referenced documents are indispensable for the application of this document.
