29、duction 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 are removed where technology progresses and held where it does not, thus ensuring continued safety as

30、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 Standard. However, modern rail production technology within the European Union has demanded a complete

31、ly 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 requires manufacturers to offer the latest proven technology to consistently satisfy the demanding quality

32、 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 are of relevance to the production of high quality rails and the demands of the railway. The steel grades

33、 covered by this part of EN 13674 reflect trends in railway usage and heat treated rails are included. This European Standard includes rail profiles for Vignole rails having a linear mass from 27 kg/m to, but excluding 46 kg/m. To ensure the supply of high quality rails, some restrictions on product

34、ion processes have been imposed. This European Standard supersedes national standards covered by the scope. In addition CEN required, where possible, a performance based standard, taking into account safety implications and at the same time addressing modern production technology. It was recognised

35、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 the manufacturer. This European Standard reflects this change in philosophy from the traditional content of rail standar

36、ds. 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 this European S

37、tandard 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 woul

38、d not have previously carried out proving trials, this European 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 featu

39、res 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 have performed well in demanding track installations. One aspect of this European Standard, which is a complet

40、e break from tradition, is the inclusion of quality assurance and inspection clause as part of product integrity. DIN EN 13674-4:2010-04 EN 13674-4:2006+A1:2009 (E) 6 In order that quality management systems are consistent across all manufacturers and that users have the best assurance for the consi

41、stency 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 also reduces the need to incorporate detailed m

42、ethod and calibration descriptions on items such as normal chemical composition determination and the need to define more extensive testing. Ideally, manufacturing techniques should not be referenced in a product standard. However, some rail attributes are either not known in an exact manner or are

43、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 best probability of achieving the required product for use in track. In the future new technology can a

44、dd 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

45、 contact scrub; measurement and effect of residual stresses throughout the rail. DIN EN 13674-4:2010-04 EN 13674-4:2006+A1:2009 (E) 7 1 Scope This part of EN 13674 specifies flat bottom Vignole railway rails from 27 kg/m to, but excluding 46 kg/m. Five pearlitic steel grades are specified covering a

46、 rail hardness range of 200 HBW to 390 HBW and include non-heat-treated non-alloy steels, non-heat-treated alloy steels and heat-treated non-alloy steels. There are 13 rail profiles specified in this European Standard, but these may not be available in all steel grades. 2 Normative references The fo
