DIN EN 13674-2:2011-01 EN 13674-2:2006+A1:2010 (E) 5 Introduction This introduction provides an explanation of the concepts and reasoning used in the drafting of t
33、his 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 new manufacturers, products and technologies are introduced. The most commonly used standards of the worl
34、d 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 completely new look at the philosophy and content of this part of EN 13674. Whenever possible this part of EN 136
35、74 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 of the required product. Rail grading is based on hardness rather than tensile strength. The acceptance
36、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 covered by this part of EN 13674 reflect trends in railway usage and heat treated rails are included. Th
37、e standard includes rail profiles for switch and crossing rails used in conjunction with Vignole 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 co
38、vered 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 that there would be few opportunities (and these would have to be for transparent safety
39、 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 standards. A review was undertaken of the most commonly used rail standards of the world. All r
40、elevant 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 Standard has been based on hardness rather than tensile strength. Whilst the two are dire
41、ctly 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 not have previously carried out proving trials, the standard includes a prerequisite f
42、or 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 (see EN 13674-1). To provide users wit
43、h 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 integ
44、rity. 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 manufacturers quality assurance systems ar
45、e 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. DIN EN 13674-2:2011-
46、01 EN 13674-2:2006+A1:2010 (E) 6 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 not measurable with satisfactory statistical significance. In such cases best practice manufacturing techniq
47、ues 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 add to, but preferably will reduce or delete such items. Examples of areas where the technological state of t
48、he 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.
