EN 13674-1:2003 (E)5IntroductionThis Introduction provides an explanation of the concepts, and reasoning used in the production of this standard.Its inclusion also ensures that during future revisions restrictions are removed as technology progresses and tohold them where it has not, thus ensuring continued safety as new producers, products and technologies areintroduced.The most commonly used standards of the world for the supply of railway rails have been reviewed during thepreparation of this standard. However, modern rail production technology and the requirements of high speedrailways within the Community have demanded a completely new look at the philosophy and content of this part ofEN 13674.Whenever possible this part of EN 13674 is performance based, recognises the European Quality System standardEN ISO 9001 and requires manufacturers to offer the latest proven technology to consistently satisfy thedemanding quality of the required product.This part of EN 13674 has two major divisions:1) qualifying tests;2) acceptance tests.The qualifying tests introduce a number of performance requirements not previously seen in national orinternational standards. They also include typical results from relevant acceptance tests.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 ofrelevance 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 areincluded. The standard includes rail profiles for 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.The standard supersedes other standards covered by the scope and applies to all procurements falling inside therequirements of the European Procurement Directive (93/38/EEC of 14th June 1993). In addition CEN required,where possible, a performance based standard, taking into account safety implications and at the same timeaddressing modern production technology and the requirements of high-speed railways. As a result of the Directiveit was recognised that there would be few opportunities (and these would have to be for transparent safetyconsiderations) for derogation from the standard to operate between the user and the manufacturer.The standard reflects this change in philosophy from the traditional content of rail standards. A review wasundertaken of the most commonly used rail standards of the world. All relevant aspects important to both user andmanufacturer were considered with the aim of ensuring that all of the content had specific usefulness andrelevance. For example rail grading and much of the standard has been based on hardness rather than tensilestrength. Whilst the two are directly related, hardness is very quick and cheap to carry out and provides morerelevant 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 aprerequisite 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 fracturetoughness, fatigue and residual stress. To provide users with the necessary confidence, acceptance limits havebeen 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 andinspection clause as part of product integrity.SIST EN 13674-1:2004
EN 13674-1:2003 (E)6In order that quality management systems are consistent across all manufacturers and that users have the bestassurance for the consistency of required product quality on this safety critical component of the track, this railstandard recommends that the manufacturers' quality assurance systems are at least equivalent to therequirements of EN ISO 9001. The inclusion of this requirement also reduces the need to incorporate detailedmethod and calibration descriptions on items such as normal chemical composition determination and the need todefine more extensive testing.Ideally, manufacturing techniques should not be referenced in a product standard. However, some rail attributesare either not known in an exact manner or are not measurable with satisfactory statistical significance. In suchcases best practice manufacturing techniques have been included as a last resort.
The equipment specified is thatwhich gives the best probability of achieving the required product for use in track.
In the future new technology canadd 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.SIST EN 13674-1:2004
