DIN EN 14811:2010-05 EN 14811:2006+A1:2009 (E) 4 Introduction This introduction provides an explanation of the concept
25、and reasoning for preparing this standard. Its description ensures that, during any future revisions, restrictions will be removed if technical progress has been made or will be kept if this is not the case in order that safety is maintained if new manufacturers, products and technologies appear. Th
26、e most commonly used delivery conditions in Europe for the supply of grooved rails and associated construction rail profiles have been reviewed during the preparation of this standard. Modern rail production technology and the requirements of commuter railways within the European Union have demanded
27、 that the technical requirements for the products specified in EN 14811 be reconsidered. Whenever possible, this EN 14811 is performance-based. It recognizes the European quality management standard EN ISO 9001 and requires manufacturers to offer the latest proven technology consistently to satisfy
28、the demanding quality of the required product. The steels are classified according to hardness and not to tensile strength. The acceptance tests were developed in order to monitor the properties of the grooved rail steels and grooved rails and associated construction rail profiles that are of import
29、ance for the production of grooved rails and associated construction rail profiles and which comply with the demands of commuter railways. The steel grades covered by EN 14811 reflect trends in commuter railway usage and heat-treated rails as well as associated construction rail profiles. This stand
30、ard contains profiles for grooved rails and associated construction rail profiles for grooved rail facilities having a linear mass of 42 kg/m and above. To ensure the supply of high quality rails, some restrictions on production processes have been imposed. This standard is applicable to all procure
31、ments covered by the European Procurement Directive (93/38/EEC of 14 June 1993). Additionally, CEN has requested a performance-based standard taking into account safety requirements and the application of the most recent technologies. With respect to the Directive, it is acknowledged that there are
32、(and with respect to safety requirements also shall be) options to deviate from the standard upon agreement between purchaser and manufacturer. This standard reflects the change in philosophy compared with the traditional content of delivery conditions for grooved rails and associated construction r
33、ail profiles. The most frequently used delivery conditions in Europe for the supply of grooved rails and construction rail profiles have been reviewed. All the aspects that are important for the purchasers and manufacturers have been analysed to ensure that the overall contents are particularly appr
34、opriate and relevant for the European Standard. For example, the classification of the steel grades of grooved rails and associated construction rail profiles and also other aspects of the European Standard has been based on hardness, not on tensile testing. Whilst the two are directly related, hard
35、ness testing is very quick and inexpensive to carry out and provides more relevant guidance to the user, particularly where properties vary in different parts of the profile. One new aspect of the European Standard is the integration of a clause on quality management and testing in order to assure t
36、he product integrity. In order to ensure that the quality management systems are consistent for all manufacturers and that all purchasers can be sure about the consistency of the product quality of these safety-related components, this standard recommends that the manufacturer operates a quality man
37、agement system at least equivalent to the requirements of EN ISO 9001. This makes it possible to dispense with detailed requirements on tests and comprehensive testing. DIN EN 14811:2010-05 EN 14811:2006+A1:2009 (E) 5 Ideally, manufacturing methods should not be referred to in product standards. How
38、ever, some rail properties are either not exactly known or cannot be determined with an adequately high statistical reliability. In these cases, as the final possibility, reference is made to manufacturing methods that correspond to best practice. Methods and requirements are specified that offer th
39、e maximum probability that the necessary product is obtained in the track. Future technological solutions can increase the list of these requirements but will preferably reduce them. Examples of where todays technology is taken as the basis, but developments are progressing, are: determination of hy
40、drogen content; minimum area reduction for rolling of grooved rails and associated construction rail profiles; roller straightening effects on contact scrub. DIN EN 14811:2010-05 EN 14811:2006+A1:2009 (E) 6 1 Scope This European Standard specifies requirements for grooved rails and associated constr
41、uction rail profiles for grooved rail facilities with a linear mass of 42 kg/m and upwards for use in tram transport systems. NOTE Grooved rails are also used for harbour and industrial tracks. Six pearlitic steel grades are specified in a hardness range between 200 HBW and 390 HBW. The rails are ei
42、ther non-heat-treated or heat-treated and are made from non-alloyed (C-Mn) steel in both cases. This standard specifies 18 specific grooved rail profiles and 7 specific construction rail profiles. The grooved rail profiles can also be used as construction elements in switches and crossings. Two groo
43、ved rail classes are specified differing in requirements for profile tolerances. 2 Normative references The following referenced documents are indispensable for the application of this document.
