BS EN 14811:2006+A1:2009EN 14811:2006+A1:2009 (E) 4 Introduction This introduction provides an explanation of the concept and reasoning for preparing this standard. Its description ensures that, during any future rev
23、isions, 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. The most commonly used delivery conditions in Europe for the supply of grooved rails and associa
24、ted 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 that the technical requirements for the products specified in EN 14811 be reconsidered. Whene
25、ver 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 the demanding quality of the required product. The steels are classified according to hardness
26、 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 importance for the production of grooved rails and associated construction rail profiles and which c
27、omply 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 standard contains profiles for grooved rails and associated construction rail profiles for grooved
28、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 procurements covered by the European Procurement Directive (93/38/EEC of 14 June 1993). Additionally,
29、 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 (and with respect to safety requirements also shall be) options to deviate from the standard u
30、pon 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 rail profiles. The most frequently used delivery conditions in Europe for the supply of grooved
31、 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 appropriate and relevant for the European Standard. For example, the classification of the steel g
32、rades 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, hardness testing is very quick and inexpensive to carry out and provides more relevant guidance to
33、 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 the product integrity. In order to ensure that the quality management systems are consistent fo
34、r 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 management system at least equivalent to the requirements of EN ISO 9001. This makes it possible
35、to dispense with detailed requirements on tests and comprehensive testing. BS EN 14811:2006+A1:2009EN 14811:2006+A1:2009 (E) 5 Ideally, manufacturing methods should not be referred to in product standards. However, some rail properties are either not exactly known or cannot be determined with an ade
36、quately 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 the maximum probability that the necessary product is obtained in the track. Future technolog
37、ical 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 hydrogen content; minimum area reduction for rolling of grooved rails and associated construc
38、tion rail profiles; roller straightening effects on contact scrub. BS EN 14811:2006+A1:2009EN 14811:2006+A1:2009 (E) 6 1 Scope This European Standard specifies requirements for grooved rails and associated construction rail profiles for grooved rail facilities with a linear mass of 42 kg/m and upwar
39、ds 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 either non-heat-treated or heat-treated and are made from non-alloyed (C-Mn) steel in both
40、 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 grooved rail classes are specified differing in requirements for profile tolerances. 2 Norma
