DIN EN 13674-1:2017-07 EN 13674-1:2011+A1:2017 (E) 7 Introduction This Introduction provides an explanation of the concepts, and reasoning considered for this standard. Whenever possible this part of EN 13674 is performance based, recognises the European Quality Sy
38、stem standard EN ISO 9001 and requires manufacturers to offer the latest proven technology to consistently satisfy the demanding quality of the required product. This part of EN 13674 has two major divisions: 1) qualifying tests; 2) acceptance tests. The qualifying tests take into account performanc
39、e requirements. They also include typical results from relevant acceptance tests. The acceptance tests control those characteristics of the rail steel and rail that are of relevance to the production of high quality rails including heat treated rails and the demands of the railway. To ensure the sup
40、ply of high quality rails, some restrictions on production processes are considered. The performance based standard applies to all procurements falling inside the requirements of the European Procurement Directive (93/38/EEC of 14thJune 1993), taking into account safety implications and at the same
41、time addressing modern production technology and the requirements of high-speed railways. As a result of the Directive it was recognised that there would be few opportunities (and these would have to be for transparent safety considerations) for derogation from the standard to operate between the us
42、er and the manufacturer. The 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“ features such as fracture toughness, f
43、atigue and residual stress. 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. The standard includes a quality assurance and inspection clause as part of product integrity. In order tha
44、t 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, this rail standard recommends that the manufacturers quality assurance systems are at least equi
45、valent 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.

46、011+A1:2017 (E) 8 1 Scope This European Standard specifies Vignole railway rails of 46 kg/m and greater linear mass, for conventional and high speed railway track usage. Nine pearlitic steel grades are specified covering a hardness range of 200 HBW to 440 HBW and include non heat treated non alloy s
47、teels, non heat treated alloy steels, and heat treated non alloy steels and heat treated alloy steels . There are 23 rail profiles specified in this standard. Two classes of rail straightness are specified, differing in requirements for straightness, surface flatness and crown profile. Two classes o
48、f profile tolerances are specified. 2 Normative references !The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
