Licensed CopyChinese University of Hong Kong, 13/06/2009 05:17, Uncontrolled Copy, (c) BSI BS EN 13674-1:2003+A1:2007 This British Standard was published under th
2、e authority of the Standards Policy and Strategy Committee on 3 October 2003 BSI 2009 ISBN 978 0 580 60943 5 National foreword This British Standard is the UK implementation of EN 13674-1:2003+A1:2007. It supersedes BS EN 13674-1:2003 which is withdrawn. It also partially supersedes BS 11:1985 which
3、 has been amended accordingly. The start and finish of text introduced or altered by amendment is indicated in the text by tags. Tags indicating changes to CEN text carry the number of the CEN amendment. For example, text altered by CEN amendment A1 is indicated by !“. BS EN 13674-1:2003 applies to
4、all new installations of Vignole (flat bottom) rail sections of 46 kg/m and above. Other Vignole rails of 27 kg/m and above, switch and crossing rails and check rails have been covered by other parts of BS EN 13674. BS 11:1985 has been declared obsolescent following the publication of the other part
5、s of BS EN 13674. This was done in order to facilitate repairs and maintenance of existing track conforming to and unique to BS 11:1985. The UK participation in its preparation was entrusted to Technical Committee RAE/2, Railway track components. A list of organizations represented on this committee
6、 can be obtained on request to its secretary. Additional information In this standard rail grades are based on hardness whereas in BS 11 they are based on tensile strength. The approximate equivalence is shown as follows. BS EN 13674-1 gradeBS 11 grade R220 Normal R260Wearing resisting A R260MnWeari
7、ng resisting B In BS 11, rail sections are identified by a number which is the approximate mass per a unit length of rails in lb/yd. An approximate conversion to kg/m can be made by multiplying the value in lb/yd by 0,49. NOTE The term “Vignole rail” is in common use elsewhere in Europe. It is deriv
8、ed from the name of Charles Blacker Vignoles, an early railway engineer who promoted the use of flat bottom rail. The textual error set out below was discovered when the English language version of EN 13674-1 was adopted as the national standard. It has been reported to CEN/TC 256/SC 1 in a proposal
9、 to amend the text of the European standard. Table 5a) column headed “running surface” to be changed to “Sulfur content”. The permitted range of sulfur content is shown as a percentage by mass in Table 5a) in the column incorrectly headed as “running surface”. This publication does not purport to in
