This European Standard shall be given the status of a national standard, either by publication of an identical t

20、ext or by endorsement, at the latest by October 2009, and conflicting national standards shall be withdrawn at the latest by October 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held respon

21、sible for identifying any or all such patent rights. The purpose of this standard is to unify the restoration of rail electric arc welding across Europe. The standard provides control systems for the approval and qualification of welding processes, welding procedures, welding consumables, contractor

22、s and welders for the successful delivery of welds into track. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of the EU Directive 2008/57/EC. For relationship with the EU Directive 2

23、008/57/EC, see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denma

24、rk, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. Introduction Restoration of rails by electric arc welding is a

25、 special process requiring the co-ordination of welding and grinding activities to establish confidence and reliability of the weld deposit and safety of the line. Controls must be in place from the design phase through to inspection. Incorrect selection of materials, consumables or procedure may re

26、sult in serious track welding failure. The correct application of the approved processes and the types of repairs permitted to be carried out on various rail components will be strictly adhered to. Only consumables approved by the method described in this standard are to be used. The tasks and respo

27、nsibilities of personnel involved in restoration e.g. planning, executing, supervising and inspection will be clearly defined. BS EN 15594:2009EN 15594:2009 (E) 5 1 Scope This European Standard specifies restoration by electric arc welding and is limited to the head of the rails only. This European

28、Standard describes the approval systems for consumables and procedures used in manual metal arc and flux cored metal deposit rail repair welding. The standard includes the quality-related tasks and responsibilities of personnel involved in the electric arc repair welding of rails. The standard appli

29、es to plain rail and switches and crossings manufactured from new vignole railway rails R200, R220, R260, R260Mn, R260Cr and R350HT grade rails of 46 kg/m and above as contained in EN 13674-1 and EN 13674-2. The permitted welding processes are limited to Electric Arc (EA) in accordance with EN ISO 4

30、063 and are by description Process No 111: MMA (Manual Metal Arc) and Process No 114: FCAW (Flux Cored Arc Welding). This European Standard may be applied in situ, at line side or at out of track locations. The flash welded leg ends of austenitic manganese steel crossings are included in this standa

31、rd, except when located within 500 mm of manganese crossings. 2 Normative references The following referenced documents are indispensable for the application of this document.
