EN 13232-6:2005 (E) 3 Foreword This European Standard (EN 13232-6:2005) has been prepared by Technical Committee CEN/TC 256 “Railway applications”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2006, and conflicting national standards shall be withdrawn at the latest by March 2006. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. This series of standards “Railway applications – Track – Switches and crossings” covers the design and quality of switches and crossings in flat bottom rails. The list of parts is as follows: Part 1: Definitions Part 2: Requirements for geometric design Part 3: Requirements for wheel/rail interaction Part 4: Actuation, locking and detection Part 5: Switches Part 6: Fixed common and obtuse crossings Part 7: Crossings with moveable parts Part 8: Expansion devices Part 9: Layouts Part 1 contains terminology used throughout all parts of this European Standard. Parts 2 to 4 contain basic design guides and are applicable to all switch and crossing assemblies. Parts 5 to 8 deal with particular types of equipment, including their tolerances. These use parts 1 to 4 as a basis. Part 9 defines the functional and geometrical dimensions and tolerances for layout assembly. The following terms are used within to define the parties involved in using the EN as the technical basis for a transaction: CUSTOMER The operator or user of the equipment, or the purchaser of the equipment on the user's behalf. SUPPLIER The body responsible for the use of the EN in response to the customer's requirements.
EN 13232-6:2005 (E) 4 According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
