16、07 (E) 3 Foreword This document (EN 13232-8:2007) 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
17、, at the latest by September 2007, and conflicting national standards shall be withdrawn at the latest by September 2007. This European Standard has been prepared under a mandate given to CEN/CENELEC/ETSI by the European Commission and the European Free Trade Association to support Essential Require
18、ments of EU Directives 96/48, as modified by EU Directive 2004/50 of 29 April 2004. For relationship between this document and the Essential Requirements of EU Directive 96/48/EC of the European Parliament and of the Council of 23 July 1996 on the interoperability of the trans-European high-speed ra
19、il system, as modified by EU Directive 2004/50/EC of 29 April 2004, see informative Annex ZA, which is an integral part of this document. This series of standards “Railway applications Track Switches and crossings” covers the design and quality of switches and crossings in flat bottomed rail. The li
20、st 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
21、 Part 9: Layouts Part 1 contains terminology used throughout all parts of the standard. Parts 2 to 4 contain basic design guides and are applicable to all switch and crossing assemblies. The latter parts, from 5 onwards, deal with particular types of equipment, including their tolerances. Part 9 def
22、ines the functional and geometric dimensions and tolerances for layout assemblies. These use Parts 1 to 4 as a basis. 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 Pu
23、rchaser of the equipment on the Users behalf. Supplier The body responsible for the use of the EN in response to the Customers requirements.

26、rail movement of two adjacent rails, while maintaining correct guidance and support. These longitudinal movements may be required in: a) interrupted CWR (continuously welded rail); b) structure movement; c) or a combination of both.

28、tuent parts; to formulate codes of practice for inspection and tolerances; to define the method by which expansion devices and their parts should be identified and traced. 2 Normative references The following referenced documents are indispensable for the application of this document.
