Foreword
This document (prEN 13232-8:2014) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13232-8:2007+A1:2011.
This series of standards “Railway applications – Track – Switches and crossings for Vignole rails” covers the
design and quality of switches and crossings in flat bottomed rail. 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 series. 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 geometric
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.
prEN 13232-8:2014 (E)
Introduction
An expansion device is a device which permits longitudinal relative 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.
prEN 13232-8:2014 (E)
1 Scope
This part of EN 13232 covers the following subjects: to establish a working terminology for expansion devices,
for their constituent parts and for the types; to specify the minimum manufacturing requirements for expansion
devices and their constituent 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.
