DIN EN 13232-8:2012-01 EN 13232-8:2007+A1:2011 (E) 5 Introduction An

26、expansion device is a device which permit 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. DIN
