EN 13230-3:2009 (E) 5 Introduction This part of the standard defines the specific requirements dedicated to twin-block reinforced sleepers. These are additional requirements to EN 13230-1:2009 and are necessary to have a complete standard dealing with twin-block reinforced sleepers. The document specifies the test arrangements and the test procedures to implement and also the corresponding acceptance criteria just as the design approval tests It also specifies the steel connecting bar characteristics and the design criteria for incorporating the steel connecting bar within the twin-block reinforced sleepers.
