25、2016 (E) DIN EN 13230-3:2016-11 5 Introduction This part of the EN 13230 series defines the specific requirements dedicated to twin-block reinforced sleepers. These are additional requirements to EN 13230-1:2016 that are necessary to have a complete standard dealing with twin-block reinforced sleepe
26、rs. 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
27、 the twin-block reinforced sleepers.
