These are additional requirements to EN 13230-1:2009 and are necess
26、ary 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 a
27、nd the design criteria for incorporating the steel connecting bar within the twin-block reinforced sleepers.
