17、pean foreword This document (EN 13230-3:2016) has been prepared by Technical Committee CEN/TC 256 “Railway applications”, the secretariat of which is held by DIN. This document supersedes EN 13230-3:2009. This European Standard shall be given the status of a national standard, either by publication
18、of an identical text or by endorsement, at the latest by November 2016, and conflicting national standards shall be withdrawn at the latest by November 2016. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports
19、essential requirements of EU Directive 2008/57/EC. For relationship with EU Directive 2008/57/EC, see informative Annex ZA, which is an integral part of this document. This European Standard is one of the EN 13230 series “Railway applications Track Concrete sleepers and bearers”, which consists of t

These are additional requirements to EN 13230-1:2016 that are necessary to have a complete standard dealing with twin-block reinfor
24、ced 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
25、bar within the twin-block reinforced sleepers.
