DIN EN 13230-3:2016-11

The European Standard EN 13230 "Railway applications - Track - Concrete sleepers and bearers" consists of the following parts - Part 1: General requirements - Part 2: Prestressed monoblock sleepers - Part 3: Twin-block reinforced sleepers - Part 4: Prestressed bearers for switches and crossings - Part 5: Special elements - Part 6: Design and is used as a technical basis for transaction between corresponding parties (purchaser - supplier). Part 3 of the EN 13230 series of standards defines the specific requirements relating to twin-block reinforced sleepers. These are additional requirements to EN 13230-1 that are necessary to have a complete standard dealing with twin-block reinforced sleepers. The document specifies the test arrangements and 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 and defines technical criteria and control procedures for manufacturing and testing twin-block reinforced sleepers. This document (EN 13230-3) has been prepared by Technical Committee CEN/TC 256 "Railway applications", the secretariat of which is held by DIN (Germany). The responsible German committee Subcommittee NA 087-00-01-03 UA "Gleis- und Weichenschwellen" ("Sleepers and bearers") at DIN Standards Committee Railway (FSF). This standard differs from DIN EN 13230-3:2009-10 as follows: The term "design bending moment" has been replaced by "characteristic bending moment" and "test bending moment".
