23、 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 consist of the following parts: Part 1: General requirements; Part 2: Prestressed monoblock sleepers; Part 3: Twin-block reinforced

BS EN 13230-1:2016EN 13230-1:2016 (E) 6 Introduction This part of the EN

28、 13230 series covers the general requirements for concrete sleepers and bearers and is used in conjunction with the following parts: Part 2: Prestressed monoblock sleepers; Part 3: Twin-block reinforced sleepers; Part 4: Prestressed bearers for switches and crossings; Part 5: Special elements; Part

29、6: Design. Concrete sleepers and bearers are safety critical components for railway applications. They are not covered by any other standards. As safety critical components, an agreement is needed between purchaser and supplier to operate a factory Quality System. This position about safety critical

30、 relevance has always been highlighted by decisions from CEN/TC 256/SC 1 “Railway applications / Infrastructure” and Annex ZA provides detailed information. BS EN 13230-1:2016EN 13230-1:2016 (E) 7 1 Scope This part of the EN 13230 series defines technical criteria and control procedures which need t

31、o be satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e.: precast concrete sleepers, twin-block reinforced sleepers, bearers for switches and crossings, and special elements for railway tracks. The main requirement of concrete sleepers and bearers is the trans

32、mission of vertical, lateral and longitudinal loads from the rails to the ballast or other support. In use, they are also exposed to frost damage and to moisture, which can result in detrimental chemical reactions within the sleeper. In this standard mechanical tests are defined which provide assura

33、nce of the capability of sleepers or bearers to resist repetitive loading and provide sufficient durability. In addition, controls are placed on manufacturing processes and tests to ensure that the concrete will not suffer degradation in service through chemical reaction and frost damage. 2 Normativ
