This document has been prepared under two mandates given to CEN by the European Commission and the European Free Trade Association and supports essential requirements of EU Directive(s) For relationship with EU Directive(s), see informative annex ZA which is an integral part of this document. This European Standard is one of the series EN 13230 "Railway applications -Track  Concrete sleepers and bearers" which consists of the following parts:  Part 1: General requirements;  Part 2: Prestressed monobloc sleepers;  Part 3: Twin-block reinforced sleepers;  Part 4: Prestressed bearers for switches and crossings;  Part 5: Special elements. The following terms are used in the standard to define the parties involved in using the EN as the technical bases for a transaction:  purchaser: the operator or user of the equipment or the purchaser of the equipment
on the user’s behalf;  supplier: the body responsible for the use of the EN in response to the purchaser’s requirement. The supplier is also responsible for requirements which apply to the producer or manufacturer. Annexes A, B, C, D and E are informative. This document contains bibliographical references. No other European Standard is superseded or replaced by this European Standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. SIST EN 13230-1:2004

Scope This part of prEN 13230 defines technical criteria and control procedures which have to be satisfied by the constituent materials and the finished concrete sleepers and bearers, i.e.: precast concrete sleepers, bearers for switches and crossings, and special elements for railway tracks. The main requirement of concrete sleepers and bearers is the transmission of vertical, lateral and longitudinal loads from the rails to the ballast or other support. In use, they are also exposed to moisture which can result in detrimental chemical reactions within the sleeper and to frost damage. In this standard, mechanical tests are defined which provide assurance of the capability of sleepers or bearers to resist repetitive loading and provide sufficient durability. In addition, controls are introduced in the manufacturing process and tests set out which will ensure that the concrete will not suffer degradation in service through chemical reaction and frost damage. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

The track is an assembly of transverse concrete sleepers or bearers secured to the rails by means of a fastening system and supported by the ballast or other support. It is characterized by the gauge of the track, the rail profile, the inclination of the rails and the spacing of the concrete sleepers and bearers. 4.2 Loading 4.2.1 Loads The track is subjected to repeated loads in three different directions, generally applied simultaneously: - vertical loads depending on support conditions,
- transverse loads from guiding forces, transverse resistance, etc. - longitudinal loads from acceleration and braking, thermal stresses in continuous welded rail, etc. SIST EN 13230-1:2004
