The maximum tolerances specified in Table 1 apply to ballasted track and can be varied by the purchaser in the case of special requirements such as dedicated concrete elements for ballastless track or use of a sleeper laying machine, etc. Table 1 — Maximum tolerances Dimensions Description Tolerances L Overall length of the concrete element ± 10 mm b1, b2 Top and bottom width of the concrete element ± 5 mm hr Depth at any position along the total length of the reinforced concrete element measured in accordance with the quality plan −+310 mm hp Depth at any position along the total length of the prestressed concrete element measured in accordance with the quality plan −+35 mm L1 Distance between the rail fastening gauge points −+12 mm L2 Position of the rail fastening gauge point with regard to the end of the concrete element ± 8 mm L3 Total length of reinforced concrete block ± 8 mm i Inclination of the rail seat (see Annex D) ± 0,25° f Planeness of each rail seat area: with regard to 2 points 150 mm apart (monoblock and twin-block sleepers only) 1 mm T Relative twist between rail seats for monoblock sleepers (see Annex D) 0,5° SIST EN 13230-1:2009

The design, dimensions and tolerances of the fastening system shall be defined by the purchaser. The purchaser shall specify the minimum clearances between rail fastening component and reinforcement according to the fastening system to be used, and between reinforcement and connecting bar for twin-block sleepers. 6.1.2 Concrete cover Unless there is an alternative agreement by the purchaser, the minimum concrete cover for prestressing tendons shall be 30 mm from the bottom surface and 20 mm from the other surfaces except at the ends of sleepers and bearers. The minimum concrete cover for reinforcing steels shall be 25 mm from the bottom surface and 15 mm for the rail seat area and 20 mm from the other surfaces, except for the end of spacing bars. 6.1.3 Prestressing system design The supplier shall define all data in relation with the nominal prestressing force, nominal position of each tendon, anchorage system. The position of the centroid of the prestressing shall be within ± 3 mm of the nominal position relative to the rail seat. The individual prestressing tendons shall be within ± 6 mm of the nominal position relative to the rail seat. The total prestressing force shall be applied within ± 5 % of the specified nominal force. 6.1.4 Reinforcing steel design The supplier shall define all data in relation with the design of the reinforcing steel and nominal position in the concrete element. Tolerance for the position of the reinforcing steel shall be within ± 5 mm of the nominal position in all directions. 6.2 Manufacturing process 6.2.1 General requirements Details of production plant and equipment are the responsibility of the supplier. The supplier shall supply to the purchaser a description of the manufacturing process. SIST EN 13230-1:2009
