EN 13230-5, Railway applications - Track - Concrete sleepers and bearers – Part 5: Special elements. 3 Special requirements 3.1 Design bending moments The bearers shall be designed with positive and negative design bending moment capacities with the objective of keeping them straight.
3.2 Positioning of fastening components An area of the concrete section shall be specified by the purchaser to be free from pre-tensioned tendons for the location of fastening components. If required by the purchaser, the design of the bearer shall allow the repair or replacement of the cast-in fastening components. SIST EN 13230-4:2004
Measurement of tolerances shall not be checked until 48 hours after the transfer of the prestressing forces. 3.3.1 Tolerance on flatness
The maximum deviations of the total rail seat or base plate area are as follows: flatness: 1 mm; gradient: 0,5 mm per 150 mm. 3.3.2 Tolerances on fastening positioning
The tolerances on the cast-in fastening components positioning shall be measured in accordance with Figure 1.
Figure 1 — Measurement of tolerances on fastening components positioning
Tolerance on dimensions A and D (on the same support area):
+ 1,0 mm Tolerance on dimensions B and C (between two separate supports areas):
+ 1,5 mm Tolerance on distance between the last cast-in component and the end of the bearer (E):
+ 10 mm The tolerances specified above may be varied by the purchaser in case of special requirements and shall be defined on the drawings submitted by the purchaser. These tolerances shall apply to all cast-in components with either a direct or indirect fastening system. SIST EN 13230-4:2004
