EN 13230-4:2009 (E) 4 Introduction This part of EN 13230 defines the specific requirements dedicated to prestressed bearers for switches and crossings. These are additional requirements to EN 13230-1:2009 and are necessary to have a complete standard dealing with prestressed concrete bearers for switches and crossings. The document specifies the test arrangements and the test procedures to implement and also the corresponding acceptance criteria just as the design approval test. SIST EN 13230-4:2009
EN 13230-4:2009 (E) 5 1 Scope This part of EN 13230 defines additional technical criteria and control procedures as well as specific tolerance limits related to designing and manufacturing prestressed bearers for switches and crossings with a maximum length of 8,5 m. Bearers longer than 8,5 m are considered as special elements and shall comply with EN 13230-5. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

If required by the purchaser, the design of the bearer shall provide for the repair or replacement of the embedded fastening components. 4.3 Tolerances 4.3.1 General The maximum tolerances specified in EN 13230-1:2009, 6.1 apply to concrete bearers. Measurement of tolerances shall be checked not before 48 h after transfer of prestressing forces. SIST EN 13230-4:2009
EN 13230-4:2009 (E) 6 4.3.2 Tolerance of planeness The maximum deviation of the total rail seat or base plate area is as follows: planeness: 1 mm; •
Variation of planeness with regard to 2 points 150 mm apart: 0,5 mm
4.3.3 Tolerances of fastening positioning
The tolerances of the embedded 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 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 toler
