25、quirements dedicated to prestressed bearers for switches and crossings. These are additional requirements to EN 13230-1:2016 that are necessary to have a complete standard dealing with prestressed bearers for switches and crossings. The document specifies the test arrangements, the test procedures a
26、nd the corresponding acceptance criteria. EN 13230-4:2016 (E) DIN EN 13230-4:2016-11 6 1 Scope This part of the EN 13230 series defines additional technical criteria and control procedures as well as specific tolerance limits related to manufacturing and testing prestressed bearers for switches and
27、crossings with a maximum length of 8,5 m. Bearers longer than 8,5 m are considered as special elements and are covered by EN 13230-5:2016. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

35、 moment capacities with the objective of keeping it straight. 4.2 Positioning of fastening components An area of the concrete section shall be specified by the purchaser to be free from prestressing tendons for the location of fastening components. If required by the purchaser, the design of the bea
36、rer shall provide for the repair or replacement of the embedded fastening components. EN 13230-4:2016 (E) DIN EN 13230-4:2016-11 8 4.3 Tolerances 4.3.1 General The maximum tolerances specified in EN 13230-1:2016, 6.1 apply to concrete bearers. In case of early dimensional inspection of the concrete
37、element, the quality plan shall take into account further shortening of the element. Measurement of tolerances shall be checked not before 48 h after transfer of prestressing forces. 4.3.2 Tolerance of planeness The maximum deviation of the total rail seat or base plate area is as follows: planeness
38、: 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
39、 Tolerance on dimensions A and D (on the same support area): 1,0 mm Tolerance on dimensions B and C (between two separate support 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
40、special requirements and shall be defined on the drawings submitted by the purchaser. These tolerances shall apply to all embedded components with either direct or indirect fastening system.

Bearers shorter than 4 m need not be checked. Maximum allowed deviation is 3 mm on a 3,6 m base. For bearer length above
43、 6 m, maximum allowed deviation is agreed between supplier and purchaser. 4.4 Distance from the end of the bearer to the nearest cast-in component The supplier defines the prestress anchoring area and special care to be taken into account for cast-in components near to the end of the bearer. 5 Produ
