26、rms and definitions apply. 3.1 absolute track position position of the track in reference to an external coordinated system 3.2 acceptance acceptance is the declaration of the customer to the contractor that the work has been achieved in accordance with the contract 3.3 design track gauge single val
27、ue which is obtained when all the components of the track conform precisely to their design dimensions or their median design dimension when there is range. It may differ from nominal track gauge. The design track gauge is specified by the customer taking into account the materials, the method of me
28、asurement and whether the application is on plain line or in switches and crossings 3.4 design track geometry calculated values of track geometric parameters Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 10:57:06 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13231-2:2006 (E) 5 3.5 loaded an

30、moving system 3.8 tolerance permissible deviation from reference or designed value 3.9 track geometry group of parameters defining the position of the rails, usually the following: gauge, alignment, longitudinal level, twist and cant 3.10 works on switches and crossings works on switches and crossin
31、gs cover: initial construction; simultaneous or separated replacement of parts of turnouts (switch rail/stock rail, crossing, etc.), bearers and ballast; tamping / levelling / lining / dynamic track stabiliser (DTS) work to correct track geometry; other works on switches and crossings, excluding wor
32、ks covered by EN 13231-3; welding. 4 Acceptance of works on switches and crossings 4.1 General The requirements under this clause apply to works as defined in 3.10. Related works, e.g. platform reconstruction, formation, drainage, level crossings are not covered by this standard. The acceptance of w
33、elding work in conjunction with switch and crossing works is covered by prEN 14730 (series) when available. An acceptance form shall be prepared for each item of work outlining the results achieved (see an example of this type of form in Annex B). Acceptance is not given until the work is completed
34、in accordance with the requirements of the contract. Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 10:57:06 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13231-2:2006 (E) 6 4.2 Acceptance deadlines Acceptance shall not be carried out until the track has been subjected to an appropriate pass
35、ing tonnage, including the mechanically simulated loading (e.g. by a DTS), which shall be defined by the customer that permits clearance of the track for the maximum permitted speed. It is permitted for acceptance to occur within a period after the completion of the works as defined by the customer
36、(i.e. after receipt of the application from the contractor), even if the appropriate passing tonnage has not been achieved. 4.3 Acceptance measurements and checks Before acceptance, the following measurements or checks shall be carried out when applicable (manually or by automatic means): relative s
37、witch and crossing geometry in the switch and crossing layout; absolute switch and crossing position. Comparison of the actual switch and crossing position with the design position, as defined by the customer; weld measurements (running surface and running edge); measurement of joint gaps and dips;
38、measurement of joint staggers; check of insulated joints; bearer position, voiding of bearers, correct assembly and integrity of the rail fastenings, pads and insulators; check of ballast profile; damage caused to rails, bearers, fastenings, cables and other equipment, or where the work process has
39、displaced the bearers or the rail pads; measurement of geometrical relationship of diverging track to through track; measurement of track gauge and of gauge between the crossing nose and the check rail; measurement of flangeway; measurement of check rail to check rail at Diamond Crossing; measuremen
40、t of switch squareness; measurement of longitudinal relationship of switch tip to stock rail mark; distance between switch rail and stock rail both in closed and open positions. Additional measurements shall be taken for expansion joints: gap and switch position in relation to mark on stock rail; ve
41、rification of free movement of switches; squareness of switch / stockrails. The customer may also request additional measurements or checks if previously agreed.

42、metry shall be measured by a track recording vehicle or where this is not available by a track maintenance machine fitted with measuring equipment, both in accordance with series EN 13848 when available. If the measuring equipment fails, or is not available, corresponding hand or light devices measu
43、rements shall be taken and documented. Other use of hand or light devices measurements shall be previously defined by the customer. The customer shall previously agree all measuring equipment in track recording vehicles, maintenance machines and hand or light devices measurements. For the purpose of
44、 acceptance, every section shall be inspected by the experts as nominated by the customer and the contractor. The contract shall define who should perform the measurements. 4.4 Acceptance documents All measurements and checks carried out in accordance with 4.3 shall be documented. In addition, the f
45、ollowing documents shall be made available when applicable: record of measurements of the switch and crossing geometry; record of the switch and crossing installation (design/actual comparison) compared with the switch and crossing workshop drawing, and according to the layout acceptance form as des
46、cribed in prEN 13232-9; record of measurements in relation to the setting out drawing (scheme drawing); reports of welding and stressing of switches and crossings (including that of all immediately adjoining track); verification of proper tightening and fitting of rail fasteners; proof of acceptance
47、 of associated works; proof of approval and acceptance of the material provided by the supplier; approval of prefabrication according to Quality system; list of joint-gap measurements; report of the installation of expansion joints; switches and crossings workshop drawing; setting out drawing (schem
48、e drawing). NOTE The customer may also request additional documentation if previously agreed. 4.5 Relative track geometry 4.5.1 Tolerances Accepted track shall comply with the relevant tolerances shown in Tables 1 and 2. The applicable parameters shall be nominated by the customer, according to the
49、scope of the work. The tolerances in Tables 1 and 2 are for loaded measurements. For unloaded measurements of track gauge the customer shall define the value for the design track gauge.
