DIN EN 13848-3:2013-01 EN 13848-3:2009 (E) 4 1 Scope This European Standard specifies the minimum requirements that shall be met by measuring systems fitted on track constructi
22、on and maintenance machines to give an evaluation of track geometry quality when measuring one or more of the parameters described in EN 13848-1. It does not seek to prescribe which parameters are to be measured, since these depend upon the measuring capabilities of the machine and the purpose for w
23、hich the machine or its measuring system is used. It also sets out the acceptable differences from EN 13848-1 when using track construction and maintenance machines to measure track geometry. It applies to track geometry measuring systems which are fitted to track construction and maintenance machin
24、es from one year after the date of implementation of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE 4 For measurements with a sampling distance greater than 0,5 m (see note in 5.5.4.2), the minimum length of the test section should

The test section shall be long enough to ensure that usable data is obtained over 200 continuous metres of track for each run. NOTE For measurements with a sampling d
42、istance greater than 0,5 m (see note in 5.5.4.2), the minimum length of the test section should be extended proportionally (in the ratio of sampling distance: 0,5 m). The manufacturer shall specify the content of the simplified test to be undertaken for any relevant operation of maintenance or repai

At least once per shift, static tests
46、shall be carried out for example to ensure that there are no offsets in the measurement of cross level and track gauge.

47、of the actual equipment on existing machines and as track geometry measurements are not the main functions of machines, the EN 13848-1 requirements have to be relaxed. Therefore, this Annex lists in tabular form the minimum requirements for each track geometry parameter which can be measured by mach
48、ines. Requirements differing from EN 13848-1 are highlighted in bold. The requirements of EN 13848-1 are shown only for comparison purposes.
