BS EN 13848-3:2009EN 13848-3:2009 (E) 4 1 Scope This European Standard specifies the minimum requirements that shall be met by measuring systems fitted on track construction and maintenance machines to give an evaluation of track geometry quality when measuring
20、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 which the machine or its measuring system is used. It also sets out the acceptable differenc
21、es 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 machines from one year after the date of implementation of this standard. 2 Normative references

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 be extended proportionally (in the ratio of sampling distance: 0,5 m).

NOTE 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 be extende

45、es, 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 machines. Requirements differing from EN 13848-1 are highlighted in bold. The requirements of EN 13848-1 are shown only
