This European Standard specifies the minimum requirements for measuring systems fitted on Track Construction and Maintenance Machines to give an evaluation of track geometry quality when they measure any one or more of the parameters described in EN 13848-1. This European Standard also gives the acceptable differences from EN 13848-1 when using chord measurements. This European Standard does not specify: - requirements for vehicle acceptance; - criteria for track works acceptance; - requirements for Urban Rail Systems. However, parts of it can be used as a reference until a specific Standard is published. Only systems put into service after the standard comes into force are concerned.
