This document specifies the minimum requirements for track geometry measuring principles and track geometry measuring systems in order to produce comparable results when measuring the same track.

Only systems put into service after the standard comes into force are concerned. This document does not define the requirements for vehicle acceptance. This document does not apply to measuring systems dedicated to Urban Rail Systems.
