DIN EN 13848-4:2012-03

This part of the European Standard series specifies the minimum requirements that shall be met by measuring systems fitted on track geometry measuring trolleys and manually operated devices to give an evaluation of track geometry quality when measuring one or more of the parameters described in EN 13848-1:2003+A1:2008. It sets out the differences of the requirements from EN 13848-1:2003+A1:2008 (Characterisation of track geometry) when using track geometry measuring trolleys and manually operated devices to measure track geometry. Potential users of this standard are rail measurement technology manufacturers and service persons of railway infrastructure companies. Advantages for the user of this standard are European harmonized requirements for the rail measurement technology for the achievement of comparable results during the assessment of the geometric quality. The European use of terms for the essential parameters defining the position of the track is harmonized. The devices described in DIN EN 13848-4 are also used in public transport (for example, trams).
