NBN EN 13775-2:2003

This European Standard specifies requirements for measuring freight wagons with bogies. This ensures that the measuring processes are applied in accordance with uniform criteria. It applies to new and modified freight wagons with bogies. Provisions going beyond the scope of these requirements should be agreed upon by the contracting parties involved.
The measuring processes relate to the whole or parts of the underframes with or without add-ons if the geometrical structure does not permit anything else. Where appropriate, other measuring methods not specified here are necessary and should be specified in each individual case. This applies as appropriate to bogies.
