This document applies to the measurement of vertical wheel forces of railway vehicles in maintenance workshops and at manufacturing sites. It also deals with derived quantities that are used to describe the vehicle’s vertical wheel force distribution. The document defines the assessment and acceptance criteria for the measurement process. The requirements for this assessment support the specification, the design and the operation of the measurement process. It is considered that the measurements are made either statically or quasi-statically. This document is applicable to all railway vehicles. The commercial weighing of vehicles is not covered by the scope of this document, nor does it define in which cases the wheel forces of a vehicle will be measured.
