CEN ISO/TS 17444-1:2012

ISO/TS 17444-1:2012 defines metrics for the charging performance of electronic fee collection (EFC) systems in terms of the level of errors associated with charging computation.ISO/TS 17444-1:2012 is a toolbox standard of metrics. The detailed choice of metrics depends on the application and the respective context. ISO/TS 17444-1:2012 describes a set of metrics with appropriate definitions, principles and formulations, which together make up a reference framework for the establishment of requirements for EFC systems and their later examination of the charging performance.
