CEN ISO/TS 14907-2:2011

ISO/TS 14907-2:2011 describes tests that verify on-board unit (OBU) conformance of implementations of functions and data structures, as defined in the implementation conformance statement based on ISO 14906:2011, for electronic fee collection (EFC) applications. After the tests of isolated data items and functions, an example is given for testing of a complete EFC transaction.ISO/TS 14907-2:2011 comprises definitions of OBU conformance assessment tests ofbasic dedicated short-range communication (DSRC) L7 functionality, EFC application functions, EFC attributes (i.e. EFC application information), the addressing procedures of EFC attributes and (hardware) components [e.g. integrated circuit cards (ICC) and man-machine interfaces (MMI)], the EFC transaction model, which defines the common elements and steps of any EFC transaction, and the behaviour of the interface so as to support interoperability on an EFC-DSRC application interface level. It also defines tests thatassess OBU capabilities, assess OBU behaviour, serve as a guide for OBU conformance evaluation and type approval, achieve comparability between the results of the corresponding tests applied in different places at different times, and facilitate communications between parties. It is outside the scope of ISO/TS 14907-2:2011 to define tests that assessperformance, robustness, and reliability of an implementation.
