BS PD CEN ISO/TS 14907-2:2016 describes tests that verify on-board unit (OBU) conformance ofimplementations of functions and data structures, as defined in the implementation conformancestatement based on ISO 14906:2011/Amd1:2015, for electronic fee collection (EFC) applications. Afterthe tests of isolated data items and functions (C.2 to C.4), an example is given for testing of a completeEFC transaction (C.3).The scope of this part of ISO/TS 14907 comprises definitions of OBU conformance assessment tests of

basic 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 circuitcards (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 interfacelevel, see Figure 1.
