scope:

This part of ISO/TS 14907 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 (C.1-C.2), an example is given for testing of a complete EFC 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 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, see Figure 1.
