This document 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 for electronic fee collection (EFC) applications.

It defines tests for assessment of OBU conformance in terms 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,

— 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.

After the tests of isolated data items and functions (C.2 to C.4), an example is given for testing of a

complete EFC transaction (C.3).

Whereas this document defines examples of test cases for DSRC and EFC functionality in Annex C, it does

not intend to specify a complete test suite for a certain implementation. To compose a test suite for a

specific EFC implementation, the test cases may have to be modified and new test cases may have to be

defined and added for the conformance test suite to be complete. It can be useful to consider the following

when defining a complete test suite:

— small range: “exhaustive testing” of critical interoperability/compatibility features,

— large range: testing of boundaries and random values, and

— composite types: testing of individual items in sequence or parallel.

It is outside the scope of this document to define tests that assess

— performance,

— robustness, and

— reliability of an implementation.

NOTE 1 ISO 14907-1 defines test procedures that are aimed at assessing performance, robustness and reliability

of EFC equipment and systems.

NOTE 2 The ISO/IEC 10373 series defines test methods for proximity, vicinity, integrated circuit(s) cards and

related devices that may be relevant for OBUs that support such cards.

Annex D provides an informative overview of Japanese OBE conformance tests that are based on the ISO

14907 series, in order to illustrate how these can be applied in practice.
