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 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 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 that
assess 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 assess
performance,
robustness, and
reliability of an implementation.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 14907-2 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.
This second edition cancels and replaces the first edition (ISO/TS 14907-2:2006), which has been technically
revised.
ISO/TS 14907 consists of the following parts, under the general title Electronic fee collection — Test

Part 2:
Conformance test for the onboard unit application interface
1 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 (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, see Figure 1.

ISO/TS 14907-2:2011(E)
Figure 1 — The EFC application interface
The purpose of this part of ISO/TS 14907 is to define tests that
assess 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.
Whereas this part of ISO/TS 14907 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 in order for the conformance test to be complete. It can be useful to take into account
the following considerations 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.
Figure 2 shows the overall procedure of conformance testing.

Figure 3 gives a more detailed picture of the interface between the entity performing the conformance test and
the supplier of the Device Under Test (DUT). By the EFC application specification, the implementation
conformance statement pro forma and the implementation extra information for testing pro forma the supplier
is requested to provide the DUT (OBU), containing the Implementation Under Test (IUT), as well as the
documentation needed to perform the tests. More details on the content of the different documents are given
in Clause 5 on OBU and supporting information.
NOTE 1 The Device Under Test contains the Implementation Under Test.

It is outside the scope of this part of ISO/TS 14907 to define tests that assess
performance,
robustness, and
reliability of an implementation.
NOTE 2 ISO/TS 14907-1 defines test procedures that are aimed at assessing performance, robustness and reliability
of EFC equipment and systems.
NOTE 3 The ISO/IEC 10373 family of International Standards defines test methods for proximity, vicinity, integrated
circuits(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
ISO/TS 14907 suite of standards, in order to illustrate how these can be applied in practice.

5 OBU and supporting information
The supplier shall provide the OBU, i.e. the DUT, and the associated information including:
OBUs personalized to be able to perform tests according to the ICS and IXIT as defined in 5.1 and 5.2,
respectively. At least five samples shall be submitted for test. More samples may be needed if several
different data structures and data contents are required in the tests;
user's manual for the OBU, which shall include instructions how to handle the equipment, and may
include further detailed information about the protocol functions;
implementation conformance statement according to 5.1. The ICS shall include statements regarding the
following:
layer 7 services that are implemented in the OBU;
EFC functions (action types) that are implemented in the OBU;
whether or not data elements are used;
implementation extra information for testing according to 5.2. The IXIT shall, if applicable, include:
a statement regarding which layer 2 services shall be used to transfer the L7 services (and EFC
services);
a description of security calculations in the OBU including a specification of the encryption algorithm
used;

values of the test Master Keys for calculation and verification of OBU security data such as
authenticators and access credentials.
The supplier should also provide configuration/personalization equipment for the OBU if that ensures effective
testing.
5.1 ICS
The ICS is a statement made by the supplier that claims conformance to a certain specification. The ICS
states which capabilities have been implemented in the specifications. It also states possible limitations in the
implementation of the specification.
This Technical Specification describes testing of implementations according to the following standards:
EN 12834;
ISO 14906:2011.
Annex A contains the ICS pro forma that shall be used for the ICS.
5.2 IXIT
The IXIT is a statement made by the supplier or an implementer of an IUT which contains or references all of
the information, in addition to that given in the implementation conformance statement, related to the DUT and
its testing environment. The IXIT enables the test laboratory to run an appropriate test suite against the DUT.
In this Technical Specification, the IXIT specifies the services in the lower communication layers that shall be
used to perform the services to be tested. These services are described e.g. in EN 12795, EN 12253 and
EN 13372.
The IXIT shall also contain further information and describe algorithms and procedures that are not specified
in the above standards but are prerequisites to perform the testing. Example of such information is:
content of the ApplicationContextMark in the VST;
calculation of access credentials in DSRC services;
use of ReturnCode in DSRC L7 services and EFC functions; and
calculation of authenticators in EFC functions.
Annex B contains the IXIT pro forma that shall be used for the declaration of the IXIT.
6 Testing requirements
6.1 Conceptual test architecture
A remote test method shall be used for the conformance test of OBUs (DUT). Figure 4 shows the conceptual
testing architecture of tester and DUT. The conformance test is only related to the implementation of the DUT.
The PoC, which is the point where the test events are controlled, shall be implemented inside the tester on the
interface between the application layer and the application process.
The PoO, which is the
