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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
For an electronic fee collection (EFC) system, approvals and tests are required to determine whether the
system (or individual components of the system) conforms to standards and application requirements and
to enable parameters such as quality, availability, and maintainability to be measured.
This document provides a toolbox of tests and procedures for the assessment and proof of EFC systems
that they are suitable for specified EFC applications under specific operational conditions. Depending on
the system to be tested and based on available documentation and the status of previous approvals, this
document helps interested parties, such as system suppliers, operators and testing institutes, make use of
already proven references and identify parameters that still need to be tested according to the specified
intended use.
At the time of publication of this document, the determination of common system requirements for Europe
(or any other region) has not been agreed. For this reason, no specific performance requirements are set
out in this document, unless these are already determined elsewhere (such as safety or radio regulations),
but instead the most important parameters that should be included in such requirements specifications are
stated. Where reference to an existing test is available, this document provides that reference. This document
defines only the test and test procedures, not the benchmark figures that these are to be measured against.
Benchmark figures which the systems or components under test can be compared with and validated
against might form the subject of a future part of this series of standards. Within the framework of the
European Electronic Toll Service (EETS), this document may provide a basis for the certification of the
various systems' part of the EETS, in particular for assessing their suitability for use.
This document is furthermore limited to automated (electronic) payment using a standardized dedicated
short-range communication (DSRC). The scope of this document does not include manual payment,
conventional money transaction, nor payment by means of sticker, vignettes, tickets, or magnetic-stripe
cards, etc. The applications to which EFC is related are toll collection, road pricing, parking, and individual
traffic information.
This document supports groups of operators to determine common specific performance levels and operating
conditions, whilst allowing for regional variation where needed. It provides operating and environmental
parameters (or classes of operating and environmental parameters) within which such systems operate
without impairing interoperability.
The following guidelines have been followed when selecting the test procedures for test parameters:
— reference as far as possible to existing standardized test procedures;
— focusing on those tests that are essential to ensure that EFC equipment can exchange information and
mutually use the exchanged information.
An overview of the tests and parameters provided by this document is given in 5.1 and 5.2.
A brief guide describing how to use this document is provided by Annex A.
Whilst this document relates to general test procedures, some provisions relate specifically to test
procedures for certification purposes Many parts of this document are relevant internationally, but
adaptations may be needed to meet regulations outside Europe before it can be accepted as an international
standard like in the EU.
ISO/TS 37444 provides an examination framework for EFC charging performance.

DRAFT International Standard ISO/DIS 14907-1:2025(en)
Electronic fee collection — Test procedures for user and fixed
equipment —
Part 1:
Description of test procedures
1 Scope
This document specifies the test procedures for roadside equipment (RSE) and on-board equipment (OBE)
for electronic fee collection (EFC) with regard to the conformance to standards and requirements for type
approval and acceptance testing.
The scope of this document is restricted to systems operating within the radio emission, electromagnetic
compatibility (EMC) regulations, traffic, and other regulations of the countries in which they are operated.
This document identifies a set of suitable parameters and provides test procedures to enable the proof of a
complete EFC system, as well as components of an EFC system, e.g. OBE, related to the defined requirements
of an application. The defined parameter and tests are assigned to the following groups of parameters:
— functionality;
— quality;
— referenced pre-tests.
This document describes procedures, methods and tools, and a test plan which shows the relation between
all tests and the sequence of these tests. It lists all tests that are required to measure the performance
of EFC equipment. It describes which EFC equipment is covered by the test procedures; the values of the
parameters to be tested are not included. It also describes how the tests are to be performed, and which
tools and prerequisites are necessary before this series of tests can be undertaken. It is assumed that the
security of the system is inherent in the communications and EFC functionality tests, therefore they are not
addressed here. All tests in this document provide instructions to how to evaluate the test results.
This document defines only the tests and test procedures, not the benchmark figures that these are to be
measured against. The test procedures defined in this document can be used as input, e.g. by scheme owners,
for prototype testing, type approvals, tests of installations and periodic inspections.
Related to a conceptual model of an EFC system, this document relates only to the equipment of the user and
the service provider.
EFC systems for dedicated short-range communication (DSRC) consist, in principle, of a group of technical
components, which in combination fulfil the functions required for the collection of fees by electronic
automatic means. These components comprise all, or most, of the following:
— OBE within a vehicle;
— OBE containing the communications and computing sub-functions;
— optional integrated circuit card which may carry electronic money, service rights, and other secured
information;
— communication between OBE and RSE based on DSRC;
— equipment for the fee collection at the RSE containing the communications and computing sub-functions;

ISO/DIS 14907-1:2025(en)
— equipment for the enforcement at the roadside;
— central equipment for the administration and operation of the system.
The scope of this document relates solely to OBE and RSE and the DSRC interface between OBE and RSE
including its functions to perform the fee collection. All the equipment used for enforcement (e.g. detection,
classification, localization, and registration) and central equipment are outside the scope of this document.

5 Test parameters and test procedures for EFC
5.1 Tests overview
5.1.1 General
The test parameters for EFC systems or components are categorized in three groups as follows:
a) referenced pre-tests;
b) functionality tests;
c) quality tests.
Figure 3 shows the general structure of all test parameter groups relevant for EFC systems and those which
are relevant to this document. The test parameters for pre-tests are taken from sources. The specific test
parameters that are ultimately deemed relevant for a specific EFC system shall be identified and listed in
the test plan according to 5.3. The individual test plan for type approval or acceptance testing shall consider
those pre-tests that have already been passed, i.e. for EMC, DSRC, and environment.

ISO/DIS 14907-1:2025(en)
Figure 3 — Test plan — Interdependencies
5.1.2 Referenced pre-tests
The third category of tests is related to test parameters which are fundamental for the performance of
EFC equipment. The specific parameters and requirements are not within the scope of this document. The
parameters that are relevant can be assigned to the following groups:
— DSRC;
— EMC;
— environment.
5.1.3 Functionality tests
The first category of tests is related to test procedures which aim to verify the functionality of the EFC
equipment.
The functionality tests are related to the essential test parameters that need to be applied to verify the
performance and capability of EFC equipment of different vendors and system operators.

ISO/DIS 14907-1:2025(en)
The following parameters shall be tested:
— communication;
— EFC application;
— influence of vehicle characteristics;
— influence of traffic characteristics;
— environmental influences.
Communication and EFC application tests are described in 6.1. Tests related to vehicle and traffic
characteristics and environmental influences are listed in Annex B.
5.1.4 Quality tests
The second category of tests is related to procedures that aim to determine the quality of the EFC equipment.
These are relevant for both operators and users.
The following test parameters shall be tested:
— quality management;
— reliability;
— availability.
For some of these test parameters, there are some existing test procedures available, which are referenced.
These tests are described in 6.2 and Annex C.
5.2 Parameter overview
Tables 1 to 3 provide a comprehensive list of the parameters that are relevant for type approval or
acceptance testing of a complete EFC system, as well as components of an EFC system. The tables are divided
according to the subjects of 5.1.2, 5.1.3, and 5.1.4, namely referenced pre-tests, functionality, and quality.
The subclause in which the tests are described or referenced is shown. An indication as to the nature of
these tests (basic or conditional) is provided as not all tests are relevant to all operators and their specific
operating situations and environment.
As used in Tables 1 to 3,
— “basic” means that the identified tests are highly recommended as part of a foundation for meaningful
evaluation, and
— “conditional” means that the test shall be performed if, and only if, it is applicable to a feature identified
in the specification of the system or component under evaluation, for example, performing the lane
changing test (T6) if the RSE is characterized as multilane.
Table 1 provides a list of parameters that are necessary for pre-tests and whose performance and
conformance are tested by reference to existing standards or Technical Specifications.
Table 2 provides an overview of the parameters for which tests are defined in this document to measure the
performance and assess the level of conformance of an EFC system or components under test.
Table 3 provides a list of the quality tests.
NOTE The tests have been categorized into inspection tests, laboratory tests, simulation tests, and field tests. The
appropriate test or types of tests are indicated, in the following tables, for each parameter. It is not expected that all the
named types of tests for a parameter will be performed on that parameter. Where a set of appropriate tools is available
to a test house, it is up to the test house to decide which type of test is most appropriate to meet its specific remit.

ISO/DIS 14907-1:2025(en)
Where a particular category of test shall be performed to conform to this document, the test is indicated in
the following tables with a “p”. Where a particular category of test is optional, this is indicated with an “o”.

5.3 Test plan
The manufacturer or the test house carrying out the type approval or acceptance testing shall devise an
individual test plan for each tested EFC system or EFC component, in accordance with Figure 3, considering
the system-specific characteristics of the EFC application. With respect to type approval, the requirements of
applicable standards or other normative and referenced documents shall be tested by the manufacturer or
by a test house.
With respect to acceptance tests, only the features that are specified or implicit in the system specification
shall be tested. Where additional features are provided for contingent use at some future date, these shall be
tested only if such contingency is included in the system specification. Where additional features are present
in products supplied but are neither used nor included in the system specification or implementation, there
is no requirement that they shall be tested unless they affect the operation of the system.
Results of pre-tests that have already been passed shall be compared with the application-specific
requirements. If deviations are detected, additional tests will need to be carried out. The test plan shall
make references to each listed test parameter with respect to the following details:
— identification of test parameter and item;
— reference of the related requirements/severity of the test;
— required equipment and documentation;
— selected test type;
— required test equipment, measurement equipment, interfaces, and tools;
— required test environment;
— department carrying out the test;
— required documentation of the tests and the results (see G.5).
Interdependencies between the results of the different tests are anticipated and shall be considered by the
manufacturer or the test house. An example test protocol form is given in G.5.
5.4 Required documentation
The following listed documentation shall be supplied by the manufacturer to conduct the tests defined by a
test plan:
— system description (overview, block diagrams);
— system specification including functions, timing, operational data on a detailed level;
— safety and security concept (threat analysis, implemented measures to detect and control failures,
threats, and manipulations);
— user documentation (service provider and user);
— specification of ambient conditions;
— operational directives;
— quality assurance directives, development rules;
— maintenance and installation directives;
— list of all available documents from the manufacturer relating to the EFC system under test created
during the design and manufacture of the equipment.

6.2 Functionality tests
6.2.1 Communication
The test specifications regarding communication are defined in ISO 14907-2. It specifies the tests that verify
on-board unit (OBU) conformance of implemented communication (transaction) protocols to conform with
the specifications given in ISO 14906 to be used for EFC applications.
NOTE ISO 14907-2 can also be used as a source of inspiration for roadside equipment testing in accordance with
ISO 14906.
ISO/DIS 14907-1:2025(en)
ISO 14907-2 describes general requirements for conformance testing and specific test procedures for the
following:
— basic DSRC L7 functionality;
— EFC application functions;
— EFC attributes;
— addressing procedures of EFC attributes and (hardware) components, e.g. ICC and man-machine
interface (MMI);
— EFC transaction model;
— behaviour of the interface.
6.2.2 EFC application
6.2.2.1 General
The tests are related to components or to a complete EFC system consisting of an OBE, RSE, or both and
RSE/OBE in combination. The objective of the tests is to validate that the equipment to be tested fulfils the
functional and technical requirements of the specification. The proof consists of inspections, simulations, and
tests which are to ensure that the system specifications and the equipment of EFC are in conformance with
the EFC requirements based on standards and regulations, national requirements, and other requirements.
6.1.2.2 and 6.1.2.3 describe a set of tests (see also Annex B); which of those tests are relevant and sufficient
to prove the performance of an EFC system or its components shall be defined by a test plan (see 5.3).
The EFC application test is divided into two sections:
a) validation of the EFC specification;
b) inspection and test of the EFC system under test (SUT) or component under test.
The relationship between the test sections is shown in Figure 4.

6.1.2.2 addresses the validation of the EFC system specification with respect to the design specification.
The objective is a validation of the system specification to verify that it is in conformance with the EFC
requirements based on standards and regulations, national requirements, and other requirements. The
activity consists of inspection and analysis of the referenced documentation. The output of this phase is
an authorized and valid system specification of the SUT which meets the requirements of the selected
standards and regulations. Additionally, a test plan will be specified which identifies the required test steps
to prove the performance of the SUT.
6.1.2.3 addresses EFC equipment that is designed according to a validated system specification. The
activities of this section are inspections, simulations, and tests. Before the functionality test can start, an
implementation test (pre-test after installation) is carried out to ensure the principal performance of the
system. The implementation includes the activities of installation and commissioning. The objective of the
tests is to validate the conformity of the equipment with the specification and compliance with the EFC
requirements of standards and regulations, national requirements, and other requirements.

ISO/DIS 14907-1:2025(en)
The inspection and test shall take into consideration results of tests that have been previously performed,
e.g. quality tests and reference tests, and shall be detailed by a test plan (see 5.3). Annex B contains a list
of tests that are related to traffic conditions, vehicle characteristics, and other environment influences.
Annex H provides examples of EFC scenarios as part of a functionality test.
