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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Introduction
This set of standards includes the requirements to be fulfilled by Repair and Maintenance Information
(RMI) systems as applied by the European Commission — Enterprise and Industry Directorate-General,
[[5]]
Consumer goods — Automotive industry EC mandate M/421, dated Brussels, 21 January 2008.
This mandate relates to the EC type-approval system for vehicles falling into the scopes of Directives
[8] [6] [7]
70/156/EEC (replaced by 2007/46/EC ), 2002/24/EC and 2003/37/EC and, in particular, to
requirements for access to vehicle repair and maintenance information by independent operators.
This International Standard only covers access to automotive repair and maintenance information for
light passenger and commercial vehicles (see NOTE 1) and heavy duty vehicles (see NOTE 2) based on
[8]
Directive 70/156/EEC (replaced by 2007/46/EC ).
The purpose of the EC Mandate M/421 is to develop a standard or set of standards which specify the
requirements to provide standardized access to automotive repair and maintenance information (RMI)
for independent operators.
The information included in this part of ISO 18541 derives from the legislative requirements on European
level in the field of RMI and related security requirements and can be referenced by legislation in other
countries.

Part 2:
Technical requirements
1 Scope
This part of ISO 18541 includes technical requirements which are related to automotive repair and
maintenance information (RMI) systems in order to standardize access to RMI for independent operators.
This part of ISO 18541 specifies the minimum set of technical requirements related to a vehicle
manufacturer’s RMI system. These requirements will reflect the deriving needs from the use cases as
specified in ISO 18541-1.

4 Conventions
This part of ISO 18541 is based on the conventions discussed in the OSI Service Conventions
(ISO/IEC 10731).
5 Requirements overview and principles
5.1 Basic principles for requirements definition
Basic principles have been established as a guideline to define the requirements.
— BP1: The requirements stated in this part of ISO 18541 shall not specify any implementation details.
— BP2: Requirements shall be expressed in terms of performance rather than design or descriptive
characteristics. This approach leaves maximum freedom to technical development.
— BP3: A requirement is identified by a TREQ-xx, where ‘xx’ is the requirement number. Each
requirement consists of a “Main title”, “Requirement definition”, “Requirement description”,
“Explanatory / Example” and “Classification”.
— BP4: The requirements in clusters 4 and 5 in this part of ISO 18541 have been formulated with the
aim of minimizing the number of IO clients (PC, Laptop, etc.) required to access different VM RMI
systems.
5.2 Requirements clustering
Figure 1 illustrates the technical requirements clusters. Figure 1 shall provide an overview about all
technical requirements clusters and the specific technical requirements. Each technical requirement
is identified by the mnemonic “TREQ-” and an alpha-numeric number. The name of the technical
requirement is descriptive for the area.
