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.
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 13044-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 15,
Interchangeability of components of commercial vehicles and buses.
ISO 13044 consists of the following parts, under the general title Road vehicles — 24 V fully automatic coupling
systems (FACS) for heavy commercial vehicle combinations:
— Part 1: General requirements and definitions
— Part 2: Electrical and pneumatic interface for 50 mm fifth wheel couplings

Introduction
This part of ISO 13044 specifies general requirements and definitions to ensure the safe operation of fully
automated coupling systems (FACS).
The introduction of FACS has brought new perspectives and needs into the area of trailer couplings. This
has made evident the need for a resilient structure among trailer coupling classes. The ISO 13044 series is
intended to facilitate interaction between International Standards and relevant regulations.
The drivers for the introduction of FACS are the following:
— personnel injury hazards associated with coupling and uncoupling operations;
— system availability and operating cost;
— convenience.
It is foreseen that interfaces for media other than those included in this part of ISO 13044 will be entering
the area of trailer coupling in the future. Examples of those other media are hydraulic and radio frequency
transmissions. Definitions and general requirements for those interfaces will be included in later editions of this
part of ISO 13044.

INTERNATIONAL STANDARD ISO 13044-1:2012(E)
Road vehicles — 24 V fully automatic coupling systems (FACS)
for heavy commercial vehicle combinations —
Part 1:
General requirements and definitions
1 Scope
This part of ISO 13044 defines coupling classes, different levels of automation and the general limitations in
terms of topology and procedures with respect to electrical and pneumatic connections. This part of ISO 13044
provides a framework under which detailed connector designs applicable for fifth wheel or drawbar couplings
may be standardized. The framework refers to vehicle combinations that include trailers with a technical
maximum mass in excess of 3 500 kg.
