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 26402 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and
forestry, Subcommittee SC 4, Tractors.

INTERNATIONAL STANDARD ISO 26402:2008(E)

Agricultural vehicles — Steering systems for agricultural
trailers — Interface for articulated steering device of semi-
mounted trailers
1 Scope
This International Standard specifies the dimensions and clearance zones at the interface between tractor and
trailer for articulated steering devices of semi-mounted trailers used in agriculture. It also specifies the
maximum permissible forces at the connection of such articulated steering devices.
It is applicable exclusively in conjunction with ISO 24347, specifying a ball-type (mechanical) coupling device
of 80 mm nominal diameter.
It is not applicable to the verification of the mechanical strength of the interface of the articulated steering
device's interface, nor to the mechanical coupling device; this International Standard does not include
technical requirements for the articulated steering device itself.
