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 InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC 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.

ISO26402 was prepared by Technical Committee ISO/TC23, Tractors and machinery for agriculture and forestry, Subcommittee SC 4, Tractors. ii blank BSISO26402:2008 Agricultural vehicles Steering systems for agricultural trailersInterfaceforarticulatedsteeringdeviceof semi- mounted trailers Scope 1 This International Standard specifies the dimensions and clearance zones at the interface between tractorand 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. 2 Normative references The following referenced documents are indispensable for the application of this document.
