    14、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. I

    15、nternational 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

    16、 the rules given in the ISO/IEC Directives, Part 3. 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

    17、 the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

    19、 specifies a method for determining the payloads, vertical static drawbar loads and axle loads of agricultural semi-mounted and balanced trailers by means of weighing the empty trailer and then calculating the requirements. 2 Terms and definitions For the purposes of this International Standard, the

    20、 following terms and definitions apply. 2.1 semi-mounted trailer towed vehicle with one axle or axle group of landwheels and a drawbar towing device (drawbar) that cannot move relative to the vehicle, allowing the transmission of vertical forces from the towed vehicle through the drawbar to the towi

    21、ng vehicle NOTE 1 Some slight vertical movement may occur at a rigid drawbar (e.g. due to suspension movements). NOTE 2 A hydraulically adjustable articulated drawbar is considered to be a rigid drawbar. 2.2 balanced trailer towed vehicle with at least two landwheel axles at least one of which is st

    22、eerable, and a drawbar towing device that allows vertical movement so that vertical forces cannot be transferred to the towing vehicle 2.3 axle load that part of the mass of the trailer and any payload carried by a particular ground wheel axle of the trailer or, in the case of multiple axles, the co

    23、mbined axle load NOTE The maximum permissible axle load is specified by the manufacturer. 2.4 vertical static load vertical load resulting from the loads produced by the mass of a semi-mounted trailer exerted at the centre of the drawbar coupling point under static conditions NOTE The maximum permis

    24、sible vertical static load is specified by the manufacturer. 2.5 maximum mass technically maximum possible trailer mass and allowable payload specified by the manufacturer NOTE This mass corresponds to the sum of the technically maximum possible axle loads and, in the case of a semi-mounted trailer,
