9、ation) 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
10、 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 Standar
11、ds are drafted in accordance with 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 cast
12、ing a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 6489 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 6489-1 was prepared by Technical Committee ISO/TC 23,

17、ensional requirements for hitch-hooks used in the attachment to agricultural towing vehicles of towed, non-balanced trailers and implements equipped with a ring specified in ISO 20019. Its purpose is to ensure the interchangeability of the mechanical connections on agricultural towing vehicles. This
18、 part of ISO 6489-1 is applicable only in those cases where the vertical static load does not exceed 30 kN. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 6489. For dated references, subseque
19、nt amendments to, or revisions of, any of these publications do not apply.

21、 Dimensions for hitch rings. 3Dimensions 3.1General The location of the keeper and the dimensions of the hitch-hook shall be in accordance with Figures 1 to 3. The keeper shall be contained within the maximum metal outline. No part of the hitch-hook shall lie outside the radius marked R 67 max. betw
22、een points X and Y (maximum metal condition) in Figure 1. The manufacturer shall be responsible for both the design and manufacturing quality of the hitch-hook assembly. In order to prevent unintentional uncoupling from the hitch ring at the maximum design load, the distance between the hitch-hook t
23、ip and the keeper shall not exceed 10 mm. 1)To be published. (Revision of ISO 500:1991) 2)To be published.
