13、oreword 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 te
14、chnical 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
15、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
16、 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 f
17、or identifying any or all such patent rights. ISO 3463 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 2, Common tests. This fourth edition cancels and replaces the third edition (ISO 3463:1989), which has been technically revised.
18、It also incorporates the Amendment ISO 3463:1989/Amd 1:1998.

19、,- ISO 3463:2006(E) ISO 2006 All rights reserved v Introduction Testing of roll-over protective structures (ROPS) for wheeled tractors for agriculture and forestry aims at minimizing the likelihood of driver injury resulting from accidental overturning during normal operation (e.g. field work) of th
20、e tractor. The strength of the ROPS is tested by applying dynamic impact loads and a static crushing test to simulate actual loads which can be imposed on the cab or frame when the tractor overturns either to the rear or to the side without free fall. The tests allow observations to be made on the s
21、trength of the structure and the attachment brackets to the tractor, and also of the tractor parts that could be affected by the load imposed on the structure. Provision is made to cover both tractors with the conventional forward facing drivers position only, as well as those with a reversible driv
22、ers position, which is in agreement with the relevant OECD test code practice. For tractors with a reversible drivers position, a clearance zone is defined to be the combined clearance zones for the two driving positions. The point of application of the side loading is determined as the mid-point be
23、tween the seat index points measured in the two positions. It is recognized that there may be designs of tractors for example, lawn-mowers, narrow vineyard tractors, low profile tractors used in low buildings with limited overhead clearance, orchards, etc., stilt tractors and certain forestry machin
24、es such as forwarders for which this International Standard is not appropriate. NOTE For narrow-track wheeled tractors, see ISO 12003-15 and ISO 12003-26.

27、 and the acceptance conditions for roll-over protective structures (cab or frame) of wheeled tractors for agriculture and forestry. It is applicable to tractors having at least two axles for wheels mounted with pneumatic tyres, or having tracks instead of wheels, with an unballasted tractor mass of
28、not less than 600 kg, but generally less than 6 000 kg, and with a minimum track width of the rear wheels greater than 1 150 mm. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For
29、 undated references, the latest edition of the referenced document (including any amendments) applies.

31、zes the likelihood of driver injury resulting from accidental overturning during normal operation NOTE The ROPS is characterized by the provision of space for a clearance zone, either inside the envelope of the structure or within a space bounded by a series of straight lines from the outer edges of
32、 the structure to any part of the tractor that might come into contact with flat ground and that is capable of supporting the tractor in that position if the tractor overturns.

36、. 3.6 longitudinal median plane longitudinal plane of symmetry zero Y plane vertical plane Y passing through the mid-points of AB, perpendicular to AB, A and B being such that for each wheel, the vertical plane passing through its axis cuts the mid-plane of the wheel following a straight line which
37、meets the supporting surface of the vehicle at one point, and A and B are two points thus defined which correspond to two wheels, both of which are either steering or powered wheels, situated respectively at the two ends of the same real or imaginary axle See Figure 1. NOTE 1 The mid-plane of the du
38、al wheels being equidistant from the inner edge of one wheel and the outer edge of the other, the straight line is, in this particular case, the intersection of the mid-plane of the dual wheels and the vertical plane passing through the axis of the axle pin.
