11、 (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 com
12、mittee 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 electrot
13、echnical 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 mem
14、ber 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 identify
15、ing any or all such patent rights. ISO 26322-1 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 4, Tractors. This first edition of ISO 26322-1 cancels and replaces ISO 4254-3:1992, of which it constitutes a technical revision. Additi
16、onal requirements have been included in order to take account of the technical evolution of the tractors and changes in their use that have occurred since publication of the replaced International Standard. ISO 26322 consists of the following parts, under the general title Tractors for agriculture a

18、fety requirements and their verification for the design and construction of standard tractors used in agriculture and forestry. These tractors have at least two axles for pneumatic-tyred wheels, with the smallest track gauge of the rear axle exceeding 1 150 mm, or tracks instead of wheels, with thei
19、r unballasted tractor mass being greater than 600 kg. NOTE Tractors having an unballasted mass not greater than 600 kg and a smallest adjustable track gauge of the axle bearing the larger tyres of u 1 150 mm are dealt with in ISO 26322-2. In addition, this part of ISO 26322 specifies the type of inf
20、ormation on safe working practices (including residual risks) to be provided by the manufacturer, as well as technical means for improving the degree of personal safety of the operator and others involved in a tractors normal operation, maintenance and use.

33、e of a person to a hazard resulting from the persons action during normal operation and service of the tractor 3.5 hazard machinery parts which can cause injury upon direct contact or by entanglement of personal apparel NOTE These parts include, but are not limited to, pinch points, nip points, and
34、projections on rotating parts. 4 Safety requirements 4.1 Fundamental principles, design guidance 4.1.1 The tractor shall be designed according to the principles of risk reduction specified in ISO 12100-1:2003, Clause 5, for hazards relevant but not significant. 4.1.2 Unless specified otherwise in th
35、is part of ISO 26322, safety distances shall be in accordance with ISO 13857:2008, Tables 1, 3, 4 and 6, and ISO 13854:1996, Table 1, as appropriate. 4.1.3 Tractor engine cover(s) that can be opened without tools may be considered an acceptable guard for rotating components provided that the engine
36、cover is removable from the tractor only by the use of tools. 4.2 Noise 4.2.1 Noise at the operators position Noise tests and measurements shall be made in accordance with ISO 5131. NOTE ISO 5131:1996, Annex A, gives procedures specific to agricultural and forestry tractors. 4.2.2 Noise emitted when
37、 in motion Noise tests and measurements shall be made in accordance with ISO 7216. 4.3 Controls 4.3.1 General 4.3.1.1 Controls such as steering wheels or steering levers, gear levers, control levers, cranks, pedals and switches shall be chosen, designed, constructed and arranged so that their locati
38、ons and methods of operation are in accordance with ISO 15077. 4.3.1.2 Hand-operated controls shall have minimum clearances in accordance with ISO 4252. This requirement does not apply to fingertip operation controls, such as push-buttons, electric switches. 4.3.2 Starting and stopping the engine 4.
39、3.2.1 A means shall be provided to enable prevention of inadvertent and/or unauthorized starting of the engine. Examples of such means include but are not limited to: an ignition or start switch with a removable key; a lockable cab; a lockable cover over the ignition or start switch; BS ISO 26322-1:
40、2008ISO 26322-1:2008(E) 4 ISO 2008 All rights reserved a security ignition or starting lock (e.g. key card activated); a lockable battery disconnect switch. 4.3.2.2 Tractors equipped with starter interlocks as per ISO 15077 on only the traction control clutch or combination traction clutch and brake
41、 control shall include means to prevent the operator from starting the tractor from the ground while, for example, holding the control(s) disengaged by hand. 4.3.2.3 It shall not be possible to start the engine with the PTO (power take-off) activated. A means shall be provided which prevents the PTO
42、 shaft from transmitting torque at engine start-up. EXAMPLE 1 An interlock switch which prevents engine cranking when the PTO control is in the run position. EXAMPLE 2 PTO clutch left disengaged until engagement is commanded after engine start. 4.3.2.4 Starting the engine shall not move the three-po
43、int linkage. 4.3.3 External control(s) for three-point linkage 4.3.3.1 External controls for either the front or rear three-point linkage shall operate under either one or the other of the following limitations: movement of the linkage, as measured at the lower hitch points, shall be limited to a ma
44、ximum of 100 mm for each activation of the control; movement of the linkage shall occur only while the control is held in the activation position. 4.3.3.2 External controls shall be located such that the operator can activate them while standing on the ground outside of the hazard zone between the t
45、ractor and the implement. This does not apply to external control system measures that eliminate or minimize the risks. For example, a control may be achieved by limiting the maximum rate of travel of the three-point hitch linkage. The preferred maximum height of the control(s) above the ground is 1
46、 800 mm, or 2 000 mm if technically justified. 4.3.3.3 Provision shall be made to prevent unintentional actuation of control(s). 4.3.3.4 Other arrangements are permitted provided they have an effect at least equivalent to the requirements set out in 4.3.3.1, 4.3.3.2 and 4.3.3.3. 4.3.4 PTO external c
47、ontrol(s) 4.3.4.1 The driver shall be able to operate the control(s) from a location which allows the operator to avoid contact with the PTO shaft or the IID (implement input device) and which also allows the operator to verify that no person is in a hazardous location between the tractor and attach
48、ed implement. The height of control(s) above the ground shall not exceed 2 000 mm. 4.3.4.2 Provision shall be made to prevent unintentional engagement of the PTO clutch. The control or controls shall be clearly identified and shall not be subject to confusion with other external control(s), if provi
49、ded (e.g. three-point linkage control or controls). 4.3.4.3 The start control shall work according to the “hold-to-run principle” for at least the first 3 s of actuation. 4.3.4.4 Engagement of the PTO using the external control(s) shall occur with no delay greater than that experienced when using the main PTO control.
