The work of preparing International Standards is norma
12、lly 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in th
13、e work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters 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
14、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
15、of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 4254-5 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 3, Safety and comfort.

20、inery is as follows. a) Type-A standards (basis standards) give basic concepts, principles for design, and general aspects that can be applied to machinery. b) Type-B standards (generic safety standards) deal with one or more safety aspect(s) or one or more type(s) of safeguards that can be used acr
21、oss a wide range of machinery: type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise); type-B2 standards on safeguards (e.g. two-hands controls, interlocking devices, pressure sensitive devices, guards); c) Type-C standards (machinery safety standards) dea
22、l with detailed safety requirements for a particular machine or group of machines. This part of ISO 4254 is a type-C standard as stated in ISO 12100-1. When provisions of this type-C standard are different from those which are stated in type-A or type-B standards, the provisions of this type-C stand
23、ard take precedence over the provisions of the other standards for machines that have been designed and built according to the provisions of this type-C standard. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this p
24、art of ISO 4254. These hazards are specific to power-driven soil-working machines. Significant hazards that are common to all the agricultural machines (self-propelled, mounted, semi-mounted and trailed) are dealt with in ISO 4254-1.

27、ed together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted and trailed power-driven soil-working machines used in agriculture. In addition, it specifies the type of information on safe working practices (including re
28、sidual risks) to be provided by the manufacturer. This part of ISO 4254 deals with significant hazards (as listed in Annex A), hazardous situations and events relevant to power-driven soil-working machines used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This pa
29、rt of ISO 4254 is not applicable to: spading machines; machines fitted with a retractable device making them capable of working between two successive plants in the same row. This part of ISO 4254 is not applicable to environmental hazards or electromagnetic compatibility. It is not applicable to ha
30、zards related to moving parts for power transmission, except for strength requirements for guards and barriers, nor to maintenance or repairs carried out by professional service personnel. NOTE 1 Specific requirements related to road traffic regulations are not taken into account in this part of ISO
31、 4254. NOTE 2 Vibrations are not regarded as a significant hazard in the case of mounted, semi-mounted or trailed machines. This part of ISO 4254 is not applicable to power-driven soil-working machines which are manufactured before the date of its publication. When requirements of this part of ISO 4
32、254 are different from those which are stated in ISO 4254-1, the requirements of this part of ISO 4254 take precedence over the requirements of ISO 4254-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the

36、plant and crop residues or animal manure during tillage NOTE See Annex B for examples of such machines. 3.2 attachment equipment which can be fitted to a power-driven soil-working machine and which allows the function of the machine to be modified 3.2.1 attachment preventing access attachment which
37、restricts access onto the top of the power-driven soil-working machine and its driven tools at the rear EXAMPLE Seed drills. 3.2.2 attachment not preventing access equipment which allows access onto the top of the power-driven soil-working machine EXAMPLE Frames, rollers or harrows. 4 Safety require
38、ments and/or measures 4.1 General Machinery shall comply with the safety requirements and/or protective measures of this clause. Unless otherwise specified in this part of ISO 4254, the machine shall comply with the requirements of ISO 4254-1. The compliance with the safety requirements and/or measu
39、res shall be verified in accordance with Clause 5. 4.2 Noise reduction at the design stage The main noise sources when operating power-driven mounted, semi-mounted and trailed soil-working machines are the tractor, the engagement of tools with the soil neither of which is under the control of the ma
40、chine manufacturer and the gearbox of the machine. Appropriately designed gearwheels, drives and oil bath lubrication and cooling may be seen as measures for noise reduction at the design stage. 4.3 Protection against inadvertent contact with power-driven tools 4.3.1 Machines shall be designed or gu
41、arded in accordance with 4.3.1.1 to 4.3.1.5 in order to avoid inadvertent contact with the powered tools at the front, rear, sides and top of the machine during normal operation and service. 4.3.1.1 At the front, sides and rear of the accessible zone shown in Figure 1, a barrier shall extend from th
42、e outermost path of the tools to a distance, a, beyond the path of the tools as shown in Figure 2 a) and b). 4.3.1.2 On the top of the machine, the area between the barriers shall be guarded as follows. a) The area covering the tools up to the outermost points of their path shall be guarded by a sol
43、id guard.

44、he area between the barriers and the edge of the top guard shall be covered in such a way that it is not possible to gain access to the tools. This guarding may be achieved by a guard, any suitable part of the machine or a combination of both. 4.3.1.3 On the sides and rear of the machine, when in th
45、e working position, for the guard covering the parts of the tools above the ground, distance a may extend to less than 200 mm (see Figure 3). 4.3.1.4 At the rear of the machine when the guard is hinged, its lower edges shall be at a minimum distance, d, in any position, in accordance with the dimens
46、ions shown in Figure 4. 4.3.1.5 The top guard, barriers and those parts of the machine ensuring the guarding shall be able to withstand a vertical downward load of 1 200 N. In addition, the barriers shall be capable of withstanding the following horizontal loads: a) 600 N for machines with a horizon
47、tal axis intended to be used with a tractor where the maximum power is u 37 kW according to 6.1 h); b) 1 000 N for all other machines. 4.3.2 The guard at the rear may be moveable or removable in order to permit the fitting of attachments. Attachments that afford equivalent protection to that provide
48、d by the rear guard may be used in place of the guard, provided that the following provisions are met. a) Such parts or such attachments shall not be power driven. b) Access to the driven tools shall be prevented by a barrier at any point on line ZY as shown in Figure 2 c). The area between the barrier and the top of the machine shall be covered in accordance with 4.3.1.2 b). c) When attachments preventing access (see 3.2.1) ar
