NF EN ISO 4254-1

<p>ISO 4254-1:2008 specifies the general safety requirements and their verification for the design and construction of self-propelled ride-on machines and mounted, semi-mounted or trailed machines used in agriculture. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. </p> <p>ISO 4254-1:2008 deals with significant hazards (as listed in Annex A), hazardous situations and events relevant to this agricultural machinery used as intended and under the conditions foreseen by the manufacturer (see Clause 4).</p> <p>ISO 4254-1:2008 is not applicable to tractors, aircraft, air-cushion vehicles, or lawn and garden equipment.</p> <p>ISO 4254-1:2008 is not applicable to environmental hazards, road safety, electromagnetic compatibility, or to the power take-off (PTO) drive shaft; neither is it applicable to moving parts for power transmission except for strength requirements for guards and barriers (see 4.7), nor to vibration except in respect of declarations. It is not applicable to hazards related to maintenance or repairs to be carried out by professional service personnel.</p> <p>ISO 4254-1:2008 is not applicable to machines which are manufactured before the date of its publication.</p> <p>All of the hazards dealt with by ISO 4254-1:2008 will not necessarily be present on a particular machine. For any machine covered by ISO 4254-1:2008, the provisions of the part of ISO 4254 directly applicable to that type of machine, if available, take precedence over the provisions of ISO 4254-1:2008.</p>

<p>ISO 4254-1:2013 specifies the safety requirements and the means of their verification for the design and construction of self-propelled ride-on machines, mounted, semi-mounted and trailed machines used in agriculture in order to deal with the hazards which are typical for most of the machines. In addition, it specifies the type of information on safe working practices including information about residual risks to be provided by the manufacturer.</p> <p>This document deals with significant hazards, hazardous situations and events relevant to this agricultural machinery when used as intended and under the conditions of misuse foreseeable by the manufacturer during normal operation and service.</p> <p>ISO 4254-1:2013 is not applicable to</p> <ul> <li>? agricultural or forestry tractors,</li> <li>? aircraft and air-cushion vehicles used in agriculture,</li> <li>? lawn and garden equipment,</li> <li>? machine-specific components or functions (e.g. working tools and/or processes).</li> </ul> <p>ISO 4254-1:2013 is not applicable to hazards related to periodic service, machine conversion and repairs intended to be carried out by professional service personnel, environmental hazards, road safety (e.g. steering, braking), or to the power take-off (PTO) drive shaft; neither is it applicable to guards of moving parts for power transmission except for strength requirements for guards and barriers.</p> <p>ISO 4254-1:2013 is not applicable to machines which are manufactured before the date of its publication.</p> <p>Not all of the hazards dealt with by ISO 4254-1:2013 are necessarily present on a particular machine. A risk assessment should be carried out by the manufacturer to determine the hazards that are applicable and any hazards in addition to those dealt with by this part or a relevant machine-specific part. The requirements of a machine-specific part of ISO 4254 take precedence over the requirements of this part.</p>
