Description / Abstract:
This part of ISO 4254 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.
This document deals with significant hazards, hazardous
situations and events, as listed in Annex A, relevant to
this agricultural machinery when used as intended and under the
conditions of misuse foreseeable by the manufacturer during normal
operation and service.
This part of ISO 4254 is not applicable to
-agricultural or forestry tractors,
-aircraft and air-cushion vehicles used in
agriculture,
-lawn and garden equipment,
— machine-specific components or functions (e.g. working tools
and/or processes).
This part of ISO 4254 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.
This part of ISO 4254 is not applicable to machines which are
manufactured before the date of its publication.
Not all of the hazards dealt with by this part of ISO 4254 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.
