This part of ISO 20474 gives the safety requirements specific to trenchers as defined in ISO 6165. It is
intended to be used in conjunction with ISO 20474-1, which specifies general safety requirements common to
earth-moving machine families, and with ISO/TS 20474-14, which gives information on provisions that are
mandatory in particular countries or regions. The specific requirements given in this part of ISO 20474 take
precedence over the general requirements of ISO 20474-1.
This part of ISO 20474 deals with all significant hazards, hazardous situations and events relevant to the
earth-moving machinery within its Scope when used as intended or under conditions of misuse reasonably
foreseeable by the manufacturer (see also ISO/TS 20474-14). It specifies the appropriate technical measures
for eliminating or reducing risks arising from significant hazards, hazardous situations or events during
commissioning, operation and maintenance. It is not applicable to machines manufactured before the date of
its publication.
