This document together with ISO 20770-1, deals with all significant hazards (see Annex C) for mobile drill rigs for in soil or soil and rock mixture in civil and geotechnical engineering, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine. The requirements of this part are complementary to the common requirements formulated in ISO 20770-1:____. This document does not repeat the common requirements from ISO 20770-1:____, but adds or replaces the requirements for application for mobile drill rigs.
