This International Standard provides a basis for content and methods used for operator training for earth-moving machinery as defined in ISO 6165. The training in turn provides the basis for developing operators of earth-moving machinery who are knowledgeable and understand the manufacturer's instructions for safe and proper operation and routine maintenance. It establishes criteria for evaluating the competency of a person who operates and could perform routine maintenance of earth-moving machinery, but does not specify any procedure for proficiency testing or assessment of the operator's competence of operating and maintaining earth-moving machinery. It is not intended to substitute for national or regional requirements or regulations related to operator training.
