AS ISO 9245:2021 Earth-moving machinery一Machine productivity一Vocabulary, symbols and units. AS ISO 9245 gives a vocabulary of terms, their definitions, symbols and units used in the determination and presentation of the productivity of earth-moving machinery as defined in ISO 6165, except for graders, rollers, compactors and pipelayers. It does not in itself specify any rules for the determination of productivity nor does it give details on the form in which the productivity of earth-moving machinery should be presented. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard.

Influences liable to reduce the productivity arising from the condition of the equipment, from the organization of the construction site and from the weather are not taken into consideration here. An operator of average ability is assumed.AS ISO 9245 pdf download.
