AS ISO 6746.1:2021 pdf download.Earth-moving machinery - Definitions of dimensions and codes Part 1: Base machine.

3.2

ground reference plane

GRP

plane on which the machine is placed for measurements: in the case of the base machine, a hard, level surface; in the case of

equipment and attachments, either a hard, level surface or compacted earth

Note Ito entry: The surface used depends on the intended use of the machine and its equipment and attachments. This needs to be

defined when developing specific ISO terminology standards or commercial specifications.

3.3

base machine

machine with a cab or canopy and operator-protective structures if required, without equipment or attachments but possessing the

necessary mountings for such equipment and attachments

4 General

Dimensions and codes for base machines are given in Annexes A to E, illustrating the use of the threedimensional reference system (see Figure 1) and the coding system specified in Clause 5 to define such dimensions and assign codes to them. Definitions of

dimensions and codes for equipment and attachments are given in ISO 6746-2.
