AS ISO 6746.1-2021 pdf free download.Earth-moving machinery – Definitions of dimensions and codes Part 1: Base machine.
This part of ISO 6746 defines certain dimensions of earth-moving base-machines as well as the codes identifying those dimensions. At the same time, it specifies a reference system for defining, and a coding system for identifying, additional, similar dimensions in terminology standards and commercial specifications.
It is applicable to the basic types of earth-moving machinery as defined in Iso 6165.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (Including any amendments) applies.

3 Terms and definitions
For the purposes of this part of ISO 6746, the terms and definitions given in ISO 6165 and the following apply.
3.1 three-dimensional reference system
system used to determine dimensions of earth-moving machines
SEE:
3.1.1 zero Y plane
vertical plane which passes through the longitudinal centreline of the machine
3.1.2 Xplane
any vertical plane perpendicular to the Y plane
3.1.3 Z plane
any horizontal plane perpendicular to the X and Y planes
3.1.4 positive coordinate
positive direction, forward from the zero X plane, right from the zero Y plane and above the zero Z plane
Note 1 to entry: The intersection of the X, Y, Z axes (zero planes) is normally located at a well-defined base point:
i.e. SIP for a seat as defined in ISO 5353; crankshaft centreline for an engine; sprocket or rear axle centreline for a tractor-dozer; ground line for machine measurements.
Note 2 to entry: If only components (e.g. engine, seat) are shown, the location and positive direction of the axis from the intersection of the X, Y, Z axes (zero planes) assume the normally expected orientation of the component to a machine, i.e. number one cylinder of engine to the front of the machine, seat facing to the front.
Note 3 to entry: lithe machine or its equipment or attachment or all these are illustrated, a machine driving from right to left is shown.AS ISO 6746.1 pdf download.
