The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6746-1 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 4, Commercial nomenclature, classification and rating.
This third edition cancels and replaces the second edition (150 6746-1:1987), which has been technically revised.
ISO 6746 consists of the following parts, under the general title Earth-moving machinery — Definitions of dimensions and codes:
— Part 1: Base machine
— Part 2: Equipment and attachments
A single capital letter shall be used to indicate the type of base-machine dimension, according to
the following:
H = height (see Annex A);
W= width (see Annex B);
L = length (see Annex C];
R = radius (see Annex D];
A = angle (see Annex E).
More than one reference number may be added to the appropriate capital letter, depending on the needs of the specific earth-moving base machine for which a standard or commercial specification is being developed.AS ISO 6746.1 pdf download.
