2、tional Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has be
3、en established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical stan
4、dardization. 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. International Standard IS0 6747 was prepared by Technical Co
5、mmittee lSO/TC 127, Earth-moving machinery, Subcommittee SC 4, Commercial nomenclature, classification and rating. This third edition cancels and replaces the second edition (IS0 6747:1988), of which it constitutes a technical revision. Annex A forms an integral part of this International Standard.
