Each member body interested in a subject for which a technical committee has and non-governmental, in liaison with IsO, also take part in the work. IsO collaborates closely with the 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. ISO/OECD 789-10 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture Cooperation and Development (OECD). This first edition of ISO/OECD 789-10 cancels and replaces ISO 789-10:1996, which has been technically revised.
