It is identical with ISO8759-1:1985 “Agricultural wheeled tractors Front-mounted linkage and power take-
8、off Part1: Power take-off” prepared by Technical Committee ISO/TC23, Tractors and machinery for agriculture and forestry, of the International Organization for Standardization (ISO). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as
9、a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. Wherever the words “part of ISO8759” appear, referring to this standard, they should be read as “Part of BS6818”. The
10、 Technical Committee has reviewed the provisions of ISO4254-1 and ISO730-1, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard for ISO730-1 is BS1841 “Attachment of mounted implements to agricultural
11、wheeled tractors” Part2 “Metric units”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. C
