8、7:1986 “Commercial vehicles and buses Cross-tooth gearbox flanges, type T”, published by the International Organization for Standardization (ISO). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation
9、. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Where
10、ver the words “International Standard” and “ISO 8667” appear, referring to this standard, they should be read as “British Standard” and “BS AU 214a-1” respectively. The Technical Committee has reviewed the provisions of ISO 1101:1983 to which reference is made in the text, and has decided that they
11、are acceptable for use in conjunction with this standard. A related British Standard to ISO 1101 is BS 308 “Engineering drawing practice” Part 3:1972 “Geometrical tolerancing”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are r
12、esponsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
