8、dentical with ISO7852:1983 “Earth-moving machinery Plough bolt heads Shapes and dimensions (excluding thread dimensions)”, published by the International Organization for Standardization (ISO). ISO7852 was produced as a result of international discussion in which the UK took an active part. Terminol
9、ogy and conventions. The text of the International Standard has been approved as suitable for publication as 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. The comm
10、a 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 the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. A British Standard does not purport to i
11、nclude 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. Cross-references International Standard Corresponding British Standard ISO6165:19
