9、ds Committee. It is identical with ISO 6746-2:1987 “Earth-moving machinery Definitions of dimensions and symbols Part 2: Equipment”, published by the International Organization for Standardization (ISO). This Part of BS 6914 supersedes BS 6295-2:1982 which is withdrawn. ISO 6746-2 was produced as a
10、result of international discussion in which the UK took an active part. Terminology 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 use
11、d in British Standards; attention is drawn especially to the following. Wherever the words “part of ISO 6746” appear, referring to this standard, they should be read as “Part of BS 6914”. Reference is made in the text to ISO 7134:1985 for which no corresponding British Standard exists; this does not
12、 adversely affect the validity of the standard. 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 obliga
