12、ional foreword This British Standard has been prepared under the direction of the Mechanical Engineering Standards Committee. It is identical with ISO2924 “Solid and segmental circular saws for cold cutting of metals Interchangeability dimensions of the drive Saw diameter range224 to2240mm” and is a

13、 revision of BS387:1948. Terminology and conventions. The text of the International Standard has been approved as suitable for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especial

14、ly drawn to the following. Where the words “International Standard” appear, referring to this standard, they should be interpreted as “British Standard”. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the dec

15、imal marker. The technical committee has reviewed the provisions of ISO/R240 1)and ISO/R523 1) , to which reference is made in clause3, and has decided that they are acceptable for use in conjunction with this standard. Compliance with a British Standard does not of itself confer immunity from legal

16、 obligations. 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.
