6、verBS7006:1989 ii BSI 11-1999 National foreword This British Standard has been prepared under the direction of the Agricultural Machinery and Implements Standards Committee. It is identical with ISO8912:1986 “Equipment for working the soil Roller sections Coupling and section width”, published by th

7、e 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. Some terminology and certain conventions are not identical with those used in British Sta

8、ndards; attention is drawn especially to the following. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. The Technical Committee has reviewed the provisions of ISO4254-1, to which reference is made in the text, and has decided

9、 that they are acceptable for use in conjunction with this 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 immun
