It is identical with ISO 3823
11、 “Dental rotary instruments” Part 2:1986 “Steel and carbide finishing burs”, prepared by Technical Committee 106 “Dentistry” of the International Organization for Standardization (ISO). The titles of BS 6828-1 to BS 6828-9 are given in BS 6828-1. In 1991 the European Committee for Standardization (C
12、EN) accepted ISO 3823-2:1986 as European Standard EN 23823-2:1991. 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
13、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. Wherever the words “International Standard” and “part of ISO 3823” appear, referring
14、to this standard, they should be read as “British Standard” and “Part of BS 6828” respectively. 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
15、 not of itself confer immunity from legal obligations.
