The other Parts of BS 7007 are as follows: Par
9、t 1: Specification for dimensions and designation of truncated cone abrasive products; Part 2: Specification for designation and dimensions of coated abrasive flap wheels with shafts. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as
10、 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. Wherever the words “International Standard” appear, referring to this standard, they should be read as “Part of BS 7
11、007”. Cross-references. The Technical Committee has reviewed the provisions of ISO 554 and ISO 3017, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. The references to ISO 1929 and ISO 2235 are included for information only.
12、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 obligations. Summary of pages This document comprises
