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

9、 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 7007”. Cross-references. The Technical Committee has reviewed the provisions ofISO 554 and ISO 3017, to which refe
