9、ions. 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 Standards; attention is drawn especially to the following. The comma has been used
10、 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 “part of ISO 8255” appear, referring to this standard, they should be read as “Section of BS 7011”. Additional information. Referring to clause 4 e), for mi
