7、on for Standardization (ISO). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a BritishStandard without deviation. Some terminology and certain conventions are not identical with those used in BritishStandards; attention is drawn e

8、specially to the following. The comma has been used as a decimal marker. In BritishStandards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be read as “BritishStandard”. The

9、 Technical Committee has reviewed the provisions of ISO1101:1983 to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related BritishStandard to ISO1101 is BS308 “Engineering drawing practice” Part3:1972 “Geometrical tolerancin
