This International Standard establishes and defines terms used in technical product documentation relating to technical drawings, product definition and related documentation in all fields of application. This vocabulary is based on all terms contained within ISO/TC 10 standards and other documents that are relevant to technical product documentation irrespective of disciplines. The terms have been classified into specific fields of application. New terms required by ISO/TC 10 Subcommittees and Working Groups for new or revised standards will be ratified by the ISO/TC 10 vocabulary maintenance team and included in future amendments of this International Standard. NOTE 1 Annex A contains a list of terms and definitions which previously appeared in former parts of ISO 10209 and for which there are now new definitions in current ISO/TC 10 standards.
