This document 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 document. 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. NOTE 2 In addition to terms and definitions used in English and French, two of the three official ISO languages, this document gives the equivalent terms in German; these are published under the responsibility of the member body for Germany (DIN), and are given for information only. Only the terms and definitions given in the official languages can be considered ISO terms and definitions.
