Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

www.iso.org/iso/foreword.html.

This document was prepared by Technical Committee ISO/TC 10, Technical product documentation, in

collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/SS

F01, Technical drawings, in accordance with the Agreement on technical cooperation between ISO and

CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 10209:2012), which has been technically

revised.
The main changes are as follows:
— certain terms have been added, deleted or revised;
— Annex A (deprecated terms) has been deleted.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www.iso.org/members.html.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 10, Technical product documentation.

This second edition cancels and replaces the first edition (ISO 10209:2012), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— New and/or updated terms from new or revised ISO/TC 10 standards, published since the 2012

edition of ISO 10209, have been added to this version of the document.

— References to the Subcommittee or part of the ISO/TC 10 area in which standards were developed

have been added.

— Notes have been added to clarify where terms first appeared, i.e. information is given on the original

version of the ISO/TC 10 standard in which the term appeared before it was removed and included

in ISO 10209.

— Terms which originated in former parts of the ISO 10209 series (now withdrawn) are flagged as

“[SOURCE: ISO 10209]”.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

Technical product documentation — Vocabulary — Terms
relating to technical drawings, product definition and
related documentation
1 Scope

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.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
