Technical product documentation — Digital product definition data practices
ISO 16792:2015 specifies requirements for the preparation, revision, and presentation of digital product definition data, hereafter referred to as data sets. It supports two methods of application: model-only and model and drawing in digital format. Its structure presents requirements common to both methods followed by clauses providing for any essential, differing requirements for each method. Additionally, its use in conjunction with computer-aided design (CAD) systems could assist in the progression towards improved modelling and annotation practices for CAD and engineering disciplines, as well as serving as a guideline for IT engineers. The aspects specified in this International Standard refer mainly, but not exclusively, to requirements that differ or are additional to those provided in existing, related standards. Where no such requirements are identified, it is safe to assume that the appropriate existing ISO standards are instead applicable.

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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 10, Technical product documentation.
This second edition cancels and replaces the first edition (ISO 16792:2006), which has been technically
revised mainly to incorporate the technical changes in ISO 1101:2012 and ISO 5459:2011. Clause
12 on indication for welds and Clause 13 on indications for surface texture have been added. A new
informative annex on classification codes has also been added.

ISO 16792:2015(E)
Introduction
Every effort was made during the preparation of the first edition of this International Standard,
adapted from ASME Y14.41:2012, to apply existing requirements developed for two-dimensional (2D)
presentation equally to the output from three-dimensional (3D) models. Where new geometrical
product specification (GPS) rules have proved essential, these have been drafted with a view to their
being equally applicable to both 2D and 3D. Therefore, in order to maintain the integrity of a single
system, these new rules are being incorporated in the relevant existing ISO standards for cross-
reference. Application examples have been included where, due to the specific requirements of 3D
modelling, additional guidance was deemed beneficial.
It is recognized that there is a need to support drawings in conjunction with 3D models now and for the
foreseeable future. This need has been addressed in this International Standard through the definition
of the two methods for documenting digital models and specification of requirements to ensure that
the information in a data set is consistent between the model and the drawing.
The figures in this International Standard are intended only as illustrations to aid the user in
understanding the practices elaborated in the text. In some cases, figures show a level of detail as
needed for emphasis; in others, they are only complete enough to illustrate a concept or facet thereof.
The absence of figures has no bearing on the applicability of the specified requirement or practice.
In order to comply with the requirements of this International Standard, actual data sets shall meet the
content requirements set forth in its text.
Most figures are illustrations of models in a 3D environment. Figures illustrating drawings in digital
format include a border.
Text in uppercase letters used in the figures are intended to appear in digital product definition data, or
data sets, while that in lowercase letters is for information only and is not intended to appear in data sets.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 16792 was prepared by Technical Committee ISO/TC 10, Technical product documentation.
This second edition cancels and replaces the first edition (ISO 167925:2006), which has been technically
revised mainly to incorporate the technical changes in ISO 1101:2012 and ISO 5459:2011. Clause 12 on
