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).

This document was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This second edition cancels and replaces the first edition (ISO/TR 23605:2009), which has been
technically revised.
The main changes to the previous edition are as follows:
— a general update in line with the revised ISO GPS matrix, ISO 14638:2015;
— the category of ‘global’ standards has been removed, as per ISO 14638:2015, with standards now
categorized as ‘fundamental’ or ‘general’ ISO GPS standards;
— new, amended and/or revised standards have been added or updated throughout the document,
including in Annex A, which lists all cross-referenced standards;
— a new Annex B, ‘Withdrawn standards’, provides a list of all previously current ISO/TC 213 standards
referred to in this document.
Introduction
Industry in all developed countries worldwide is showing an increasing tendency to focus on design
and assembly activity and to contract out the manufacture of its components, and such procedures are
unlikely to be constrained by national borders. Alongside this, many companies are extending their
dependence on computerized systems and thereby reducing the opportunity for human intervention in
manufacturing processes.
One effect of these parallel trends is the exposure of the limitations of some traditional specification
processes, which highlights the urgent need for enhanced detail and accuracy in specifying the
manufacture of technical products. This is coupled with the requirement to reduce ambiguity and the
opportunity for interpretation at both manufacturing and verification stages.
This document is drafted with the sole objective of facilitating this improvement in technical product
specification (TPS) through the application of established International Standards and International
Standards under development.
A primary objective of the responsible ISO committees is to ensure that the necessary tools to
enable the preparation of detailed, accurate specifications are available. Their activity covers seven
complementary generic subject areas:
— methodology for design implementation;
— geometrical product specification;
— graphical representation (engineering drawings/diagrams and 3-D modelling);
— verification (metrology and precision measurement);
— technical documentation;
— electronic formats and controls;
— related tools and equipment.
There are two ISO Technical Committees responsible for identifying and evaluating requirements
for International Standards relating to the preparation, presentation and validation of technical
specifications in the field of mechanical engineering and for the drafting of any such standards for
which a genuine need is established. Their combined work programmes address the requirements for
standardization in such technical specifications at all stages from the preparation of design concepts
for physical realization to the validation of finished products.
Technical product documentation (TPD) is the province of ISO/TC 10, with the scope to develop, co-
ordinate and maintain International Standards for TPD, “including technical drawings, manually
produced or computer based for technical purposes throughout the product life cycle, to facilitate
preparation, management, storage, retrieval, reproduction, exchange and use”.
Although this committee is founded on the more traditional discipline of engineering drawing, its remit
extends to include the presentation of all forms of specification for technical products, whatever the
media selected to carry that specification. In particular, this includes the graphical representation and
annotation of the output of 3-D modelling programmes. The work of ISO/TC 10 is closely linked to that
of ISO/TC 213 (see below) and the closest practicable liaisons are maintained, both at the policy-making
level and between the working groups.
ISO/TC 213 is the Technical Committee responsible for the development of standards for geometrical
product specifications (GPS). Its primary objective is the development and promotion of an integrated
system for specification and verification of workpiece geometry that can function as an enhanced
engineering tool for product development and manufacturing. Such a system is essential as companies
move ahead rapidly with new technologies, new manufacturing processes, new materials and
technically advanced products, in the environment previously known as international outsourcing.

This document sets out the format and overall content of a specification for the preparation of all forms
of TPS. It is designed to facilitate the development of national standards for the definition, specification
and graphical representation of technical products and includes cross-references to a range of
International Standards (the core range) judged to be essential to the achievement of international
compatibility between such national standards (see Annex A and see Annex B for a list of withdrawn
ISO/TC 213 standards). This core range of cross-referenced standards incorporates those prepared not
only by ISO/TC 213 but also by other relevant ISO Technical committees, principally ISO/TC 10. It is
intended that this model be adopted, in its entirety, by national standards bodies as the basis for their
national standards in the field of mechanical engineering specification. Attention is drawn to the fact
that its structure provides for the addition of supplementary information by way of commentary and
recommendation where national requirements make such addition appropriate, provided that any such
additions are not in conflict with the published International Standards.
The relationship between the cross-referenced standards is formally structured within this document.
Additionally, an overview of the international standardization of geometrical product specification,
explaining the concept and providing a matrix of the relevant standards, can be found in ISO 14638.
Standards developed in the field of GPS form an interrelated standards structure providing fundamental
rules for geometrical specification (see Annex C).
In this document, the GPS standards are applied in conjunction with the presentational TPD standards
to construct a comprehensive system for TPS.
It is appropriate to apply TPS principles throughout the development of a product, i.e. in design,
manufacturing, metrology and verification, and it will be found that consistent application will lead to
reduced ambiguity and misunderstanding, which in turn will provide faster, more controlled “release-
to-market” times, with significantly fewer restarts and reduced requirement for corrective action.

underpin or influence the whole TPS process. This principle is adopted in this document, and the
following standards are identified as being fundamental or general standards for this purpose.
NOTE The category of ‘global’ ISO GPS standards has been removed from ISO 14638, the ISO GPS matrix
standard. ISO GPS standards which had previously been categorized as global ISO GPS standards are now
categorized as either fundamental or general ISO GPS standards.

4.2 Standard reference temperature
The standard reference temperature for TPS and verification is 20 °C (see ISO 1).
5 Expression of the concept
Before specifying a technical product, the broad requirement should be established, with particular
attention being paid to the functions that the product will be expected to fulfil. The conceptual design
intent can then be depicted in the form of a design layout, scheme or simplified computer-generated
model, although this will not normally be used in the detailed technical product document for
manufacturing purposes.
The importance of this stage cannot be over-emphasized. Clear understanding of the purpose
and function intended for the eventual product, knowledge of the requirements of the available
manufacturing methods and awareness of relevant verification procedures will help to ensure that the
degree of complexity of the specification is appropriate and adequate.
It is not the aim of this document to attempt to instruct or constrain the design process. It is, however,
of the greatest importance that the designer present the product of the design process, i.e. the TPD
set containing the TPS, in a manner that avoids ambiguity and any risk of misunderstanding or
misinterpretation. For this reason, it is imperative that the designer be familiar with the guidance
within this document and aware of the increased precision that its use can bring.
For these and many other reasons, management of the overall design process can be complex, and it is
strongly recommended that designers familiarize themselves with published standards in this field.
6 Types of documentation
6.1 General
The technical product document should, if practicable, be of a type listed in one of the following
standards and be prepared in accordance with any corresponding recommendations therein:
ISO 7573, Technical product documentation — Parts lists
ISO 10209, Technical product documentation — Vocabulary — Terms relating to technical drawings,
product definition and related documentation
ISO 16792, Technical product documentation — Digital product definition data practices
6.2 Commentary and recommendations
6.2.1 Combined drawing
For some TPS, it might be appropriate to display an assembly, item list and constituent details, drawn
separately, all on the same drawing (see ISO/TS 8062-2).
6.2.2 Document list (drawing list)
For some TPS, it may be appropriate to provide a list of all graphical representations and selected
specifications required to build a particular assembly, from which it derives its title and primary
identifier.
7 Relationship between design definition and interpretation
7.1 Targeting of a TPD
When producing a TPD for manufacturing purposes, there can be benefits in giving consideration to
how it will be interpreted:
— including more detail than is necessary for the manufacturing operation can increase the risk of
misinterpretation;
— including requirements which are beyond the capability of the manufacturing process will lead to
an increase in non-compliance.
7.2 Uncertainty of specification
However much care is invested in the preparation of a TPS, there will inevitably be areas of uncertainty,
both within the specification and between the specification and the verification processes. To ensure
that the uncertainty is minimized, the principles applied should conform to the following standards:
