Geometrical Product Specifications (GPS) - Dimensional and geometrical tolerances for moulded parts - Part 2: Rules (ISO/TS 8062-2:2013, Corrected version 2013-11-01)
This part of ISO 8062 gives the rules for geometrical dimensioning and tolerancing of final moulded parts and parts machined out of moulded parts. It also gives rules and conventions for the indications of these requirements in technical product documentation and specifies the proportions and dimensions of the graphical symbols to be used. This part of ISO 8062 provides symbols which may be used to identify the relative completeness of the moulded features and parts. These graphical symbols should not be confused with the graphical symbols for surface texture according to ISO 1302, which are notably larger.

Dieser Teil von ISO 8062 gibt die Regeln zur geometrischen Bemaßung und Tolerierung für fertige Formteile
und aus Formteilen gefertigte Teile an. Es werden Regeln und Konventionen zur Angabe dieser
Anforderungen in der Technischen Produktdokumentation angegeben, und es werden Größenverhältnisse
sowie Maße der zu verwendenden graphischen Symbole festgelegt.
In diesem Teil von ISO 8062 werden Symbole angegeben, die zur Identifizierung der relativen Vollständigkeit
der geformten Elemente und Formteile angewendet werden können. Diese graphischen Symbole sollten nicht
mit den graphischen Symbolen für die Oberflächenbeschaffenheit nach ISO 1302 verwechselt werden, die
bedeutend größer sind.

ISO/TS 8062-2:2013(E)
Introduction
This part of ISO 8062 is to be regarded as a complementary process-specific tolerance geometrical
production specification (GPS) standard (see ISO/TR 14638). It influences chain links 1, 2 and 3 of the
chain of standards on mouldings.
The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this
document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and
the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this
document, unless otherwise indicated.
For more detailed information about the relation of this part of ISO 8062 to other standards and the GPS
matrix model, see Annex F.
This part of ISO 8062 takes into account experiences with the application of previous standards
(e.g. ISO 8062:1994, ASME Y14-8M:1996, and ISO 1101).
The tolerancing methods in this part of ISO 8062 are not yet fully developed within the new approach of
geometrical product specifications (GPS) according to ISO 17450. The requirements for castings (mainly
due to the uncertainty in the calculation of the shrinking of the casting) remain incompatible with
the GPS standards. Therefore, this Technical Specification has been issued in order to gather further
experience in the tolerancing of castings.
It is intended that the next version of this document will include more realistic ways of calculating the
nominal dimension d of the final moulded part by elaborating GPS-conformant ways of combining
C
linear dimensions and tolerance zones.
This document is intended to cover all types of moulded parts. However, most of the examples refer to
castings.
When the methods of this part of ISO 8062 are used in 3D models, provisions have to be made in order
to distinguish between theoretically exact dimensions (TEDs) and linear and angular dimensions with
plus/minus tolerances.

Part 2:
Rules
1 Scope
This part of ISO 8062 gives the rules for geometrical dimensioning and tolerancing of final moulded
parts and parts machined out of moulded parts. It also gives rules and conventions for the indications of
these requirements in technical product documentation and specifies the proportions and dimensions
of the graphical symbols to be used.
This part of ISO 8062 provides symbols which may be used to identify the relative completeness of
the moulded features and parts. These graphical symbols should not be confused with the graphical
symbols for surface texture according to ISO 1302, which are notably larger.

6.1 Single and combined drawings
The requirements for the three types of moulded-part conditions (final moulded, intermediate and final
machined) can be specified on a combined drawing or separately on single drawings as appropriate.
If use of the symbology in this document makes a combined drawing difficult to read, use single
drawings instead.
Information, as to which part condition or conditions the stated specifications on the drawing apply,
shall be indicated on the drawing in accordance with the following clauses; therefore the drawing shall
indicate which part condition(s) the stated specification applies to.
On combined drawings, only the outline of the most advanced part condition for which the drawing is
valid shall be illustrated. Requirements for the most advanced condition and for the preceding moulded-
part condition in question shall be stated.
6.2 Final moulded part drawings
If the drawing specifies requirements on a final moulded part, the graphical symbol given in Figure 1
shall be indicated in or near the drawing title block.

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.

ISO/TS 8062-2:2013(E)
Introduction
This part of ISO 8062 is to be regarded as a complementary process-specific tolerance geometrical
production specification (GPS) standard (see ISO/TR 14638). It influences chain links 1, 2 and 3 of the
chain of standards on mouldings.
The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this
document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and
the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this
document, unless otherwise indicated.
For more detailed information about the relation of this part of ISO 8062 to other standards and the GPS
matrix model, see Annex F.
This part of ISO 8062 takes into account experiences with the application of previous standards
(e.g. ISO 8062:1994, ASME Y14-8M:1996, and ISO 1101).
The tolerancing methods in this part of ISO 8062 are not yet fully developed within the new approach of
geometrical product specifications (GPS) according to ISO 17450. The requirements for castings (mainly
due to the uncertainty in the calculation of the shrinking of the casting) remain incompatible with
the GPS standards. Therefore, this Technical Specification has been issued in order to gather further
experience in the tolerancing of castings.
It is intended that the next version of this document will include more realistic ways of calculating the
nominal dimension d of the final moulded part by elaborating GPS-conformant ways of combining
C
linear dimensions and tolerance zones.
This document is intended to cover all types of moulded parts. However, most of the examples refer to
castings.
When the methods of this part of ISO 8062 are used in 3D models, provisions have to be made in order
to distinguish between theoretically exact dimensions (TEDs) and linear and angular dimensions with
plus/minus tolerances.

Part 2:
Rules
1 Scope
This part of ISO 8062 gives the rules for geometrical dimensioning and tolerancing of final moulded
parts and parts machined out of moulded parts. It also gives rules and conventions for the indications of
these requirements in technical product documentation and specifies the proportions and dimensions
of the graphical symbols to be used.
This part of ISO 8062 provides symbols which may be used to identify the relative completeness of
the moulded features and parts. These graphical symbols should not be confused with the graphical
symbols for surface texture according to ISO 1302, which are notably larger.

5 Designation on drawings
When drawing indications according to this part of ISO 8062 apply, the drawing shall be designated in
or near the drawing title block:
ISO/TS 8062-2
However, this reference is not required if general tolerances or required machining allowances according
to other parts of ISO 8062 are referenced.
6 Drawing type indicator
6.1 Single and combined drawings
The requirements for the three types of moulded-part conditions (final moulded, intermediate and final
machined) can be specified on a combined drawing or separately on single drawings as appropriate.
If use of the symbology in this document makes a combined drawing difficult to read, use single
drawings instead.
Information, as to which part condition or conditions the stated specifications on the drawing apply,
shall be indicated on the drawing in accordance with the following clauses; therefore the drawing shall
indicate which part condition(s) the stated specification applies to.
On combined drawings, only the outline of the most advanced part condition for which the drawing is
valid shall be illustrated. Requirements for the most advanced condition and for the preceding moulded-
part condition in question shall be stated.
6.2 Final moulded part drawings
If the drawing specifies requirements on a final moulded part, the graphical symbol given in Figure 1
shall be indicated in or near the drawing title block.
