Geometrical Product Specifications (GPS) - Dimensional and geometrical tolerances for moulded parts - Part 3: General dimensional and geometrical tolerances and machining allowances for castings (ISO 8062-3:2007)

ISO 8062-3:2007 specifies general dimensional and geometrical tolerances, as well as machining allowance grades, for castings as delivered to the purchaser in accordance with ISO 8062-2. It is applicable for the tolerancing of dimensions and geometry, and required machining allowance of castings in all cast metals and their alloys produced by various casting manufacturing processes.
ISO 8062-3:2007 applies to both general dimensional and general geometrical tolerances, unless otherwise specified.
The dimensional tolerances covered by ISO 8062-3:2007 are tolerances for linear dimensions.
The geometrical tolerances covered by ISO 8062-3:2007 are:
       tolerances for straightness,
       flatness,
       roundness,
       parallelism,
       perpendicularity,
       symmetry, and
       coaxiality.
ISO 8062-3:2007 can be used for the selection of tolerance values for individual indications.

ISO 8062-3:2007(E)
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.
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 8062-3 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This first edition of ISO 8062-3, together with ISO 8062-1 and ISO/TS 8062-2, cancels and replaces
ISO 8062:1994, of which it constitutes a technical revision.
ISO 8062 consists of the following parts, under the general title Geometrical product specifications (GPS) —
Dimensional and geometrical tolerances for moulded parts:
⎯ Part 1: Vocabulary
⎯ Part 3: General dimensional and geometrical tolerances and machining allowances for castings
Rules is to form the subject of a future Part 2 [Technical Specification].

ISO 8062-3:2007(E)
Introduction
This part of ISO 8062 is a geometrical product specification (GPS) standard and is to be regarded as a
complementary process-specific tolerance standard (see ISO/TR 14638). It influences chain link 2 of the chain
of standards on mouldings.
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 defines a system of tolerance grades and machining allowance grades for cast metals
and their alloys.
The specified system applies if the manufacturer provides a pattern or die equipment, or accepts responsibility
for proving it.
The tolerances specified for a casting may determine the casting method. It is therefore recommended, before
the design or the order is finalized, that the customer liaise with the foundry to discuss:
a) the proposed casting design and accuracy required;
b) machining requirements;
c) the method of casting;
d) the location of the parting surfaces and the necessary draft angles;
e) the number of castings to be manufactured;
f) the casting equipment involved;
g) the consequences of the wear-out of the equipment during its life cycle;
h) the datum system in accordance with ISO 5459;
i) the casting alloy;
j) any special requirements, e.g. individual dimensional and geometrical tolerances, fillet radii, tolerances
and individual machining allowances;
NOTE Because the dimensional and geometrical accuracy of a casting is related to production factors, tolerance
grades which can be achieved for various methods and metals are described in Annex A.
k) dimensional tolerances for long series and mass production, where development, adjustment
