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 213, Dimensional and geometrical product
specifications and verification.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Replace the first sentence by the following:
For the purposes of this document, the terms and definitions given in ISO 1101, ISO 2692, ISO 17450-1,
ISO 17450-2 and the following apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

Delete definitions 3.14, 3.16, 3.22 and renumber the definitions.
Add at the end of Clause 3 the following new terms and definitions.
3.20
datum coordinate system
coordinate system established from a datum system
Note 1 to entry: The datum coordinate system can be used to describe the degrees of freedoms which are locked
by the datum system.
ISO 5459:2011/DAM 1:2022(E)
Note 2 to entry: Using a datum coordinate system is optional.
3.20.1

label identifying a coordinate system
3 Clause 4
Replace the first row of Table 1 by the following.
Datum feature indicator 7.2.1
Add the following new rows to Table 1 after the row "Moveable datum target frame".
Single datum target indica-
7.4.2.1

Table H.1.
ISO 5459:2011/DAM 1:2022(E)
4 Subclause 6.1
Replace the NOTE by the following.
NOTE Datums and datum systems are situation features, not coordinate systems. A complete datum system
(allowing to lock all degrees of freedom) is a set of a point, a line and a plane (the point on the line in the plane).
Coordinate systems can be built on datums, see Annex G.
5 Subclause 6.2.1
Replace the whole 6.2.1 by the following.
The recommended status (variable or fixed) of the intrinsic characteristics is described in 6.2.2, 6.2.3
or 6.2.4. For rules, see also Rule 2 (2.A to 2.E) in 7.4.2.2.
For datums with virtual conditions, see ISO 2692.
For the issue of orientation and location constraints in datum systems, see Annex I.
6 Subclause 6.2.2
Replace the whole 6.2.2 by the following.
The recommended status of the intrinsic characteristics for a single feature is:
— variable for the linear size of a feature of size (see Table 3);
— fixed for the angular size of a feature of size (see Table 3);
— fixed for an intrinsic characteristic which is not the size of a feature of size.
Table 3 — Recommended status of intrinsic characteristics of features of size
Feature of size Invariance class Intrinsic characteristic Recommended status
Cylinder Cylindrical Diameter Variable

Replace the first sentence by the following.
ISO 5459:2011/DAM 1:2022(E)
The recommended status (variable or fixed) of the intrinsic characteristics of each associated feature
establishing the datum system is as in 6.2.2.
9 Subclause 7.2.1
Replace the whole 7.2.1 by the following.
A single feature to be used as a datum feature shall be indicated in a single place by a datum feature
indicator. The datum feature indicator consists of a box connected to a filled datum triangle or an open
datum triangle by a leader line, and optional adjacent indications (see Figure 5).
NOTE There is no difference in meaning between a filled and an open datum triangle.

1 datum triangle
2 leader line
3 datum feature identifier area
4 adjacent indication area

10 Subclause 7.2.3.3
Replace twice "ISO 128-24:1999" by "ISO 128-2:2020".
11 Subclause 7.3
Replace the first paragraph by the following.
The datum (or datum system) is specified in the datum section of the tolerance indicator as described
in ISO 1101:2017, 8.2.
The datum (or datum system) is specified in an intersection plane indicator, or an orientation plane
indicator, or a direction feature indicator or a collection plane indicator as described in ISO 1101:2017,
Clauses 13 to 16.
See more details in Rule 6 in 7.4.2.6.
12 Subclause 7.4.2.1
In the first paragraph, replace the two first indents by the following.
— as an extension of a dimension line [see Figure 18 a) and Figure 18 b)];
ISO 5459:2011/DAM 1:2022(E)
— on a tolerance frame pointing to an extension of a dimension line for the surface [see Figure 18 e)
and Figure 18 f)];
Replace Figure 18 by the following.
Figure 18 — Attachment of a datum indicator for a single datum feature considered a feature of
size
In the paragraph after Figure 18, replace "complimentary" by "complementary".
Replace the four indents between Figure 18 and Figure 19 by the following.
— on the outline of the surface [see Figure 19 a)],
— on an extension line of the surface [see Figure 19 b)],
— on a reference line with a leader line having as terminator a dot [see Figure 19 c) for hidden surface
and Figure 19 d) for visible surface],
— on a tolerance frame pointing directly to the surface [see Figure 19 e)],
