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.

The committee responsible for this document is Technical Committee ISO/TC 213, Dimensional and
geometrical product specifications and verification.
ISO 14405 consists of the following parts, under the general title Geometrical product specification
(GPS) — Dimensional tolerancing:
— Part 1: Linear sizes

ISO 14405-3:2016(E)
Introduction
This part of ISO 14405 is a geometrical product specification (GPS) standard and is to be regarded as a
general GPS standard (see ISO 14638). In the general GPS matrix, it influences chain links “Symbols and
indications”, “Feature requirements” and “Feature properties” of the size chain of standards.
The ISO/GPS Masterplan given in ISO 14638 gives an overview of the ISO/GPS system of which this
part of ISO 14405 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of
ISO 14405 and the default decision rules given in ISO 14253-1 apply to specifications made in accordance
with this part of ISO 14405, unless otherwise indicated.
For more detailed information on the relation of this part of ISO 14405 to other standards and to the
GPS matrix model, see Annex D.

tolerancing —
Part 3:
Angular sizes
1 Scope
This part of ISO 14405 establishes the default specification operator for angular size and defines a
number of special specification operators for features of angular size: cone (truncated, i.e. frustum, or
not), wedge (truncated or not), two opposite straight lines (intersection of a wedge/truncated wedge and
a plane perpendicular to the intersection straight line of the two planes of the wedge/truncated wedge,
intersection of a cone/frustum and a plane containing the axis of revolution of the cone/frustum). See
Figure 1 and Figure 2.
This part of ISO 14405 also defines the specification modifiers and the drawing indications for these
angular sizes.
This part of ISO 14405 covers the following angular sizes:
— local angular size:
— angular size between two lines;
— portion angular size;
— global angular size:
— direct global angular size:
— least squares angular size;
— minimax angular size;
— rank order angular size/indirect global angular size:
— maximum angular size;
— minimum angular size;
— average angular size;
— range of angular sizes;
— mid-range angular size;
— median angular size;
— standard deviation of angular size.
This part of ISO 14405 defines the meaning of tolerances of angular sizes indicated as
— + and/or - limit deviations, e.g. 0°/-0,5°, or
— indicated with upper limit of size (ULS) and/or lower limit of size (LLS), e.g. 35° max. or 15° min.,
34°/36°,
