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 second edition cancels and replaces the first edition (ISO 13385-1:2011), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— figures have been updated to show more modern technology;
— general design characteristics have been removed and reference to ISO 14978:2018 included;
— metrological characteristics have been clarified and modified;
— requirements for test methods have been included;
— default values for maximum permissible errors have been added.

Introduction
This document is a geometrical product specification (GPS) standard and is to be regarded as a general
GPS standard (see ISO 14638). It influences the chain links F and G of the chain of standards on size and
distance in the general GPS matrix (see Annex C).
The ISO/GPS matrix model given in ISO 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; see ISO/TR 14253-6 for additional information on the selection
of alternative decision rules.
For more detailed information on the relation of this document to other standards and the GPS matrix
model, see Annex C.

3.1
calliper
measuring instrument which evaluates a dimensional quantity of an internal or external feature on
the basis of opposing contact from the movement of a slider with a measuring jaw, moving relative to a
measuring scale on a rigid beam and to a fixed jaw
Note 1 to entry: See examples in Figures 1, 2 and 3.
Note 2 to entry: Callipers can be equipped for additional measurements, such as depth and step measurements
(see Figures 1 and 2).
Note 3 to entry: The indication can be either analogue (vernier scale or circular scale) or digital.
3.2
measuring face contact
contact between the measuring face and an integral feature of a workpiece
3.2.1
full measuring face contact
contact between the full area of the measuring face and an integral feature of a workpiece
3.2.2
partial measuring face contact
contact between a partial area of the measuring face and an integral feature of a workpiece
3.2.3
measuring face line contact
contact between a line, nominally perpendicular to the length of the jaws, on the measuring face and an
integral feature of a workpiece
4 Design characteristics
4.1 General design and nomenclature
The design shall follow the general guidelines in ISO 14978, including the common design characteristics
in ISO 14978:2018, Annex C. Examples of the general design of callipers are shown in Figures 1, 2 and 3.
The scale interval of the main scale on the beam of a calliper with a vernier scale shall be 1 mm. In the
case of callipers with circular scales, the scale interval on the beam shall be either 1 mm or 2 mm.
4.2 Dimensions
The manufacturer shall state important calliper design dimensions, such as those shown in Table 1. The
values shown in Table 1 are typical dimensions of the elements of callipers and are not requirements of
this document. Table 1 does not include the length of the undercut, which is typically kept as small as
practicable.
For callipers equipped with a depth measuring rod, the manufacturer shall state the cross-sectional
dimensions of the rod, for example ∅ 1,5 mm for round section or 1,2 mm × 3 mm for rectangular
section.

3.1
calliper
measuring instrument which evaluates a dimensional quantity of an internal or external feature on
the basis of opposing contact from the movement of a slider with a measuring jaw, moving relative to a
measuring scale on a rigid beam and a fixed jaw
Note 1 to entry: See examples in Figures 1, 2 and 3.
Note 2 to entry: Callipers may be equipped for additional measurements, such as depth and step measurements
(see Figures 1 and 2).
Note 3 to entry: The indication may be either analogue (vernier scale or circular scale) or digital.
3.2
measuring face contact
contact between the measuring face and an integral feature of a workpiece
3.2.1
full measuring face contact
contact between the full area of the measuring face and an integral feature of a workpiece
3.2.2
partial measuring face contact
contact between a partial area of the measuring face and an integral feature of a workpiece
3.2.3
measuring face line contact
contact between a line, nominally perpendicular to the length of the jaws, on the measuring face and an
integral feature of a workpiece
4 Design characteristics
4.1 General design and nomenclature
See Figures 1, 2 and 3 for general design.
The design shall follow the general guidelines in ISO/DIS 14978:2017 including the common design
characteristics in ISO/DIS 14978:2017, Annex D.
The scale interval of the main scale on the beam of a calliper with a vernier scale shall be 1 mm. In the
case of callipers with circular scales, the scale interval on the beam shall be either 1 mm or 2 mm.
4.2 Dimensions
The manufacturer shall state important calliper design dimensions, such as those shown in Table 1. See
Annex B. The values shown in Table 1 are typical dimensions of the elements of callipers and are not
requirements of this document. Table 1 does not include the length of the undercut, l , which is typically
u
kept as small as practicable.
For callipers equipped with a depth measuring rod, the manufacturer shall state the cross-sectional
dimensions of the rod, e.g. ∅ 1,5 mm for round or 1,2 mm x 3 mm for rectangular.

5 Metrological characteristics
5.1 General
The metrological characteristics and associated maximum permissible error (MPE) values apply to any
indications under the following conditions, unless otherwise stated by the manufacturer:
— used in accordance with the manufacturer recommendations;
— used anywhere within the measuring range of the calliper;
— reference point stated in 5.3;
— all unique indications – averaging of several indications, or other data treatment, is not permitted.
The maximum permissible errors cannot be smaller than the digital step or the scale interval on the
circular scale or vernier scale.
