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/

This document was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification, in collaboration with the European Committee for Standardization (CEN)
Technical Committee CEN/TC 290, Dimensional and geometrical product specification and verification, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 13385-2:2011), which has been technically
revised.
The main changes 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 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.

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 D. Examples of the general design of calliper depth gauges are shown in
Figures 1 and 2.
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.
