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 13385-1 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This first edition of ISO 13385-1, together with ISO 13385-2, cancels and replaces ISO 3599:1976 and
ISO 6906:1984, which have been technically revised.
ISO 13385 consists of the following parts, under the general title Geometrical product specifications (GPS) —
Dimensional measuring equipment:
⎯ Part 1: Callipers; Design and metrological characteristics
⎯ Part 2: Calliper depth gauges; Design and metrological characteristics

ISO 13385-1:2011(E)
Introduction
This part of ISO 13385 is a geometrical product specification (GPS) standard and is to be regarded as a
general GPS standard (see ISO/TR 14638). It influences chain link 5 of the chains of standards on size and
distance in the general GPS matrix.
The ISO/GPS Masterplan given in ISO/TR 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.
For more detailed information on the relation of this part of ISO 13385 to other standards and the GPS matrix
model, see Annex G.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 14978, ISO/IEC Guide 99, and the
following apply.
3.1
calliper
measuring instrument which gives the evaluation of a dimensional quantity of an internal or external feature on
the basis of the movement of a slider with a measuring jaw, moving relative to a measuring scale on a rigid
beam and a fixed jaw
See Figures 1 and 2.
NOTE 1 Callipers with an additional measuring face at the end of the beam and a depth measuring rod are used for
depth measurements (see Figure 1).
NOTE 2 The indication may be either analogue (vernier), circular scale or digital. Regarding digital data transfer, see
4.3.3.
NOTE 3 See Annex C for examples of different types of callipers.
NOTE 4 See Annex D for examples of several types of measurements.
3.2
measuring face contact
contact between the measuring face and a feature of a workpiece
3.2.1
full measuring face contact
contact between the full area of the measuring face and a feature of a workpiece
3.2.2
partial measuring face contact
contact between a partial area of the measuring face and a feature of a workpiece
3.2.3
measuring face line contact
contact between a line, perpendicular to the length of the jaws, on the measuring face and a feature of a
workpiece
NOTE Form deviations in either the measuring face(s) or the feature are disregarded for the purposes of these
definitions.
4 Design characteristics
4.1 General design and nomenclature
The general design and workmanship of the calliper shall be such that its metrological characteristics comply
with this part of ISO 13385 under all operational orientations unless otherwise specified by the manufacturer.
See Figures 1 and 2 for general design.

4.3 Types of indicating devices
4.3.1 General
Several types of indicating devices exist:
⎯ analogue indicating devices with either a vernier scale or a circular scale (see Figures 3 and 8);
⎯ digital indicating devices with a digital display (see Figure 9).
On callipers with an analogue indicating device, the scale interval and its unit shall be labelled.
On callipers with a digital indicating device, the unit of the indication shall be labelled.
4.3.2 Analogue indicating devices
4.3.2.1 General
The scale interval of the main scale on the beam of a calliper with a vernier scale shall be 1 mm. The main
scale shall be longer by at least one vernier scale length than the measuring range of the calliper. In the case
of callipers with circular scales, the scale interval on the beam may be 1 mm or 2 mm (see Figure 8).
