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

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.

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).

The CEN Secretary-General has advised the ISO Secretary-General that this ISO/DIS covers a subject
of interest to European standardization. In accordance with the ISO-lead mode of collaboration as
defined in the Vienna Agreement, consultation on this ISO/DIS has the same effect for CEN
members as would a CEN enquiry on a draft European Standard. Should this draft be accepted, a
final draft, established on the basis of comments received, will be submitted to a parallel two-month FDIS
vote in ISO and formal vote in CEN.
To expedite distribution, this document is circulated as received from the committee secretariat.
ISO Central Secretariat work of editing and text composition will be undertaken at publication
stage.
Pour accélérer la distribution, le présent document est distribué tel qu'il est parvenu du

THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE
REFERRED TO AS AN INTERNATIONAL STANDARD UNTIL PUBLISHED AS SUCH.
IN ADDITION TO THEIR EVALUATION AS BEING ACCEPTABLE FOR INDUSTRIAL, TECHNOLOGICAL, COMMERCIAL AND USER PURPOSES, DRAFT
INTERNATIONAL STANDARDS MAY ON OCCASION HAVE TO BE CONSIDERED IN THE LIGHT OF THEIR POTENTIAL TO BECOME STANDARDS TO

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 3.
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 part of ISO 13385 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
specification and verification.
This second edition cancels and replaces ISO 3599:1976 and ISO 6906:1984 of which has been technically
revised.
ISO 13385 consists of the following parts, under the general title Geometrical product specification (GPS) —
Dimensional measuring equipment:
Part 1: Callipers; Design and metrological requirements
Part 2: Calliper depth gauges; Design and metrological requirements

Introduction
This International Standard 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.
For more detailed information on the relation of this standard to other standards and the GPS matrix model see
Annex F.
ISO 14978 should also be available when reading this standard.

Calliper design and metrological requirements
1 Scope
This International Standard provides the most important design and metrological characteristics of callipers
with analogue indication: vernier scale or circular scale (dial)
with digital indication: digital display

3 Terms and definitions
For the purposes of this part of ISO 13385, the terms and definitions given in ISO 14978, VIM, and the following
apply.
3.1
calliper
measuring instrument which measures on the basis of the movement of a slider with a measuring jaw, moving
relatively to a measuring scale on a 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 called universal
callipers (see figure 1).
NOTE 2 The indication may be analogue or by a digital display. Regarding data transfer see clause 4.3.2.
NOTE 3 Callipers are suitable for external and internal measurements, universal callipers may be used to make many types
of measurement. The slider of a universal calliper may be developed to measure heights or steps (see Annex D).
4 Design characteristics
4.1 General design and nomenclature
The general design and workmanship shall be such that the metrological characteristics of the calliper comply with
this standard under all orientation of operation unless otherwise specified by the manufacturer.
Nomenclature see figure 1 and 2.
