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 13225 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.

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 the chain link 5 of the chain of standards on size and distance.
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 of the relation of this International Standard to the GPS matrix model, see Annex D.
This International Standard is intended to serve the purpose of promoting
— the relationship between the manufacturer and purchaser, and
— the management of measuring instruments in the quality-assurance system.

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
height gauge
measuring instrument in which a slider with a measuring stylus moves relative to a measuring scale on a beam
and in which this motion is along a single vertical axis nominally perpendicular to a reference plane on the
instrument base
NOTE 1 Height gauges are designed to be used with surface plates in which the reference plane of the height gauge
is placed in contact with the surface plate.
NOTE 2 Various types of measuring scales on the beam with appropriate indication are possible, such as analogue
indication, including vernier and circular scales, and digital indication.
NOTE 3 Most height gauges are capable of using various types of measuring styli, including a scriber.

ISO 13225:2012(E)
NOTE 4 Height gauges are sometimes equipped with motorized motion of the slider, while on others the slider can only
be moved by hand (manually).
NOTE 5 Height gauges are sometimes equipped with a device to control the measuring force.
NOTE 6 Height gauges are sometimes designed only for measuring distances parallel to the beam while others
have measuring devices which allow for more complex measurements, including scanning functions and measurements
perpendicular to the beam.
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
4 Design characteristics
4.1 General design and nomenclature
The general design and workmanship of the height gauge shall be such that its metrological characteristics
comply with the requirements of this International Standard, unless otherwise specified by the manufacturer.
The height gauge can be manually moved on a surface plate. Between the height gauge and surface plate
there may be
— mechanical contact, or
— an air bearing system.
The general terms related to the structure of the height gauge are given and illustrated in Figures 1 and 2. The
representations given in Figures 1 and 2 are only examples of height gauge design.

4.3.1 General
Several types of indicating devices are possible:
— analogue indicating devices with a vernier scale or circular scale (see Figures 4 and 9);
— digital indicating devices with digital display (see Figure 10).
NOTE Combinations of these types of indicating devices are possible.
On instruments with analogue indicating devices, the scale interval and its unit shall be labelled.
On instruments with digital indicating devices, the unit of the indication shall be labelled.
4.3.2 Analogue indicating devices with a vernier scale
4.3.2.1 General
The scale interval of the main scale on the beam of an instrument with a vernier scale shall be specified in millimetres.
The main scale shall be longer, by at least one vernier scale length, than the measuring range of the instrument.
In the case of instruments with circular scales, the scale interval on the beam may be greater than 1 mm.
