Geometrical product specifications (GPS) - Surface texture: Areal - Part 73: Terms and definitions for surface defects on material measures (ISO 25178-73:2019)
This document defines classes of geometrical defects that might be present on the surfaces of material measures and calibration specimens conforming to ISO 5436-1 and ISO 25178-70, and defines terms for ways of responding to these defects.
This document is applicable as follows:
a) to help customers and users of material measures for surface metrology specify their nominal features (ideal geometrical properties) when obtaining them from manufacturers and suppliers;
b) to enable users of material measures to formulate their own rules and policies for responding to the occurrence of defects in such a way as to minimize the uncertainty of their own measurements;
NOTE Such policies are required in ISO/IEC 17025:2017, 7.2.1.1, 7.2.1.3, 7.3.1 and 7.8.5 c) and d), for example.
c) to enable calibration laboratories and their customers to agree on a common policy on how to treat defects on a material measure that has been sent for calibration;
d) to educate users of material measures about the different significance and importance of different kinds of defect;
e) for other GPS standards which make reference to the issue of selection of measuring locations, or selection of areas to be measured or avoided in measurement.

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.

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

Introduction
0.1 General
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 link F of the chain of standards on profile surface
texture, areal surface texture and surface imperfections.
The ISO GPS masterplan 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.
The default decision rules given in ISO 14253-1 apply to specifications made in accordance with this
document, unless otherwise stated.
For more detailed information on the relation of this document to the GPS matrix model, see Annex B.
This document is based on the premise that a material measure has a real geometrical surface which
is a realization of an ideal or nominal surface, which in turn can in most cases be regarded as a simple
mathematical concept: for example a plane, a sphere, a step function or a sinusoidal shape. In each
case there will be an associated precisely known quantity, which is used when the material measure is
measured by a surface texture-measuring instrument in one or more operations during the calibration
and set-up of that instrument.
Any portion of the measuring surface of the material measure at which the real surface deviates from
the ideal nominal surface is therefore more or less undesirable, and is here denoted by the term defect.
0.2 Relationship to ISO 8785
ISO 8785 was intended to apply to all types of surface, whether functional or otherwise. Examples
of functional surfaces are: brake disks, cylinder linings, optical lens and mirror surfaces, fluid pipe
couplings, marine propeller blades and artificial hip joints. In each case, the surface has to perform one
or more definite jobs and, consequently, the choice of method of manufacture and the type of surface
geometry, together with a certain range of parameter values which are specified for it, are usually a
compromise between conflicting requirements which might not all be perfectly fulfilled. The functional
surface can then be measured in order to find out how closely it matches the parameter values which
have been specified.
However, this is not the same as determining how well the surface functions. In many cases it is not
obvious exactly what the ideal profile shape from the point of view of best function would be. Therefore,
it is possible that a surface which deviates from the specified profile in some places actually performs
better than one which has no deviations. For this reason, ISO 8785 used the general term imperfections,
which does not suggest undesirability, in preference to the term defects, which does suggest this.
Unlike ISO 8785, this document does not deal with any classes of defect, other than geometrical, that
might appear upon the surfaces of material measures. Examples of other classes of defect are: unwanted
variations in such physical properties as:
— surface hardness;
— surface colour;
— electrical properties.
For the purposes of this document, no instance of such an unwanted variation in a physical property
is considered to be a defect unless it coincides spatially with the area of a geometrical defect. For
