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 25178-3 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
ISO 25178 consists of the following parts, under the general title Geometrical product specifications (GPS) —
Surface texture: Areal:

Introduction
This part of ISO 25178 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 3 of the chains of standards on areal surface texture.
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 25178 to the GPS matrix model, see Annex E.
This part of ISO 25178 specifies the specification operators according to ISO 17450-2.

4 Complete specification operator
4.1 General
The complete specification operator (see ISO 17450-2) consists of all the operations required for an unambiguous
specification. It consists of a full set of unambiguous specification operations in an unambiguous order. For
areal surface texture, the complete specification operator defines the type of surface, method of extraction,
association method and filtration for surface texture by areal methods.
If form error is to be included in the measurand, then a S-F surface shall be specified; otherwise, an S-L
surface shall be specified.
4.2 Method of extraction
4.2.1 Evaluation area
4.2.1.1 General
The evaluation area consists of a rectangular portion of the surface over which an extraction is made.
The orientation of the evaluation area shall be controlled by the specification.
NOTE 1 If the nesting index is the same in orthogonal directions, then the orientation does not matter.
NOTE 2 The orientation of the evaluation area is typically influenced by the form; this means that the sides of the
rectangular area are parallel/orthogonal to the nominal geometry (e.g. cylinder axis, sides of a rectangular flat, etc.).
4.2.1.2 S-F surface
For an S-F surface, if not otherwise specified, the evaluation area shall be a square.
If the F-operation is a filtration operation, then the length of the sides of the square evaluation area is the same
length as the filter “nesting index”.
If the F-operation is an association operation, then the length of the side of the square evaluation area is used
as a substitute for the F-operation nesting index value. This chosen value for the F-operation nesting index is
used for all subsequent operations.
The value of the nesting index for the F-operation is normally chosen from the following series:
...; 0,1 mm; 0,2 mm; 0,25 mm; 0,5 mm; 0,8 mm; 1,0 mm; 2,0 mm; 2,5 mm; 5,0 mm; 8,0 mm; 10 mm; ...
NOTE 1 An example of an F-operation with a nesting index is a spline filter. The total least squares fit of the nominal
form is an example of an F-operation without a predefined nesting index.
NOTE 2 The value of the F-operation nesting index is typically chosen to be five times the scale of the coarsest
structure of interest.
4.2.1.3 S-L surface
For an S-L surface, if not otherwise specified, the evaluation area shall be a square whose sides are the same
length as the L-filter nesting index value.
The value of the nesting index for the L-filter is normally chosen from the following series:
...., 0,1 mm; 0,2 mm; 0,25 mm; 0,5 mm; 0,8 mm; 1,0 mm; 2,0 mm;2,5 mm; 5,0 mm; 8,0 mm; 10 mm; ...
NOTE The value of the L-filter nesting index is typically five times the scale of the coarsest structure of interest.
