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 5436-2 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This second edition cancels and replaces the first edition (ISO 5436-2:2001), which has been technically revised.
It also incorporates the Technical Corrigenda ISO 5436-2:2001/Cor.1:2006 and ISO 5436-2:2001/Cor.2:2008.
ISO 5436 consists of the following parts, under the general title Geometrical product specifications (GPS) —
Surface texture: Profile method; Measurement standards:
— Part 1: Material measures
— Part 2: Software measurement standards

Introduction
This part of ISO 5436 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 6 of the chain of standards on roughness, waviness
and primary profiles.
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 relationship of this part of ISO 5436 to other standards and the GPS
matrix model, see Annex B.
This part of ISO 5436, together with ISO 5436-1, introduces two new measurement standards:
— Type E, for calibrating the profile co-ordinate system;
— Type F, for calibrating software.
This part of ISO 5436 is concerned with software measurement standards.

1 Scope
This part of ISO 5436 defines Type F1 and Type F2 software measurement standards (etalons) for verifying the
software of measuring instruments. It also defines the file format of Type F1 software measurement standards for

NOTE 1 Throughout this part of ISO 5436, the term “softgauge” is used as a substitute for “software measurement
standard Type F1”.
NOTE 2 Formerly, “measurement standards” were referred to as “calibration specimens”.
NOTE 3 ISO 3274 only refers to instruments with independent reference datums.

4.2 Type F1 — Reference data
Type F1 measurement standards are computer data files that depict a digital representation of a primary profile
in a suitable recording medium.
Most of the operations between the total profile and primary profile are instrument-specific and, as a result, are
difficult to standardize. The primary profile is currently the first point where all the subsequent operations for
the definition of surface texture measurands are standardized and is thus chosen as the standardized point of
entry for type F1 softgauges.
A non-exhaustive, non-ordered, informative list of operations between the total profile and primary profile may
include the following.
— Adjustment for calibration — There are many different calibration models: gain factor, polynomial
corrections for curvilinear co-ordinates, interpolation method corrections for curvilinear co-ordinates, etc.
— Stylus tip correction — Corrects for the finite size and shape of the stylus.
— Decimation — Reduces the number of the data points for subsequent calculation.
— Equalization of interval of data points — Makes the data by using mathematical interpolation.
— Ls filtering — Convolutes with previous filtering (i.e. an anti-aliasing filter of an A/D convertor) to make a
true Gaussian filter.
— End effects — Removes a portion of the profile at the beginning and at the end to reduce possible end
effects due to, for example, Ls filtering, stylus tip correction, etc.
— Fitting of form by association — Total least squares, linear least squares, Chebychev (minimum zone),
fitting using robust norms (i.e. L1), one-sided fitting, Theil-Sen-type estimators.
— Removal of form from profile — Projection, orthogonal to line normal.
If the entry point for the F1 standard is before the primary profile (e.g. the total profile), the signal flow to
generate the primary profile (by steps like those exemplarily listed above) shall be agreed upon between the
producer and the user of the F1 standard.
NOTE The certified results for mathematically designed synthetic data can often be calculated directly without the
need for certification by Type F2 measurement standards.
4.3 Type F2 — Reference software
Type F2 measurement standards are reference software. Reference software consists of traceable computer
software against which software in a measuring instrument can be compared.
Type F2 measurement standards are used to test software by inputting a common data set into both the
software under test/calibration and the reference software, then comparing the results from the software under
test with the certified results from the reference software.
NOTE Type F2 measurement standards can also be used to certify Type F1 measurement standards.
Reference software values shall be traceable.
