Geometrical product specifications (GPS) - Surface texture: Areal - Part 71: Software measurement standards (ISO 25178-1:2017)

ISO 25178-71:2017 defines Type S1 and Type S2 software measurement standards (etalons) for verifying the software of measuring instruments. It also defines the file format of Type S1 software measurement standards for the calibration of instruments for the measurement of surface texture by the areal method as defined in the areal surface texture chain of standards, chain link G.
NOTE Throughout ISO 25178-71:2017, the term "softgauge" is used as a substitute for "software measurement standard Type S1".

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.

The procedures used to develop this document and those intended for its further maintenance are

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

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

This second edition cancels and replaces the first edition (ISO 25178-71:2012), which has been

technically revised.
The main changes compared to the previous edition are as follows:
— the definition of 3.7 has been changed;
— Table 1 has been changed.

Introduction

This document is a geometrical product specification (GPS) standard and is to be regarded as a general

GPS standard (see ISO 14638). It influences the chain link G of the chains of standards on profile and

areal surface texture.

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 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 document to the GPS matrix model, see Annex B.

This document is concerned with software gauges (Type S1) and reference software (Type S2). It also

defines the SDF file format for Type S1 software gauges.

The surface data file (SDF) format is already used by the industry, in particular, by instrument

manufacturers and academia. The SDF file format as defined in this document is a standardized sub-set

of the possibilities included in the SDF file format as initially defined in the European Surfstand project

and EUR15178. It is envisaged that the SDF file format could evolve (as more experience in its usage and

future requirements are identified) later in a version 2.0 with additional fields and possibilities.

1 Scope

This document defines Type S1 and Type S2 software measurement standards (etalons) for verifying

the software of measuring instruments. It also defines the file format of Type S1 software measurement

standards for the calibration of instruments for the measurement of surface texture by the areal

method as defined in the areal surface texture chain of standards, chain link G.

NOTE Throughout this document, the term “softgauge” is used as a substitute for “software measurement

standard Type S1”.
