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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 213, Dimensional and geometrical product
specifications and verification.

Introduction
This part of ISO 16610 is a geometrical product specification (GPS) standard and is to be regarded as a
general GPS standard (see ISO/TR 14638). It influences chain links 3 and 5 in the GPS matrix structure.
The ISO/GPS Masterplan given in ISO 14638 gives an overview of the ISO/GPS system of which this
part of ISO 16610 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of
ISO 16610 and the default decision rules given in ISO 14253-1 apply to specifications made in accordance
with this part of ISO 16610, unless otherwise indicated.
For more detailed information about the relation of this part of ISO 16610 to the GPS matrix model, see
Annex B.
This part of ISO 16610 provides guidelines for computing profile morphological operations and filters
with disk and horizontal segment structuring elements. It also describes techniques for applying
morphological filters, including envelope filters, for open profiles.
