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 12780-1 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
This first edition of ISO 12780-1 cancels and replaces ISO/TS 12780-1:2003, which has been technically
revised.
ISO 12780 consists of the following parts, under the general title Geometrical product specifications (GPS) —
Straightness:
⎯ Part 1: Vocabulary and parameters of straightness
⎯ Part 2: Specification operators

Introduction
This part of ISO 12780 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 2 of the chain of standards on form of line
independent of datum.
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 of the relationship of this part of ISO 12780 to other standards and the GPS
matrix model, see Annex C.
This part of ISO 12780 defines terms and concepts necessary for defining the specification operators
according to ISO 17450-2 for straightness of integral features.
Extracting data always involves applying a certain filtering process. An additional filtering of the extracted data
might or might not be applied. This additional filter can be a mean line filter (Gaussian, spline, wavelet, etc.) or
a non-linear filter (e.g. morphological filter). The type of filtering influences the definition of straightness and
the specification operators and, therefore, needs to be stated unambiguously.
This part of ISO 12780 is not intended to disallow any means of measuring straightness.
