ISO/TS 12180-1:2003(E)
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.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of normative document:
 an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in
an ISO working group and is accepted for publication if it is approved by more than 50 % of the members
of the parent committee casting a vote;
 an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical
committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting
a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a
further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is
confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an
International Standard or be withdrawn.
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/TS 12180-1 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product
specifications and verification.
ISO/TS 12180 consists of the following parts, under the general title Geometrical Product Specifications
(GPS) — Cylindricity:
 Part 1: Vocabulary and parameters of cylindrical form
 Part 2: Specification operators

ISO/TS 12180-1:2003(E)
Introduction
This part of ISO/TS 12180 is a geometrical product specification (GPS) Technical Specification and is to be
regarded as a general GPS document (see ISO/TR 14638). It influences chain link 2 of the chain of standards
on form of a surface (independent of a datum).
For more detailed information on the relation of this part of ISO/TS 12180 to other standards and the GPS
matrix model, see Annex D.
This part of ISO/TS 12180 defines terms and concepts necessary for defining the specification operators
according to ISO/TS 17450-2 for cylindricity of integral features.
Extracting data will always involve applying a certain filtering process. An additional filtering of the extracted
data may or may 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 will influence the definition of cylindricity
and the specification operators and, therefore, needs to be stated unambiguously.
This part of ISO/TS 12180 is not intended to disallow any means of measuring cylindricity.

LCD
deviation of a point on a cylindricity surface from the reference cylinder, the deviation being normal to the
