This draft amendment is submitted to CEN members for parallel enquiry. It has been drawn up by the Technical Committee CEN/TC 290.

This draft amendment A1, if approved, will modify the European Standard EN ISO 3040:2012. If this draft becomes an amendment, CEN
members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this amendment
into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has
the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United
Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are aware and to
provide supporting documentation.

ISO/CEN PARALLEL PROCESSING
This draft has been developed within the International Organization for Standardization (ISO), and
processed under the ISO-lead mode of collaboration as defined in the Vienna Agreement.
This draft is hereby submitted to the ISO member bodies and to the CEN member bodies for a parallel
five-month enquiry.
Should this draft be accepted, a final draft, established on the basis of comments received, will be
submitted to a parallel two-month approval vote in ISO and formal vote in CEN.

To expedite distribution, this document is circulated as received from the committee
secretariat. ISO Central Secretariat work of editing and text composition will be undertaken at
publication stage.
Pour accélérer la distribution, le présent document est distribué tel qu'il est parvenu du
secrétariat du comité. Le travail de rédaction et de composition de texte sera effectué au
Secrétariat central de l'ISO au stade de publication.

THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE
REFERRED TO AS AN INTERNATIONAL STANDARD UNTIL PUBLISHED AS SUCH.
IN ADDITION TO THEIR EVALUATION AS BEING ACCEPTABLE FOR INDUSTRIAL, TECHNOLOGICAL, COMMERCIAL AND USER PURPOSES,
DRAFT INTERNATIONAL STANDARDS MAY ON OCCASION HAVE TO BE CONSIDERED IN THE LIGHT OF THEIR POTENTIAL TO BECOME
STANDARDS TO WHICH REFERENCE MAY BE MADE IN NATIONAL REGULATIONS.
RECIPIENTS OF THIS DRAFT ARE INVITED TO SUBMIT, WITH THEIR COMMENTS, NOTIFICATION OF ANY RELEVANT PATENT RIGHTS OF WHICH
THEY ARE AWARE AND TO PROVIDE SUPPORTING DOCUMENTATION.

ISO 3040:2009/DAM 1
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.
Amendment 1 to ISO 3040:2009 was prepared by Technical Committee ISO/TC 213, Dimensional and
geometrical product specifications and verification.
DRAFT AMENDMENT ISO 3040:2009/DAM 1

Geometrical product specifications (GPS) — Dimensioning and
tolerancing — Cones
Replace clause 6 "Tolerancing of cones" by the following:
A cone is intrinsically defined by its angle (see Figure 9).

θ
φD
L
Figure 9 – Intrinsic representation of a cone
NOTE A cone is different from a frustum which is defined by three geometrical entities (one of them is a cone).
EXAMPLE "A frustum defined by a cone and two end planes (not necessarily perpendicular to the axes of this cone).

Tolerancing controls deviations from the nominal definition observed on a real workpiece. The shape of the
cone cannot be perfect. The size of the cone (its angle) cannot be equal to the nominal value. Orientation
and/or the location of the cone from other features can also deviate from the nominal target value.
The objective of tolerancing is to define a set of one or more GPS specifications. Each GPS specification
defines a particular characteristic and its permissible extent by the mean of one or two tolerances limits (see
Figure 9).
When a section plane is used in a specification, the section plane location shall be defined by TEDs (explicit
or implicit: 0 mm).
When a datum or datum system is used to locate or orientate the tolerance zone, the dimensions constraining
the tolerance zone shall be defined by TEDs (explicit or implicit :0 mm, 0°, 90 °, 180°, 270°).
ISO 3040:2009/DAM 1
Each characteristic controls a set of degrees of freedom on the real workpiece.
The set of degrees of freedom, which are possible to consider individually or collectively, is:
⎯ the angle deviation;
⎯ the form deviation on a section line or the surface;
⎯ the location deviation (X, Y, Z : in Cartesian system);
⎯ the orientation devia
