Guidelines on the completion of a proposal for a new work item (see also the ISO/IEC Directives Part 1) a) Title: Indicate the subject of the proposed new work item. b) Scope: Give a clear indication of the coverage of the proposed new work item. Indicate, for example, if this is a proposal for a new document, or a proposed change (amendment/revision). It is often helpful to indicate what is not covered (exclusions). c) Envisaged publication type: Details of the types of ISO deliverable available are given in the ISO/IEC Directives, Part 1 and/or the associated ISO Supplement. d) Purpose and justification: Give details based on a critical study of the following elements wherever practicable. Wherever possible reference should be made to information contained in the related TC Business Plan. 1) The specific aims and reason for the standardization activity, with particular emphasis on the aspects of standardization to be covered, the problems it is expected to solve or the difficulties it is intended to overcome. 2) The main interests that might benefit from or be affected by the activity, such as industry, consumers, trade, governments, distributors. 3) Feasibility of the activity: Are there factors that could hinder the successful establishment or general application of the standard? 4) Timeliness of the standard to be produced: Is the technology reasonably stabilized? If not, how much time is likely to be available before advances in technology may render the proposed standard outdated? Is the proposed standard required as a basis for the future development of the technology in question? 5) Urgency of the activity, considering the needs of other fields or organizations. Indicate target date and, when a series of standards is proposed, suggest priorities. 6) The benefits to be gained by the implementation of the proposed standard; alternatively, the loss or disadvantage(s) if no standard is established within a reasonable time. Data such as product volume or value of trade should be included and quantified. 7) If the standardization activity is, or is likely to be, the subject of regulations or to require the harmonization of existing regulations, this should be indicated. If a series of new work items is proposed having a common purpose and justification, a common proposal may be drafted including all elements to be clarified and enumerating the titles and scopes of each individual item. e) Relevant documents: List any known relevant documents (such as standards and regulations), regardless of their source. When the proposer considers that an existing well-established document may be acceptable as a standard (with or without amendment), indicate this with appropriate justification and attach a copy to the proposal. f) Cooperation and liaison: List relevant organizations or bodies with which cooperation and liaison should exist.

4 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 or nongovernmental, 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 3. 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 Amendment 2 to International Standard ISO 1101:2001 was prepared by the Technical Committee ISO/TC 213, Dimensional and geometrical product specifications and verification. Annex A is for information only. iii

5 Introduction This International Standard is a geometrical product specification (GPS) standard and is to be regarded as a global GPS standard (see ISO/TR 14638). It influences the chain link 1 of the chains of standards on Form of line independent of datum, Form of line dependent of datum, Form of surface independent of datum, Form of surface dependent of datum, Orientation, Location, Circular run-out, Total run-out and Datums in the general GPS matrix. For more detailed information of the relation of this standard to other standards and the GPS matrix model see Annex A. Excerpt from AG 11 Resolution from Berlin 2000 This completed version should be prepared in a way that allows it to not only work for form, but also be extended to address the needs in connection with other indications (e.g. location, orientation) and indications that include datums. The indication technique shall complement that of ISO iv

NOTE 1 The missing definition of these default operators means that the use of ISO basic GPS specification for straightness, roundness, flatness and cylindricity (Alternatively: form, orientation, location and run-out) may introduce specification uncertainty. The consequence of the fact, that default specification operators are not yet defined in ISO standards, is, that the specification operator shall be indicated on the TPD as the complete special specification operator to avoid specification uncertainty. NOTE 2 The indication of national or company default specification operators on the TPD (see ISO 14659) may be a solution to avoid specification uncertainty, when using ISO basic specification is used in the TPD indication. 4.2 Form The ISO basic GPS specification for form contains only the tolerance value and sometimes also the indication of a cylindrical tolerance zone ( ) in the second compartment of the tolerance indicator - see figure Orientation 0,1 0,1 0,02 0,4 0,8 0,06 Figure 1 Examples of ISO basic indication for form The ISO basic GPS specification for orientation contains only the tolerance value and sometimes also the indication of a cylindrical tolerance zone ( ) in the second compartment of the tolerance indicator - see figure 2. 0,1 A 0,2 A D 0,04 B-C 0,3 B 0,02 Figure 2 Examples of ISO basic indication for orientation A B-C 2) To be published 2

8 4.4 Location The ISO basic GPS specification for location contains only the tolerance value and sometimes also the indication of a cylindrical or spherical tolerance zone ( or S ) in the second compartment of the tolerance indicator - see figure Run-out 0,2 B D E 0,4 A 0,04 A-B 0,3 A D B 0,5 C G F Figure 3 Examples of ISO basic indication for location The ISO basic GPS specification for run-out contains only the tolerance value in the second compartment of the tolerance indicator - see figure 4. 0,05 G-C 0,3 B F Figure 4 Examples of ISO basic indication for run-out 5 Special specification operator indication on the TPD 5.1 General The special specification operator is indicated in the second compartment of the tolerance indicator. The format of the indication is: - Tolerance value in mm, followed by a space - Parameter designation, followed by a semicolon and a space Parameters are only defined for form characteristics. For orientaion, location and run-out no parameter shall be indicated. The tolerance value for these characteristics are defined as peak-to-valley deviation for orientation and run-out and 2 x max deviation from ideal location for location. - Indication of association criteria, followed by a semicolon and a space NOTE 1 Only applicable for form (see ISO/TS , , and ) - Indication of filter type (see table 1), followed by a space - Filter cut-off 1/size 1, dash, filter cut-off 2/size 2. Cut-off and size in mm. For circumference in UPR. If the cut-off values are given for circumference the unit UPR is stated after the value(s). If the cut-off values are given in mm, no unit is indicated after the value(s) If one of the filters is not indicated, then the cut-off or size is either zero or infinity. NOTE 2 All the filters given in table 1 are profile filters. Areal filters are not yet defined. In case the toleranced feature is a surface two different filters may be stated. For a cylinder or a cone the filter direction is the circumference and the generating lines. In other cases the filter directions shall be indicated graphically (symbol to be defined!!) on the drawing or given in a text note adjacent to the tolerance indication. 3
