(ISO member bodies) The work o f 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 o f electrotechnical standardization The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part In particular the different approval criteria needed for the di fferent types o f ISO documents should be noted This document was dra fted in accordance with the editorial rules of the ISO/IEC Directives, Part (see www.iso org/directives) Attention is drawn to the possibility that some o f the elements o f this document may be the subject o f patent rights ISO shall not be held responsible for identi fying any or all such patent rights Details o f any patent rights identified during the development o f 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 in formation given for the convenience o f users and does not constitute an endorsement For an explanation on the meaning o f ISO specific terms and expressions related to formity assessment, as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html This document was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product specifications and verifications This fourth edition cancels and replaces the third edition (ISO 1101:2012), which has been technically revised It also incorporates the Technical Corrigendum ISO 1101:2012/Cor.1:2013 The main changes are as follows — Tools have been added to speci fy the filtering o f the toleranced feature and a line type has been designated for its illustration — Tools have been added to tolerance associated features — Tools have been added to speci fy form characteristics by speci fying the re ference feature association and the specified parameter — Tools have been added to speci fy the constraints to the tolerance zone — The rules for specifications using “all around” or “all over” modifiers have been clarified — The direction of the tolerance zone in the case of roundness tolerances for revolute surfaces that are neither cylindrical nor spherical, e.g cones shall now always be indicated to avoid an exception to the general rule that specifications for integral features apply perpendicular to the sur face — The “ from-to” symbol has been retired and replaced by the “between” symbol vi © ISO 2017 – All rights reserved ISO 1 01 : 01 7(E) Introduction This document is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO 14638) It influences chain links A, B and C o f the chain o f standards on form, orientation, location and run out The ISO GPS Masterplan given in ISO 14638 gives an overview o f the ISO GPS system o f which this document is a part The fundamental rules o f ISO GPS given in ISO 8015 apply to this document The de fault decision rules given in ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise stated For more detailed information on the relation of this document to the GPS matrix model, see Annex G This document represents the initial basis and describes the required fundamentals for geometrical tolerancing Nevertheless, it is advisable to consult the separate standards referenced in Clause and in Tables and for more detailed information For the presentation of lettering (proportions and dimensions), see ISO 3098-2 All figures in this document for the 2D drawing indications have been drawn in first-angle projection with dimensions and tolerances in millimetres It should be understood that third-angle projection and other units o f measurement could have been used equally well without prejudice to the principles established For all figures giving specification examples in 3D, the dimensions and tolerances are the same as for the similar figures shown in 2D The figures in this document represent either 2D drawing views or 3D axonometric views on 2D drawings and are intended to illustrate how a specification can be fully indicated with visible annotation For possibilities o f illustrating a specification where elements o f the specification may be available through a query function or other interrogation o f in formation on the 3D CAD model and rules for attaching specifications to 3D CAD models, see ISO 16792 The figures in this document illustrate the text and are not intended to reflect an actual application Consequently, the figures are not fully dimensioned and specified, showing only the relevant general principles Neither are the figures intended to imply a particular display requirement in terms o f whether hidden detail, tangent lines or other annotations are shown or not shown Many figures have lines or details removed for clarity, or added or extended to assist with the illustration o f the text See Table for the line types used in definition figures In order for a GPS specification to be unambiguous, the partition defining the boundary o f the toleranced eature, as well as the filtering, has to be well defined Currently, the detailed rules for partitioning and the de fault for filtering are not defined in GPS standards f For a definitive presentation (proportions and dimensions) o f the symbolization for geometrical tolerancing, see ISO 7083 and Annex F Annex A has been provided for in formation only It presents previous drawing indications that have been omitted here and are no longer used For the purposes o f this document, the terms “axis” and “median plane” are used for derived features o f per fect form, and the terms “median line” and “median sur face” for derived features o f imper fect form Furthermore, the following line types have been used in the explanatory illustrations, i.e those representing non-technical drawings for which the rules o f ISO 128 (all parts) apply © ISO 2017 – All rights reserved vii ISO 1 01 : 01 7(E) Table Feature level Feature type integral feature Nominal feature

The illustrations included in this document are intended to illustrate the text and/or to provide examples o f the related technical drawing specification; these illustrations are not fully dimensioned and toleranced, showing only the relevant general principles In particular, many illustrations not contain filter specifications As a consequence, the illustrations are not a representation o f a complete workpiece, and are not o f a quality that is required for use in industry (in terms o f full formity with the standards prepared by ISO/TC 10 and ISO/TC 213), and as such are not suitable for projection for teaching purposes Scope This document defines the symbol language for geometrical specification o f workpieces and the rules for its interpretation It provides the foundation for geometrical specification The illustrations in this document are intended to illustrate how a specification can be fully indicated with visible annotation (including e.g TEDs) NOTE Other International Standards referenced in Clause and in Tables and provide more detailed information on geometrical tolerancing NOTE This document gives rules for explicit and direct indications o f geometrical specifications Alternatively, the same specifications can be indicated indirectly in accordance with ISO 16792 by attaching them to a 3D CAD model In this case, it is possible that some elements o f the specification are available through a query function or other interrogation o f in formation on the model instead o f being indicated using visible annotation Normative references The

01 7(E) Figure E.16 shows an example of a cylindricity specification The specification element G indicates that a Gaussian filter is specified Because it is a cylindricity specification, the toleranced feature is an open feature in the axial direction and a closed feature in the circumferential direction The nesting index in the axial direction is therefore given in mm and the nesting index in the circumferential direction is given in UPR By convention, the axial filter value is given be fore the circum ferential filter value The value therefore indicates mm and the value 15 indicates 15 UPR Because each of them is followed by “-” they are both long-wave pass filters The specification there fore applies to a feature that has been filtered with an mm Gaussian long-wave pass filter in the axial direction and a 15 UPR Gaussian longwave pass filter in the circum ferential direction The filtered sur face shall be contained in a tolerance zone defined as the space between two coaxial cylinders with a 0,05 mm radius di fference Because both filters are o f the same type, the type is not indicated twice as it was in Figure E.15 Figure E.16 — Example o f a cylindricity specification — Gaussian filter Figure E.17 shows an example of a roundness specification The specification element F (Fourier) indicates that the specification applies to a single harmonic (wavelength or UPR number) or a range o f harmonics The value indicates UPR as the identified harmonic, as the specification applies to a closed feature (a circle) The specification there fore applies to the 7th harmonic o f the feature Each individual filtered circum ferential line shall be contained in a tolerance zone defined as the space between two concentric circles with 0,02 mm radius difference NOTE Because UPR values are reverse o f wavelengths and the short wavelength is indicated first, the higher UPR value is indicated first for band-pass filters for closed features Figure E.17 — Example o f a roundness specification that applied to a single or a range o f harmonics An indication o f e.g “F7-” shall be used to indicate that the specification applies to a filtered feature that includes all harmonics longer than (lower UPR numbers) or equal to the indicated value, in this case all harmonics from UPR to UPR An indication o f e.g “F-7” shall be used to indicate that the specification applies to a filtered feature that includes all harmonics shorter than (higher UPR numbers) or equal to the indicated value, in this case all harmonics from UPR and higher An indication o f e.g “F7-2” shall be used to indicate that the specification applies to a filtered feature that includes the indicated range of harmonics, in this case all harmonics from UPR to UPR Figure E.18 shows an example of a position specification The specification element H indicates that the specification applies to the feature a fter the application o f a hull filter The value
