11、 is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be repre
12、sented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are
13、 drafted in accordance with the rules given in the ISOAEC 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
14、 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. IS0 shall not be held responsible for identifying any or all such patent rights. IS0 11 O 1 was prep
15、ared by Technical Committee ISO/TC 21 3, Dimensional and geometrical product specifications and verification. This second edition cancels and replaces the first edition (IS0 1101 :1983), which has been technically revised iv O IS0 2004 -All rights reserved IS0 11 O1 :2004(E) I n t ro d u ct i o n Th
16、is International Standard is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain links 1 and 2 of the chain of standards on form, orientation, location and run out, and chain link 1 of the chain of standards on da
17、tums. For more detailed information on the relation of this International Standard to the GPS matrix model, see Annex C. This International Standard represents the initial basis and describes the required fundamentals for geometrical tolerancing. Nevertheless, it is advisable to consult the separate
18、 standards referenced in Clause 2 and in Table 2 for more detailed information. For the presentation of lettering (proportions and dimensions), see IS0 3098-2. In the interest of uniformity, all figures in this International Standard have been drawn in first angle projection with dimensions and tole
19、rances in millimetres. It should be understood that third angle projection and other units of measurement could have been used equally well without prejudice to the principles established. The figures in this International Standard illustrate the text and are not intended to reflect an actual applic
20、ation. Consequently, the figures are not fully dimensioned and toleranced, showing only the relevant general principles. For a definitive presentation (proportions and dimensions) of the symbolization for geometrical tolerancing, see IS0 7083. Annex A of this International Standard has been provided
21、 for information only. It presents previous drawing indications that have been omitted here and are no longer used. It needs to be noted that the former use of the term “circularity” has been changed to the term “roundness” for reasons of consistency with other standards. Definitions of features are
22、 taken from IS0 14660-1 and IS0 14660-2, which provide new terms different from those used in previous edition of this International Standard. The former terms are indicated in the text following the new terms, between parentheses. For the purposes of this International Standard, the terms “axis” an
23、d “median plane” are used for derived features of perfect form, and the terms “median line” and “median surface” for derived features of imperfect form. Furthermore, the following line types have been used in the explanatory illustrations, .e. those representing non-technical drawings for which the
24、rules of IS0 128 (all parts) apply.

29、ions included in this International Standard are intended to illustrate the text andlor to provide examples of the related technical drawing specification; these illustrations are not fully dimensioned and toleranced, showing only the relevant general principles. As a consequence, the illustrations
30、are not a representation of a complete workpiece, and are not of a quality that is required for use in industry (in terms of full conformity with the standards prepared by ISOITC 10 and ISOITC 213), and as such are not suitable for projection for teaching purposes. This and future editions of IS0 11
31、01 will be revised to include improved illustrations whenever new amendments for IS0 1101 have reached the stage of publication. 1 Scope This International Standard contains basic information and gives requirements for the geometrical tolerancing of workpieces. It represents the initial basis and de
32、fines the fundamentals for geometrical tolerancing. NOTE Other International Standards referenced in Clause 2 and in Table 2 provide more detailed information on geometrical tolerancing. 2 Normative references The following referenced documents are indispensable for the application of this document.

42、ace limited by one or several geometrically perfect lines or surfaces, and characterized by a linear dimension, called a tolerance NOTE See also 4.4. 2 O IS0 2004 -All rights reserved IS0 11 O 1 :2004(E) 4 Basic concepts 4.1 Geometrical tolerances shall be specified in accordance with functional req
43、uirements. Manufacturing and inspection requirements can also influence geometrical tolerancing. NOTE Indicating geometrical tolerances on a drawing does not necessarily imply the use of any particular method of production, measurement or gauging. 4.2 A geometrical tolerance applied to a feature def
44、ines the tolerance zone within which that feature shall be con ta i ned . 4.3 A feature is a specific portion of the workpiece, such as a point, a line or a surface; these features can be integral features (e.g. the external surface of a cylinder) or derived (e.g. a median line or median surface). S
45、ee IS0 14660-1. 4.4 According to the characteristic to be toleranced and the manner in which it is dimensioned, the tolerance zone is one of the following: - the space within a circle; - the space between two concentric circles; - the space between two equidistant lines or two parallel straight line
46、s; - the space within a cylinder; - the space between two coaxial cylinders - the space between two equidistant surfaces or two parallel planes; - the space within a sphere. 4.5 Unless a more restrictive indication is required, for example by an explanatory note (see Figure 8), the toleranced featur
47、e may be of any form or orientation within this tolerance zone. 4.6 The tolerance applies to the whole extent of the considered feature unless otherwise specified as in Clauses 12 and 13. 4.7 Geometrical tolerances which are assigned to features related to a datum do not limit the form deviations of
48、 the datum feature itself. It may be necessary to specify tolerances of form for the datum feature(s).
