22、l 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. Internation
23、al 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
24、 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 le
25、ast 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. ISO 14405-1 was prepared by Technical Committee ISO/TC

I
28、t influences chain links 1 to 3 of the chain of standards on size. The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this document is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rules given in
29、ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise indicated. For more detailed information of the relation of this part of ISO 14405 to other standards and the GPS matrix model, see Annex D. Produced workpieces exhibit deviations from the ideal geometric for
30、m. The real value of the dimension of a feature of size is dependent on the form deviations and on the specific type of size applied. The type of size to be applied to a feature of size depends on the function of the workpiece. The type of size can be indicated on the drawing by a specification modi
31、fier for controlling the feature definition and evaluation method to be used.

33、cial specification operators for linear size for feature of size types “cylinder” and “two parallel opposite planes”. It also defines the specification modifiers and the drawing indications for these linear sizes. This part of ISO 14405 covers the following linear sizes: local size; two-point size;
34、spherical size; section size; portion size; global size; direct global linear size; least-squares size; maximum inscribed size; minimum circumscribed size; indirect global linear size; calculated size; circumference diameter; area diameter; volume diameter; rank-order size; maximum size; minimum siz
35、e; average size; median size; Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 07/06/2011 08:16, Uncontrolled Copy, (c) BSIBS EN ISO 14405-1:2010ISO 14405-1:2010(E) 2 ISO 2010 All rights reserved mid-range size; range size. This part of ISO 14405 defines tolerances of linear sizes when there i
36、s: a + and/or limit deviation (e.g. 0/0,019) (see Figure 9); an upper limit of size (ULS) and/or lower limit of size (LLS) (e.g. 15,2 max., 12 min. or 30,2/30,181) (see Figure 11); an ISO tolerance class code in accordance with ISO 286-1 (e.g. 10 h6) (see Figure 10) with or without modifiers (see Ta
37、bles 1 and 2). This part of ISO 14405 provides a set of tools to express several types of size characteristic. It does not present any information on the relationship between a function or a use and a size characteristic. 2 Normative references The following referenced documents are indispensable fo
