The main changes from the previous edition are: Clauses 1 and 3, 5.3, 6.1, 6.2, 7.3, 7.8, Tables 1 and 2, and the figures have been technically revised; Clause 8 and Annexes D and E have been added.ISO 14405 consists of the following parts, under the general title Geometrical product spe

32、be regarded as a general GPS standard (see ISO 14638). It influences chain links A to C of the chain of standards on size.The ISO GPS matrix model given in ISO 14638 gives an overview of the ISO GPS system of which this part of ISO 14405 is a part. The fundamental rules of ISO GPS given in ISO 8015

33、apply to this part of ISO 14405 and the default decision rules given in ISO 14253-1 apply to the specifications made in accordance with this part of ISO 14405, unless otherwise indicated.For more detailed information of the relation of this part of ISO 14405 to other standards and the GPS matrix mod

34、el, see Annex F.Produced workpieces exhibit deviations from the ideal geometric form. 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 w

35、orkpiece.The type of size can be indicated on the drawing by a specification modifier for controlling the feature definition.

36、llustrations included in this part of ISO 14405 are intended to illustrate the text and/or 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 illustration

38、lishes the default specification operator (see ISO 17450-2) for linear size and defines a number of special specification operators for linear size for features of size, e.g. “cylinder”, “sphere”, “torus,”1), “circle”, “two parallel opposite planes”, or “two parallel opposite straight lines”.It also

39、 defines the specification modifiers and the drawing indications for these linear sizes.This part of ISO 14405 covers the following linear sizes:a) local size: two-point size; spherical size; section size; portion size;b) global size: direct global linear size: least-squares size; maximum inscribed

40、size; minimum circumscribed size; minimax size; indirect global linear size;c) calculated size: circumference diameter; area diameter; volume diameter;1) A torus is a feature of size when its directrix diameter is fixed.INTERNATIONAL STANDARD ISO 14405-1:2016(E) ISO 2016 All rights reserved 1BS EN I

42、11); 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 13); an ISO tolerance class code in accordance with ISO 286-1 (e.g. 10 h6) (see Figure 12);with or without modifiers (see Tables 1 and 2).This part of ISO 14405 provides a set of

43、tools to express several types of size characteristic.
