29、GPS standard (see ISO/TR 14638). In the general GPS matrix, it influences chain link 1 in the distance and radius chains of standards and chain links 1, 2 and 3 in the angle chain of standards. The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this documen
30、t is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise indicated. For dimensions other than linear sizes, the requirement is ambiguous w
31、hen applied to the real workpiece. It is the presence of form and angular deviations on all real workpieces that makes these requirements ambiguous, i.e. there is a specification ambiguity. It has to be realized that this specification ambiguity can only be avoided for features of size toleranced in
32、 accordance with ISO 14405-1. For all other dimensions, geometrical tolerancing should be used in order to control the specification ambiguity. For more detailed information on the relation of this part of ISO 14405 to other standards and to the GPS matrix model, see Annex B. 4DIN EN ISO 14405-2:201
33、2-03EN ISO 14405-2:2011 (E) 1 Scope This part of ISO 14405 illustrates the use of geometrical tolerancing for dimensions that are not linear sizes to avoid the ambiguity that the use of r tolerances on these dimensions causes. Both linear and angular dimensions, except size of features of size are c
34、overed. Dimensional tolerancing can be indicated by r tolerancing or geometrical tolerancing. The ambiguity caused by using r tolerances for dimensions other than linear sizes (for individual tolerances and general tolerances according to, e.g. ISO 2768-1 and ISO 8062-3) is explained in Annex A. NOT
35、E 1 The figures, as shown in this part of ISO 14405, merely illustrate the text and are not intended to reflect actual usage. The figures are consequently simplified to indicate only the relevant principles. NOTE 2 For indications of size tolerances, see the following: ISO 14405-1 for linear size; I
36、SO 2538 for wedges; ISO 3040 for cones. NOTE 3 The rules for geometrical tolerancing are given in ISO 1101. 2 Normative references The following referenced documents are indispensable for the application of this document.

47、les for indicating r tolerances given in ISO 14405-1 apply to this part of ISO 14405 and are the basis for tolerancing on mechanical engineering drawings. In all other cases, special rules apply.

Specification ambiguity can only be avoided for linear sizes toleranced in accordance with ISO 14405-1. In order to control specification ambiguity, geometrical tolerancing shall be used.
