27、This part of ISO 14405 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO 14638). In the general GPS matrix, it influences chain links “Symbols and indications”, “Feature requirements” and “Feature properties” of the size chain of standards

28、.The ISO/GPS Masterplan 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 apply to this part of ISO 14405 and the default decision rules given in ISO 14253-1 apply to specifications made in accorda

29、nce with this part of ISO 14405, unless otherwise indicated.For more detailed information on the relation of this part of ISO 14405 to other standards and to the GPS matrix model, see Annex D.

30、s (GPS) Dimensional tolerancing Part 3: Angular sizes1 ScopeThis part of ISO 14405 establishes the default specification operator for angular size and defines a number of special specification operators for features of angular size: cone (truncated, i.e. frustum, or not), wedge (truncated or not), t

31、wo opposite straight lines (intersection of a wedge/truncated wedge and a plane perpendicular to the intersection straight line of the two planes of the wedge/truncated wedge, intersection of a cone/frustum and a plane containing the axis of revolution of the cone/frustum). See Figure 1 and Figure 2

32、.This part of ISO 14405 also defines the specification modifiers and the drawing indications for these angular sizes.This part of ISO 14405 covers the following angular sizes: local angular size: angular size between two lines; portion angular size; global angular size: direct global angular size: l

33、east squares angular size; minimax angular size; rank order angular size/indirect global angular size: maximum angular size; minimum angular size; average angular size; range of angular sizes; mid-range angular size; median angular size; standard deviation of angular size.This part of ISO 14405 defi

34、nes the meaning of tolerances of angular sizes indicated as + and/or - limit deviations, e.g. 0/-0,5, or indicated with upper limit of size (ULS) and/or lower limit of size (LLS), e.g. 35 max. or 15 min., 34/36,INTERNATIONAL STANDARD ISO 14405-3:2016(E) ISO 2016 All rights reserved 1BS EN ISO 14405-
