26、ntroductionThis part of ISO 2538 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain links1, 2 and 3 of the chain of standards on angle.The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/
27、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 ISO 14253-1 apply to specifications made in accordance with this document, unless otherwise indicated.For more detailed information on the re
28、lation of this part of ISO 2538 to other standards and to the GPS matrix model, see Annex A.In this part of ISO 2538, the figures illustrate the text only and should not be considered as design examples. For this reason, the figures are simplified and are not to scale.DIN EN ISO 2538-2:2015-01 EN IS

37、 ISO 2538-2:2015-01 EN ISO 2538-2:2014 (E) 75 Tolerancing of wedgesWedges can be toleranced (both size and sloped feature) in accordance with the methods given in Figures 5 to 10.The letter symbol t is used to define the width of the tolerance zone.NOTE 1 Alternative methods of tolerancing using onl
38、y dimensional specifications do not give adequate indication with regard to the shape of the surface. Consequently, when alternative methods are used geometrical specifications according to ISO 1101 have to be added if required for functional reasons (see ISO 14405-2).NOTE 2 Generally, in this stand
39、ard, to express a geometrical specification of location, the characteristic symbol of position is used. The characteristic symbol for profile of any surface can also be used with the same meaning. The position characteristic symbol immediately gives the information that the toleranced feature is a f
40、lat surface. The profile of any surface characteristic symbol does not immediately give the information that the toleranced feature is a flat surface, it is necessary to analyse the indications of the whole drawing or query the CAD model of the part.t A BABh1234t/2hta) Specification b) Interpretatio
