31、6610-29:2015(E)IntroductionThis part of ISO 16610 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain links 3 and 5 in the GPS matrix structure.The ISO/GPS Masterplan given in ISO 14638 gives an overview of the
32、 ISO/GPS system of which this part of ISO 16610 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of ISO 16610 and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this part of ISO 16610, unless otherwise indicated.For mor
33、e detailed information of the relation of this part of ISO 16610 to the GPS matrix model, see Annex E.This part of ISO 16610 develops the terminology and concepts for spline wavelets.vi ISO 2015 All rights reservedBS EN ISO 16610-29:2015Geometrical product specifications (GPS) Filtration Part 29: Li
