DIN EN ISO 16610-21:2012-10

This International Standard ISO 16610-21:2011 has been prepared by Working Group ISO/TC 213/WG 15 "GPS extraction and filtration techniques", secretariat BSI (United Kingdom), with the collaboration of German experts and been adopted as EN ISO 16610-21:2012 by Technical Committee CEN/TC 290 "Dimensional and geometrical product specification and verification" (secretariat: AFNOR, France). This part of ISO 16610 develops the terminology and a concept of Gaussian filters. It has the transmission for the cut-off wavelength as 50 % since the short wave and long wave portions of surface profile are separated and can be reconstructed without altering the surface profile. This part of ISO 16610 is a geometrical product specification (GPS) standard and is to be regarded as a global GPS standard (see ISO/TR 14638). It influences the chain links 3 and 5 of all chains of standards. The masterplan given in ISO/TR 14638 gives an overview of the ISO/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 about the relation of this part of ISO 16610 to the GPS matrix model, see Annex E. The committee responsible for this standard is NA 152-03-03 AA "Oberflächen" ("Surfaces") at DIN.
