EN ISO 12181-1:2011 (E) DIN EN ISO 12181-1:2011-07 3 Introduction This part of ISO 12181 is a geometrical product specification (GPS) standard and is
28、 to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain link 2 of the chain of standards on form of a surface (independent of a datum). The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this document is a part. The fundamental rul
29、es 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 relationship of this part of ISO 12181 to other standards and the
30、 GPS matrix model, see Annex C. This part of ISO 12181 defines terms and concepts necessary for defining the specification operators according to ISO 17450-2 for roundness of integral features. Extracting data always involves applying a certain filtering process. An additional filtering of the extra
31、cted data might or might not be applied. This additional filter can be a mean line filter (Gaussian, spline, wavelet, etc.) or a non-linear filter (e.g. morphological filter). The type of filtering influences the actual specification operator and, consequently, the actual definition of roundness. Th
32、erefore, the type of filtering needs to be stated unambiguously. This part of ISO 12181 is not intended to disallow any means of measuring roundness. EN ISO 12181-1:2011 (E) DIN EN ISO 12181-1:2011-07 4 1 Scope This part of ISO 12181 defines the terms and concepts related to the roundness of individ
33、ual integral features and covers complete roundness profiles only. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced docu
