DIN EN ISO 12780-1:2014-04 EN ISO 12780-1:2011 (E) 3ISO 12780 consists of the following parts, under the general title Geometrical product sp

29、ecifications (GPS) Straightness: Part 1: Vocabulary and parameters of straightness Part 2: Specification operators Introduction This part of ISO 12780 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard (see ISO/TR 14638). It influences chain link 2

30、of the chain of standards on form of line independent of 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 rules of ISO/GPS given in ISO 8015 apply to this document and the default decision rules given in ISO

31、 14253-1 apply to specifications made in accordance with this document, unless otherwise indicated. For more detailed information of the relationship of this part of ISO 12780 to other standards and the GPS matrix model, see Annex C. This part of ISO 12780 defines terms and concepts necessary for de

32、fining the specification operators according to ISO 17450-2 for straightness of integral features. Extracting data always involves applying a certain filtering process. An additional filtering of the extracted data might or might not be applied. This additional filter can be a mean line filter (Gaus

33、sian, spline, wavelet, etc.) or a non-linear filter (e.g. morphological filter). The type of filtering influences the definition of straightness and the specification operators and, therefore, needs to be stated unambiguously. This part of ISO 12780 is not intended to disallow any means of measuring

34、 straightness. DIN EN ISO 12780-1:2014-04 EN ISO 12780-1:2011 (E) 4 1 Scope This part of ISO 12780 defines the terms and concepts related to straightness of individual integral features and covers complete straightness profiles only. NOTE Straightness of an extracted derived axis of a cylinder is de

35、fined in ISO 12180-1 and ISO 12180-2. 2 Normative references The following referenced documents are indispensable for the application of this document.
