19、tion for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established

20、has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. In

21、ternational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publi

22、cation as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent r

23、ights. ISO 12180-1 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical product specifications and verification. This first edition of ISO 12180-1 cancels and replaces ISO/TS 12180-1:2003, which has been technically revised. ISO 12180 consists of the following parts, under the

24、 general title Geometrical product specifications (GPS) Cylindricity: Part 1: Vocabulary and parameters of cylindrical form Part 2: Specification operators BS EN ISO 12180-1:2011ISO 12180-1:2011(E) ISO 2011 All rights reserved vIntroduction This part of ISO 12180 is a geometrical product specificati

25、on (GPS) standard and is 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 part of ISO 121

26、80 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of ISO 12180 and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this part of ISO 12180, unless otherwise indicated. For more detailed information on the relationship o

27、f this part of ISO 12180 to other standards and the GPS matrix model, see Annex D. This part of ISO 12180 defines terms and concepts necessary for defining the specification operators according to ISO 17450-2 for cylindricity of integral features. Extracting data always involves applying a certain f

28、iltering process. An additional filtering of the extracted 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 definition of cylindricity and th

29、e specification operators and, therefore, needs to be stated unambiguously. This part of ISO 12180 is not intended to disallow any means of measuring cylindricity.
