3、-1:2007 National foreword This Draft for Development is the UK implementation of CEN ISO/TS 12781-1:2007. It is identical to ISO/TS 12781-1:2003. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provision
4、al nature. It should be applied on this provisional basis, so that information and experience of its practical application can be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the international organization responsible fo
5、r its conversion to an international standard. A review of this publication will be initiated not later than 3 years after its publication by the international organization so that a decision can be taken on its status. Notification of the start of the review period will be made in an announcement i
6、n the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into an international Standard, to extend the life of the Technical Specification or to withdraw it. Comments sh
7、ould be sent to the Secretary of the responsible BSI Technical Committee at British Standards House, 389 Chiswick High Road, London W4 4AL. The UK participation in its preparation was entrusted to Technical Committee TDW/4, Technical product realization (TPR). A list of organizations represented on
8、this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. January 2009 9 Lic

23、, 02/02/2009 05:53, Uncontrolled Copy, (c) BSI ISO/TS 12781-1:2003(E) iv ISO 2003 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normall
24、y carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the
25、work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International 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 In
26、ternational Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is
27、 an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approv
28、ed by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS
29、 or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be tran
30、sformed into an International Standard or be withdrawn. 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 rights. ISO/TS 12781-1 was prepared by Technical Comm
31、ittee ISO/TC 213, Dimensional and geometrical product specifications and verification. ISO/TS 12781 consists of the following parts, under the general title Geometrical Product Specifications (GPS) Flatness: Part 1: Vocabulary and parameters of flatness Part 2: Specification operators DD CEN ISO/TS
32、12781-1:2007 Licensed Copy: London South Bank University, South Bank University, 02/02/2009 05:53, Uncontrolled Copy, (c) BSI ISO/TS 12781-1:2003(E) ISO 2003 All rights reserved v Introduction This part of ISO/TS 12781 is a geometrical product specification (GPS) Technical Specification and is to be
33、 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). For more detailed information on the relation of this part of ISO/TS 12781 to other standards and the GPS matrix model, see Annex C. This part o
34、f ISO/TS 12781 defines terms and concepts necessary for defining the specification operators according to ISO/TS 17450-2 for flatness of integral features. Extracting data will always involve applying a certain filtering process. An additional filtering of the extracted data may or may not be applie
35、d. 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 will influence the definition of flatness and the specification operators and, therefore, needs to be stated unambiguously. This part of ISO
36、/TS 12781 is not intended to disallow any means of measuring flatness.
