16、reword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technica
17、l committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part i
18、n the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval
19、 by at least 75% of the national bodies casting a vote. International Standard ISO/IEC 10641 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Sub-Committee SC 24, Computer graphics and image processing. Annex A and Annex B of this International Standard are for inform
20、ation only.ISO/IEC 10641:1993(E) BSI 02-2000 1 Introduction This International Standard addresses conformance testing of implementations of graphics standards. Conformance testing is the method used to determine the adherence or non-adherence of an implementation under test (IUT) to a standard. This
21、 International Standard specifies an approach for testing the conformance to computer graphics standards of products that claim to implement these standards. It addresses the conformance testing processes for all classes of graphics standards. This International Standard defines a general framework
22、of procedures and guidelines for conformance testing, together with definitions of terms and concepts. The framework given in this International Standard, together with the Test Requirements document for a particular graphics standard, provides a description of the procedures to be followed to achie
23、ve successful conformance testing of products for conformance to a particular graphics standard. The concept of conformance is central to every standard. The aims and benefits of a standard can be realized if there is a means of testing for conformance. The main reasons for introducing a document on
24、 conformance testing in the area of computer graphics are: To promote standards that are developed in a way such that products can be tested for conformance to the standards requirements; To promote that conformance is addressed in each standard; To promote test suites that are appropriately defined
25、 for testing products for conformance to all areas of the standard, and are of high quality; To promote test methods for similar standards that are developed in a consistent way; To promote conformance testing that is carried out in a consistent way throughout the international graphics community. U
26、sers of this International Standard include: Developers of graphics standards; Implementors of graphics standards; Developers of graphics test suites; Testing laboratories; Certification bodies; Accreditation bodies. Annex A and Annex B contain diagrams illustrating the relationships among the users
27、 of this International Standard and the information shared by them. 1 Scope This International Standard specifies a general framework for testing conformance to a computer graphics standard. The general framework described in this International Standard addresses the following six components: Confor
28、mance in the standard itself; Test Requirements document, defining what shall be tested for a computer graphics standard; Test Specifications document, addressing the test technique and the content of each test; Test method, defining the implementation of the Test Specification document, including t
29、he test software; Test procedures, defining the application of the test software, which consists of the procedures to be used in conformance testing; The establishment of test services. This International Standard is applicable to all standards within the scope of the subcommittee within ISO/IEC JTC
30、1 responsible for computer graphics and image processing. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are su
31、bject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
