12、 2001 All rights reserved ISO 10303-34:2001(E) v 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 normally carried out through ISO technical committees. Each
13、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 work. ISO collaborates closely with the International
14、 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 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 ca
15、sting a vote. International Standard ISO 10303-34 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and integration, Subcommittee SC 4, Industrial data. This International Standard is organized as a series of parts, each published separately. The parts of ISO 10303 fall i
16、nto one of the following series: description methods, integrated resources, application interpreted constructs, application protocols, abstract test suites, implementation methods, and conformance testing. The series are described in ISO 10303-1. A complete list of parts of ISO 10303 is available fr
17、om the Internet:Annex A forms a normative part of this part of ISO 10303. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Attention is drawn to the possibility that some of the elements of this part of ISO 10303 may be the subject of patent r
18、ights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 2001 All rights reservedISO 10303-34:2001(E) vi Introduction ISO 10303 is an International Standard for the computer-interpretable representation and exchange of product data. The objective is to provide a ne
19、utral mechanism capable of describing product data throughout the life cycle of a product, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and archiving. Th
20、is part of ISO 10303 is a member of the conformance testing series. This part of ISO 10303 specifies the test methods used in the conformance testing of implementations which read and write 10303 exchange structures or share information with SDAI implementations based on a given ISO 10303 applicatio
21、n protocol.

22、This part of ISO 10303 specifies the abstract test methods for conformance testing of an implementation of an ISO 10303 Application Protocol (AP). The scope is limited to the following implementation methods: preprocessors that claim to generate 10303 schema instances represented as exchange structu
23、res as defined by ISO 10303-21; postprocessors that claim to accept and process 10303 schema instances represented as exchange structures as defined by ISO 10303-21; preprocessors that claim to generate 10303 schema instances and use the SDAI interface as defined in ISO 10303-22 to populate an SDAI
24、implementation with these schema instances; postprocessors that claim to accept 10303 schema instances and use the SDAI interface as defined in ISO 10303-22 to extract schema instances from an SDAI implementation. The following are within the scope of this part of ISO 10303: the conformance assessme
25、nt process undertaken to evaluate the conformity of an implementation of an ISO 10303 application protocol. The abstract test methods are independently applicable to implementation methods based on ISO 10303-21 and ISO 10303-22; the methods to be followed by the testing laboratory using executable t
26、est cases (ETC). The methods presented are abstract, that is, they are independent of the implementation under test (IUT). The method descriptions cover the different steps from abstract test case (ATC) selection to test case report production. The following is outside the scope of this part of ISO
27、10303: the generation of executable test cases from abstract test cases. This part of ISO 10303 does not include abstract test methods for conformance testing of application protocol independent implementations of the Standard Data Access Interface (SDAI) - ISO 10303-22. 2 Normative references The f

45、I Standard Data Acess Interface SUT System Under Test 4 Overview and assumptions Two abstract test methods are defined in this part of ISO 10303. The first provides for testing of implementations that generate exchange structures, i.e., preprocessors. The second provides for testing of implementatio
46、ns that interpret exchange structures, i.e., postprocessors. These methods are defined in clauses 5 and 6 respectively. Both abstract test methods apply also to applications that interface with SDAI implementations in a data sharing environment. General principles and an overall framework for confor
47、mance testing are provided in ISO 10303-31. Requirements on test laboratories are defined in ISO 10303-32. The methods for preparing, controlling, observing, and analyzing implementations during testing are defined in this part of ISO 10303. Specific abstract test cases associated with ISO 10303 app
48、lication protocols are defined in corresponding ISO 10303 abstract test suite standards. A description of abstract test suites concepts and the requirements on their use are defined in each 10303 abstract test suite. 4.1 Components of exchange structure test methods Exchange structure test methods a

These are the Implementation Under Test (IUT), the Test Engine, and the System Under Test Operator (SUT Operator), respectively.
