This part of ISO10303 specifies the techniques for conformance testing and the means to facilitate the use of those techniques by the testing laboratory and the client. This part of ISO10303 specifies the roles of both the testing laboratory and the client during the conformance assessment process, the need to reach mutual agreements between them, and the requirements on each of them. 1.1 Coverage The following are within the scope of this part of ISO10303: general requirements on the testing laboratory and on the client that are applicable to the conformance assessment process; the exchange of technical and administrative information, including a protocol implementation conformance statement (PICS) and a protocol implementation extra information for testing (PIXIT); the process of negotiation between the testing laboratory and the client to reach an agreement on: the definition of the implementation under test (IUT); the abstract test method and abstract test suite to be used; the conditions under which conformance testing will be performed; requirements for the structure and content of the test report that document the results of the conformance testing. The following are outside the scope of this part of ISO10303: the resolution of technical issues between the client and the testing laboratory that arise during the conformance assessment process; the production of diagnostic information in addition to the conformance log and conformance test report; any aspects that are not specific to the conformance testing of implementations of ISO10303 application protocols; the certification and testing laboratory accreditation processes. NOTE - Information on requirements on the testing laboratory and the client with respect to certification are given in annexD. Roles of accreditation and certification organisations are given in annexD of ISO10303-31. 1.2 Applicability This part of ISO10303 applies to the conformance testing of any implementation of an ISO10303 application protocol. The application protocols for which abstract test suites are specified are defined in the ISO10303-200 series. The abstract test suites are specified in the ISO10303-300 series. Conformance testing of an implementation is based on the use of an abstract test suite together with an abstract test method in accordance with ISO10303-34. The testing laboratory is responsible for conducting the conformance testing of an implementation of ISO10303 at the request of a client. A testing laboratory may be any of the following: organisations developing or supplying implementations of ISO10303; NOTE1 - Referred to as implementors. organisations verifying implementations of ISO10303 for their own use; NOTE2 - Referred to as users. organisations who are independent of suppliers or users of implementations of ISO10303, and whose business is the testing of such implementations. NOTE3 - Referred to as testing laboratories. This part of ISO10303 applies equally to those testing laboratories that are affiliated to suppliers or procurers, and those that are independent of suppliers and procurers. Clients may be: implementors or suppliers of systems using ISO10303, who are applying for their implementations to be tested; organisations that procure those implementations; any other interested party. This part of ISO10303 applies equally to all three types of clients.
