scope:

This part of ISO/IEC 9646 specifies the requirements and gives guidance for the production of system-independent conformance test suites for one or more OSI Standards or CCITT Recommendations. In particular, it is applicable to the production of all conformance testing standard for OSI and ISDN two-party protocols, including all draft versions of such conformance testing standards. This part of ISO/IEC 9646 is applicable to the production of conformance test cases which check the conformance of an implementation to the relevant static and/or dynamic conformance requirements by controlling and observing protocol behaviour. The Abstract Test Methods included in this part of ISO/IEC 9646 are, in fact, capable of being used to specify any test case which can be expressed abstractly in terms of control and observation of Protocol Data Units and Abstract Service Primitives. Nevertheless, for some protocols, test cases may be needed which cannot be expressed in these terms. The specification of such test cases is outside the scope of this part of ISO/IEC 9646, although the test cases may themselves need to be included in a conformance testing standard.
