— preprocessors that claim to generate 10303 schema instances represented as exchange structures 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 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 conformance assessment 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 test 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 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.
