The Technical Specification will define the conformity evaluation tests suite for equipment to the EFC standard on """"Application interface definition for autonomous systems - Context data"""" (i.e. CEN ISO/TS 17575 - Part 3). This part will contain the test suite structure and test purposes (""""the human readable part""""), and use the methodology for defining conformity tests as defined in the TTCN suite of standards (i.e. ISO/IEC 9646).
