The standard will define the conformity evaluation tests suite for equipment to the EFC standard on """"Application interface definition for autonomous systems - Charging"""" (i.e. CEN ISO/TS 17575 - Part 1). 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). It will cover tests for the Back End equipment and for the Front End (as either a proxy or a smart client OBE) equipment.The approach and structure will be analogous to """"Conformity evaluation of on-board and road equipment to EN 15509"
