This International Standard specifies general requirements intended to  protect the rights, safety and well-being of human subjects,  ensure the scientific conduct of the clinical investigation and the credibility of the clinical investigation results,  define the responsibilities of the sponsor and principal investigator, and  assist sponsors, investigators, ethics committees, regulatory authorities and other bodies involved in the conformity assessment of medical devices. It does not apply to in vitro diagnostic medical devices. NOTE Standards developed by ISO/TC 194 are intended to be applied to medical devices.
