1 Scope This standard specifies electromagnetic compatibility requirements and methods of measurement of audio video apparatus on board This standard is applicable to audio video apparatus on board for various kind of motor vehicle. Note: This standard is applicable to audio or video function of multimedia apparatus on board. For equipment that do not have audio and video as their main function (such as GPS navigation system with DVD playing function), they are only available for their audio and video functions. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply to this standard, however parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition applies.
