Foreword Before the transfer of standard reference, QC/T 413-1999 Basic Technical Requirements for Automotive Electric Equipment referred to the Standard ZB T35001-1987. Therefore, the revision of this time is actually the major revision of this Standard after 15 years. The standard is modified with reference to relevant standards of Japan, Germany and France. This Standard supersedes QC/T 413-1999 Basic Technical Requirements for Automotive Electric Equipment.
