1 SCOPE

This document specifies the functional safety related activities and work products for the safety-related electrical and/or electronic (E/E) systems during the concept phase and at the system level, and the requirements for and methods of making functional safety audit and assessment, so as to check and verify the compliance of the development process and work products with the functional safety.

This document is applicable to the safety-related systems that include one or more E/E systems and that are installed in series production road vehicles, excluding mopeds.

This document is not applicable to the specific E/E systems in special purpose vehicles such as E/E system designed for drivers with disabilities.
