35、OTE Retention of voltage class B components, e.g. RESS, is not covered in this part of ISO 6469 because it is not relevant for electrical safety.5.2 Protection against electric shock5.2.1 GeneralAfter the crash test at least one of the criteria specified in 5.2.2 through 5.2.5 shall be met for each
36、voltage class B electric circuit. This includes all voltage class B electric circuits which are disconnected or electrically separated in post-crash situations. For different parts of a circuit, different criteria specified in 5.2.2 through 5.2.5 may apply.If the test is performed under the conditio
37、n that part(s) of the voltage class B electric circuits are not electrically energized because of specific crash test conditions different from normal operation, the protection against electric shock shall be proved by either 5.2.3 or 5.2.4 for the relevant part(s). Examples for such specific test c
38、onditions are as follows: fuel cell vehicle crash test performed with alternative fuel; crash test performed with energy sources disconnected prior to the crash test.NOTE Electronic switches can be used for disconnection.
