by thermal propagation which is triggered by an internal short circuit leading to a single cell thermal runaway such as fire, explosion or smoke. This requirement is deemed to be satisfied if the thermal propagation does not lead to a hazardous situation for the vehicle occupants. REESS or vehicle 'Manufacturer' shall include the following documentation explaining safety performance of the system level or
         sub-system level of the vehicle within its Supporting Information:
6.12.                                For paragraph 6.15.2 of Appendix A read:
         The REESS or vehicle system shall have functions or characteristics in the cell or REESS intended to protect vehicle occupants (as described in paragraph 6.15.) in conditions caused by thermal propagation which is triggered by an internal short circuit leading to a single cell thermal runaway. REESS or vehicle 'Manufacturers' shall include the following documentation explaining safety performance of the system level or
         sub-system level of the vehicle in its Supporting Information:
6.13.                                In Annex 7A of Appendix A, omit "testing authority", substitute "Approved Testing Facility".
6.14.                                Category MA, MB, MC and NA vehicles may as an alternative to the requirements in paragraph 4.1 of Annex 8 in Appendix A, demonstrate the chassis dynamometer meets the requirements of the Vehicle Standard (Australian Design Rule 79/03 – Emission Control for Light Vehicles) 2011.
6.15.                                In paragraph 3.5 of Appendix 1 in Annex 8 of Appendix A, omit "technical service", substitute "Approved Testing Facility".
6.16.                                For paragraph 3.2 of Annex 9A in Appendix A read:

         Test procedures

         The Tested-Devices shall be subjected to a vibration having a sinusoidal waveform with a logarithmic sweep between 7 Hz and 50 Hz and back to 7 Hz traversed in 15 minutes. This cycle shall be repeated 12 times for a total of 3 hours in the vertical direction of the mounting orientation of the REESS as specified by the 'Manufacturer'.

         The correlation between frequency and acceleration shall be as shown in Table 1:

       Table 1

       Frequency and acceleration

Frequency (Hz)  Acceleration (m/s2)
7 - 18          10

18 - 30         gradually reduced from 10 to 2

30 - 50         2

         Alternatively, a higher acceleration level as well as a higher maximum frequency may be used.

         A vibration test profile determined by the vehicle 'Manufacturer', verified for the vehicle application may be used as a substitute for the frequency - acceleration correlation of Table 1 where this profile is shown to be more representative of the vehicle type.

         The approval of a REESS tested according to this condition shall be limited to the installation for a specific vehicle type.

         After the vibration, a standard cycle as described in Annex 9, Appendix 1 shall be conducted, if not inhibited by the Tested-Device.

The test shall end with an
