Annex Ab Table 1 Frequency and acceleration (gross mass of tested-device less than 12 kg) Frequency Hz Acceleration [m/s 2 ] 7 - 18 10 18 - approximately 50 gradually increased from 10 to 80 50 - 200 80 Table 2 Frequency and acceleration (gross mass of tested-device of 12 kg or more) Frequency Hz Acceleration [m/s 2 ] 7 - 18 10 18 - approximately 25 gradually increased from 10 to 20 25 - 200 20 1) The amplitude is then maintained at 0.8 mm (1.6 mm total excursion) and the frequency is increased until the maximum acceleration as described in table 1 or table 2 occurs. At the request of the manufacturer, a higher acceleration level as well as a higher maximum frequency maybe used. At the request of the manufacturer a vibration test profile determined by the vehicle-manufacturer, verified for the vehicle application and agreed with the Test Agency maybe used as a substitute for the frequency - acceleration correlation of Table 1 or Table 2. The approval of a REESS tested according to this condition shall be limited to approvals fora specific vehicle type. After the vibration, a standard cycle as described in Annex 8, Appendix 1 shall be conducted, if not inhibited by the tested-device. The test shall end with an observation period of 1 hat the ambient temperature conditions of the test environment.
