    6. Part II: Requirements of a Rechargeable Electrical Energy Storage System (REESS) with regard to its safety
         6.1. General
         The procedures prescribed in Annex 9 of this Regulation shall be applied.
         6.2. Vibration
         6.2.1. The test shall be conducted in accordance with Annex 9A to this Regulation.
         6.2.2. Acceptance criteria
         6.2.2.1. During the test, there shall be no evidence of:
              (a) Electrolyte leakage;
              (b) Rupture (applicable to high voltage REESS (s) only);
              (c) Venting (for REESS other than open-type traction battery);
              (d) Fire;
              (e) Explosion.
         The evidence of electrolyte leakage shall be verified by visual inspection without disassembling any part of the Tested-Device. An appropriate technique shall, if necessary, be used in order to confirm if there is any electrolyte leakage from the REESS resulting from the test. The evidence of venting shall be verified by visual inspection without disassembling any part of the Tested-Device.
         6.2.2.2. For a high voltage REESS, the isolation resistance measured after the test in accordance with Annex 5B to this Regulation shall not be less than 100 Ω/Volt.
         6.3. Thermal shock and cycling
         6.3.1. This test shall be conducted in accordance with Annex 9B to this Regulation.
         6.3.2. Acceptance criteria
         6.3.2.1. During the test, there shall be no evidence of:
              (a) Electrolyte leakage;
              (b) Rupture (applicable to high voltage REESS (s) only);
              (c) Venting (for REESS other than open-type traction battery);
              (d) Fire;
              (e) Explosion.
         The evidence of electrolyte leakage shall be verified by visual inspection without disassembling any part of the Tested-Device. An appropriate technique shall, if necessary, be used in order to confirm if there is any electrolyte leakage from the REESS resulting from the test. The evidence of venting shall be verified by visual inspection without disassembling any part of the Tested-Device.
         6.3.2.2. For a high voltage REESS, the isolation resistance measured after the test in accordance with Annex 5B to this Regulation shall not be less than 100 Ω/Volt.
         6.4. Mechanical impact
         6.4.1. Mechanical Shock
         At the manufacturer´s choice the test may be performed as, either
              (a) Vehicle based tests in accordance with paragraph 6.4.1.1. of this Regulation, or
              (b) Component based tests in accordance with paragraph 6.4.1.2. of this Regulation, or
              (c) Any combination of (a) and (b) above, for different direction of vehicle travel.
         6.4.1.1. Vehicle based test
         Compliance with the requirements of the acceptance criteria of paragraph 6.4.1.3. below may be demonstrated by REESS(s) installed in vehicles that have been subjected to vehicle crash tests in accordance with UN Regulation No. 94, Annex 3 or UN Regulation No. 137, Annex 3 for frontal impact, and UN Regulation No. 95, Annex 4 for side impact. The ambient temperature and the SOC shall
