Services, use forces derived from the data obtained from alternative crash test procedures, but these forces shall be equal to or greater than the forces that would result from using data in accordance with the regulations specified above.
         6.4.2.3. Acceptance criteria
         During the test there shall be no evidence of:
              (a) Fire;
              (b) Explosion;
              (c1) Electrolyte leakage if tested according to paragraph 6.4.1.1.:
            (i) In case of aqueous electrolyte REESS:
                  For a period from the impact until 60 minutes after the impact there shall be no electrolyte leakage from the REESS into the passenger compartment and no more than 7 per cent by volume of the REESS electrolyte with a maximum of 5.0 l leaked from the REESS to the outside of the passenger compartment. The leaked amount of electrolyte can be measured by the usual techniques of determination of liquid volumes after its collection. For containers containing stoddard, coloured coolant and electrolyte, the fluids shall be allowed to separate by specific gravity then measured.
            (ii) In case of non-aqueous electrolyte REESS:
                   For a period from the impact until 60 minutes after the impact, there shall be no liquid electrolyte leakage from the REESS into the passenger compartment, luggage compartment and no liquid electrolyte leakage to outside the vehicle. This requirement shall be verified by visual inspection without disassembling any part of the vehicle.
              (c2) Electrolyte leakage if tested according to paragraph 6.4.2.2.
              For a high voltage REESS, the isolation resistance of the Tested-Device shall ensure at least 100 Ω/Volt for the whole REESS measured in accordance with Annex 5A or Annex 5B of this Regulation or the protection degree IPXXB shall be fulfilled for the Tested-Device.
              If tested according to paragraph 6.4.2.2., the evidence of electrolyte leakage shall be verified by visual inspection without disassembling any part of the Tested-Device.
         6.5. Fire resistance
         This test is required for REESS containing flammable electrolyte.
         This test is not required when the REESS as installed in the vehicle, is mounted such that the lowest surface of the casing of the REESS is more than 1.5m above the ground. At the option of the manufacturer, this test may be performed where the of the REESS's lower surface is higher than 1.5 m above the ground. The test shall be carried out on one test sample.
         At the manufacturer´s choice the test may be performed as, either:
              (a) A vehicle based test in accordance with paragraph 6.5.1. of this Regulation, or
              (b) A component based test in accordance with paragraph 6.5.2. of this Regulation.
         6.5.1. Vehicle based test
         The test shall be conducted in accordance with Annex 9E paragraph 3.2.1. of this Regulation.
         The approval of a REESS tested according to this paragraph shall
