direction horizontally perpendicular to the direction of travel. These forces shall be agreed by the manufacturer together with the Technical Service.
         The manufacturers may, in agreement with the Technical 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) For a period from the impact until 30 minutes after the impact there shall be no electrolyte spillage from the REESS into the passenger compartment.
                  (ii) No more than 7 per cent by volume of the REESS electrolyte capacity shall spill from the REESS to the outside of the passenger compartment (for open type traction batteries a limitation to a maximum of 5 litres also applies).
              (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 4A or Annex 4B 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.
         To confirm compliance to (c1) of paragraph 6.4.2.3. an appropriate coating shall, if necessary, be applied to the physical protection (casing) in order to confirm if there is any electrolyte leakage from the REESS resulting from the impact test. Unless the manufacturer provides a means to differentiate between the leakage of different liquids, all liquid leakage shall be considered as the electrolyte.
         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 8E paragraph 3.2.1. of this Regulation.
         The approval of a REESS tested according to this paragraph shall be limited to
