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 be in accordance with the said Regulations. This requirement is deemed to be met if the vehicle equipped with electric power train operating on high voltage is approved in accordance with UN Regulation No. 94 (04 series of amendments or later) or UN Regulation No. 137 (02 series of amendments or later) for frontal impact and UN Regulation No. 95 (05 series of amendments or later) for lateral impact.
         The approval of a REESS tested under this paragraph shall be limited to the specific vehicle type.
         6.4.1.2. Component based test
         The test shall be conducted in accordance with Annex 9C to this Regulation.
         6.4.1.3. 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 6.4.1.2.
         After the vehicle based test (paragraph 6.4.1.1.), REESS shall remain attached to the vehicle by at least one component anchorage, bracket, or any structure that transfers loads from REESS to the vehicle structure, and REESS located outside the passenger compartment shall not enter the passenger compartment.
         After the component based test (paragraph 6.4.1.2.) the Tested-Device shall be retained by its mounting and its components shall remain inside its boundaries.
         For a high voltage REESS the isolation resistance of the Tested-Device shall ensure at least 100 Ω/Volt for the whole REESS measured after the test in accordance with Annex 5A or Annex 5B to this Regulation, or the protection degree IPXXB shall be
