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 4A or Annex 4B to this Regulation, or the protection degree IPXXB shall be fulfilled for the tested-device.
         For a REESS tested in accordance with paragraph 6.4.1.2., 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 6.4.1.3. 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.
         6.4.2. Mechanical integrity
         This test applies only to a REESS intended for installation in vehicles of categories M1 and N1.
         At the manufacturer's choice, the test may be performed as, either:
              (a) Vehicle based tests in accordance with paragraph 6.4.2.1. of this Regulation, or
              (b) Component based tests in accordance with paragraph 6.4.2.2. of this Regulation.
         6.4.2.1. Vehicle specific test
         At the manufacturer's choice, the test may be performed as either:
              (a) A vehicle based dynamic tests in accordance with paragraph 6.4.2.1.1. of this Regulation, or
              (b) A vehicle specific component test in accordance with paragraph 6.4.2.1.2. of this Regulation, or
              (c) Any combination of (a) and (b) above, for different directions of vehicle travel.
         When the REESS is mounted in a position which is between a line from the rear edge of the vehicle perpendicular to the centre line of the vehicle and 300 mm forward and parallel to this line, the manufacturer shall demonstrate the mechanical integrity performance of the REESS in the vehicle to the Technical Service.
         The approval of a REESS tested under this paragraph shall be limited to specific vehicle type.
         6.4.2.1.1. Vehicle based dynamic test
         Compliance with the requirements of the acceptance criteria of paragraph 6.4.2.3. below may be demonstrated by REESS(s) installed in vehicles that have been subjected to a vehicle crash test in accordance with the Annex 3 to Regulations Nos. 12 or 94 for frontal impact, and Annex 4 to Regulation No. 95 for side impact. The ambient temperature and the SOC shall be in accordance with the said Regulations.
         6.4.2.1.2. Vehicle specific component test
     The test shall be conducted in accordance with Annex 8D of this Regulation.
         The crush force replacing the prescribed force specified in paragraph 3.2.1. of Annex 8D shall be determined
