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 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.
         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 UN Regulations Nos. 94 or 137 for frontal impact, and Annex 4 to Regulation No. 95 for side impact with the said Regulations. This requirement is deemed to be met if the vehicle equipped with the 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.
         6.4.2.1.2. Vehicle specific component test
         The test shall be conducted in accordance with Annex 9D of this Regulation.
         The crush force specified in paragraph 3.2.1. of Annex 9D may be replaced with the value declared by the vehicle manufacturer using the data obtained from either actual crash tests or its simulation as specified in Annex 3 of UN Regulations Nos. 94 or 137 in the direction
