equipped with open type traction batteries. If the REESS has been approved under Part II of this Regulation and installed in accordance with paragraph 5.2.1.1. this test can be omitted for the approval of the vehicle.
         5.4.2. The test shall be conducted following the method described in Annex 7 to the present Regulation. The hydrogen sampling and analysis shall be the ones prescribed. Other analysis methods can be approved if it is proven that they give equivalent results.
         5.4.3. During a normal charge procedure in the conditions given in Annex 7, hydrogen emissions shall be below 125 g during 5 h, or below 25 x t2 g during t2 (in h).
         5.4.4. During a charge carried out by a charger presenting a failure (conditions given in Annex 7), hydrogen emissions shall be below 42 g. Furthermore the charger shall limit this possible failure to 30 minutes.
         5.4.5. All the operations linked to the REESS charging shall be controlled automatically, included the stop for charging.
         5.4.6. It shall not be possible to take a manual control of the charging phases.
         5.4.7. Normal operations of connection and disconnection to the mains or power cuts shall not affect the control system of the charging phases.
         5.4.8. Important charging failures shall be permanently indicated. An important failure is a failure that can lead to a malfunction of the charger during charging later on.
         5.4.9. The manufacturer has to indicate in the owner's manual, the conformity of the vehicle to these requirements.
         5.4.10. The approval granted to a vehicle type relative to hydrogen emissions can be extended to different vehicle types belonging to the same family, in accordance with the definition of the family given in Annex 7, Appendix 2.
    6. Part II: Requirements of a Rechargeable Electrical Energy Storage System (REESS) with regard to its safety
         6.1. General
         The procedures prescribed in Annex 8 of this Regulation shall be applied.
         6.2. Vibration
         6.2.1. The test shall be conducted in accordance with Annex 8A to this Regulation.
         6.2.2. Acceptance criteria
         6.2.2.1. During the test, there shall be no evidence of:
              (a) Electrolyte leakage;
              (b) Rupture (applicable to high voltage REESS (s) only);
              (c) Fire;
              (d) Explosion.
         Evidence of electrolyte leakage shall be verified by visual inspection without disassembling any part of the tested-device.
         6.2.2.2. For a high voltage REESS, the isolation resistance measured after the test in accordance with Annex 4B to this Regulation shall not be less than 100 Ω/Volt.
         6.3. Thermal shock and cycling
         6.3.1. The test shall be conducted in accordance with Annex 8B to this Regulation.
         6.3.2. Acceptance criteria
         6.3.2.1. During the test, there shall be no evidence of:
              (a) Electrolyte leakage;
              (b) Rupture (applicable to high voltage REESS(s) only);
              (c)
