persons with exposed conductive parts.
         2.22. "Live parts" means the conductive part(s) intended to be electrically energized in normal use.
         2.23. "Luggage compartment" means the space in the vehicle for luggage accommodation, bounded by the roof, hood, floor, side walls, as well as by the barrier and enclosure provided for protecting the occupants from direct contact with live parts, being separated from the passenger compartment by the front bulkhead or the rear bulk head.
         2.24. "Manufacturer" means the person or body who is responsible to the approval authority for all aspects of the type approval process and for ensuring conformity of production. It is not essential that the person or body be directly involved in all stages of the construction of the vehicle, system or component which is the subject of the approval process.
         2.25. "On-board isolation resistance monitoring system" means the device which monitors the isolation resistance between the high voltage buses and the electrical chassis.
         2.26. "Open type traction battery" means a liquid type battery requiring refilling with water and generating hydrogen gas released to the atmosphere.
         2.27. "Passenger compartment" means the space for occupant accommodation, bounded by the roof, floor, side walls, doors, window glass, front bulkhead and rear bulkhead, or rear gate, as well as by the barriers and enclosures provided for protecting the occupants from direct contact with live parts.
         2.28. "Protection degree" means the protection provided by a barrier/enclosure related to the contact with live parts by a test probe, such as a test finger (IPXXB) or a test wire (IPXXD), as defined in Annex 3.
         2.29. "Rechargeable Electrical Energy Storage System (REESS)" means the rechargeable electrical energy storage system that provides electric energy for electric propulsion.
         The REESS may include subsystem(s) together with the necessary ancillary systems for physical support, thermal management, electronic control and enclosures.
         2.30. "Rupture" means opening(s) through the casing of any functional cell assembly created or enlarged by an event, large enough for a 12 mm diameter test finger (IPXXB) to penetrate and make contact with live parts (see Annex 3).
          2.31. "Service disconnect" means the device for deactivation of the electrical circuit when conducting checks and services of the  REESS, fuel cell stack, etc.
         2.32. "State of Charge (SOC)" means the available electrical charge in a tested-device expressed as a percentage of its rated capacity.
          2.33. "Solid insulator" means the insulating coating of wiring harnesses provided in order to cover and protect the live parts against direct contact from any direction of access; covers for insulating the live parts of connectors, and varnish or paint for the purpose of insulation.
         2.34. "Subsystem" means any functional assembly of REESS components.
         2.35. "Tested-device" means either the complete REESS or the
