live parts.
         2.8. "Electrical chassis" means a set made of conductive parts electrically linked together, whose potential is taken as reference.
         2.9. "Electrical circuit" means an assembly of connected live parts which is designed to be electrically energized in normal operation.
         2.10. "Electric energy conversion system" means a system that generates and provides electric energy for electric propulsion.
         2.11. "Electric power train" means the electrical circuit which includes the traction motor(s), and may include the REESS, the electric energy conversion system, the electronic converters, the associated wiring harness and connectors, and the coupling system for charging the REESS.
         2.12. "Electronic converter" means a device capable of controlling and/or converting electric power for electric propulsion.
         2.13. "Enclosure" means the part enclosing the internal units and providing protection against direct contact from any direction of access.
         2.14. "Exposed conductive part" means the conductive part which can be touched under the provisions of the protection IPXXB, and which becomes electrically energized under isolation failure conditions. This includes parts under a cover that can be removed without using tools.
         2.15. "Explosion" means the sudden release of energy sufficient to cause pressure waves and/or projectiles that may cause structural and/or physical damage to the surrounding of the tested-device.
         2.16. "External electric power supply" means an alternating current (AC) or direct current (DC) electric power supply outside of the vehicle.
         2.17. "High Voltage" means the classification of an electric component or circuit, if its working voltage is > 60 V and ≤ 1500 V DC or > 30 V and ≤ 1000 V AC root mean square (rms).
         2.18. "Fire" means the emission of flames from a tested-device. Sparks and arcing shall not be considered as flames.
         2.19.  "Flammable electrolyte" means an electrolyte that contains substances classified as Class 3 "flammable liquid" under "UN Recommendations on the Transport of Dangerous Goods – Model Regulations (Revision 17 from June 2011), Volume I, Chapter 2.3"[1]
         2.20. "High voltage bus" means the electrical circuit, including the coupling system for charging the REESS that operates on high voltage.
         Where electrical circuits, that are galvanically connected to each other, are galvanically connected to the electrical chassis and the maximum voltage between any live part and the electrical chassis or any exposed conductive part is  30 V AC and  60 V DC, only the components or parts of the electric circuit that operate on high voltage are classified as a high voltage bus.
         2.21. "Indirect contact" means the contact of 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,
