              3.3.7. "Power-to-test-mass-ratio" corresponds to the ratio of the rated engine power of the internal combustion engine over the test mass of the tested vehicle as defined in paragraph 8.3.1.

              3.3.8. "Power-to-mass-ratio" is the ratio of rated power to the mass in running order.

              3.3.9. "Rated engine power (Prated)" means maximum net power of the engine or motor in kW as per the requirements of UN Regulation No. 85.

              3.3.10. "Technically permissible maximum laden mass" means the maximum mass allocated to a vehicle on the basis of its construction features and its design performances.

              Mass definitions

         (1)        means the mass of the vehicle, with its fuel tank(s) filled to at least 90 per cent of its or their capacity/capacities, including the mass of the driver, fuel and liquids, fitted with the standard equipment in accordance with the manufacturer's specifications and, when they are fitted, the mass of the bodywork, the cabin, the coupling and the spare wheel(s) as well as the tools.
         (2)        means all the features not included in the standard equipment which are fitted to a vehicle under the responsibility of the manufacturer, and that can be ordered by the customer.
