test road where the most representative wind conditions will be experienced.

              3.2.18. "Standard equipment" means the basic configuration of a vehicle which is equipped with all the features that are required under the regulatory acts of the Contracting Party including all features that are fitted without giving rise to any further specifications on configuration or equipment level.

              3.2.19. "Target road load" means the road load to be reproduced on the chassis dynamometer.

              3.2.20. "Target running resistance" means the running resistance to be reproduced.

              3.2.21. "Vehicle coastdown mode" means a system of operation enabling an accurate and repeatable determination of road load and an accurate dynamometer setting.

              3.2.22. "Wind correction" means correction of the effect of wind on road load based on input of the stationary or on-board anemometry.

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

              3.2.24. "Actual mass of the vehicle" means the mass in running order plus the mass of the fitted optional equipment to an individual vehicle.

              3.2.25. "Test mass of the vehicle" means the sum of the actual mass of the vehicle, 25 kg and the mass representative of the vehicle load.

              3.2.26. "Mass representative of the vehicle load" means x per cent of the maximum vehicle load where x is 15 per cent for category M vehicles and 28 per cent for category N vehicles.

              3.2.27. "Technically permissible maximum laden mass of the combination" (MC) means the maximum mass allocated to the combination of a motor vehicle and one or more trailers on the basis of its construction features and its design performances or the maximum mass allocated to the combination of a tractor unit and a semi-trailer.

              3.2.28. "n/v ratio" means the engine rotational speed divided by vehicle speed.

              3.2.29. "Single roller dynamometer" means a dynamometer where each wheel on a vehicle's axle is in contact with one roller.

              3.2.30. "Twin-roller dynamometer" means a dynamometer where each wheel on a vehicle's axle is in contact with two rollers.

              3.2.31. "Powered axle" means an axle of a vehicle which is able to deliver propulsion energy and/or recuperate energy, independent of whether that is only temporarily or permanently possible and/or selectable by the driver.

              3.2.32. "2WD dynamometer" means a dynamometer where only the wheels on one vehicle axle are in contact with the roller(s).

              3.2.33. "4WD dynamometer" means a dynamometer where all wheels on both vehicle axles are in contact with the rollers.

              3.2.34. "Dynamometer in 2WD operation" means a 2WD dynamometer, or a 4WD dynamometer which only simulates inertia and road load on the powered axle of the test vehicle and where the rotating wheels on the non-powered
