If, due to the configuration of the test site, the values of the radii cannot be observed, the tests may be carried out on tracks with other radii (maximum deviation 525 %), provided that the speed is varied to obtain the transverse acceleration resulting from the radius and speed indicated in the table for the particular category of vehicle.
Circular test. The vehicle shall be driven into a circle with a transverse acceleration of 5 m/s2 and at a test speed of 80 km/h.
