ROAD TEST FOR COMFORT EVALUATION

Check 44A

- Carry out a road test on traffic free roads in safe conditions following the highway code.

- Before proceeding with the test, check the inflation pressure of the two vehicles, restoring the values to the correct ones if they are found to be incorrect.

- Also check the conditions of the wheel rims making sure they are not distorted or broken, replacing them if any faults are found.

- Carry out the test on an uneven road surface, at a speed of 40 km/h to check the capacity of the suspension to absorb the stresses produced by small imperfections (suspension damping) with the consesquent acoustic repercussions inside the passenger compartment.

- Check the capacity of the suspension to absorb the stresses produced by large imperfections and the consequent acoustic repercussions inside the passenger compartment, carry out the road test at a speed of 40 km/h over a route that has a series of pot-holes.

- Check the rapid damping of any pitching produced by the irregularities in the road surface, carrying out the test at a speed of 50 km/h on a straight road with suitably spaced humps and holes.
