The test is carried out onto a brake tester or if this cannot be achieved for technical reasons, a road test takes place where a declaration recording instrument is used to establish the braking ratio which relates to the maximum authorized mass or in the case of semi-trailers, to the sum of the authorized axle loads.

During the brake tester testing we check: The total performance of the braking system. Braking effort on each wheel of the same axle (one-side braking). Fluctuation of brake force during a complete wheel revolution. Handbrake performance.

With the appropriate equipment (convergence meter, deviation meter), we test the alignment of steering wheels.

A photometer is used to define if the dimming and intensity of passing and driving lights are within the set limits.

By using an exhaust gas analyzer, we check if the emissions from vehicles powered either by gasoline or LPG exceed the limits the manufacturer sets. The exhaust fumes measured by the analyzer are Carbon oxide (CO), the Hydrocarbons (HC) as well as Lambda coefficient which is not a pollutant in vehicles bearing an advanced emission test system. By using an aethalometer we check if the smoke opacity of the exhaust fumes exceeds the level authorized by the established rates.
