2. DETERMINATION OF THE ADHESION UTILIZATION (ε).

2.1. The adhesion utilized is defined as the quotient of the maximum braking rate with the anti-lock device in operation (Zmax) and the maximum braking rate with the anti-lock disconnected (Zm). Separate tests must be carried out on each wheel equipped with an anti-lock device.

2.2. Zmax is calculated on the on the basis of the average of the three tests, using the time taken for the speed of the vehicle to achieve the reductions in speed specified in 1.4.

2.3. The adhesion utilized is given by the formula
