Division 3.6

Inertia braking systems may incorporate overload protectors. They shall not be activated at a force of less than D_op = 1,2 · D* (when fitted at the control device) or at a force of less than P_op = 1,2 · P* or at a pressure of less than pop = 1,2 · p* (when fitted at the brake) where the force P* or the pressure p* corresponds to a braking force of B* = 0,5 · g · G_Bo (in the case of Classes C2 and C3 vehicles) and B* = 0,35 · g · G_Bo (in the case of Class C1 vehicles).
