(Normative)
Test method for braking performance
A.1 Test method for braking performance in road test

Put the transmission in neutral, when the tested tractor increases to beyond the specified initial speed, along the centerline of the test lane; when it slides to the specified initial speed, the maximum operating force of the brake pedal shall not exceed 600 N, the maximum operating force of the brake handle shall not exceed 400 N; at this time, park the tractor, by pressing the brake suddenly.
A.1.3 Measure the braking distance of the tractor with a speedometer, fifth wheel meter or other test methods.
A.2 Test method for bench test braking performance
A.2.1 Inspection by a drum brake test bench
a) The surface of the drum of the brake test bench shall be dry and free from loose substances and oil stains. The driver drives the tractor onto the drum; corrects the position; starts the drum; applies the brakes. Measure the parameter values required in Table 3 in 9.4.2; record whether the wheels are locked.
b) When measuring braking, in order to obtain sufficient adhesion to avoid wheel locking, it is allowed to add enough additional mass to the tractor OR apply a force equivalent to the additional mass (additional mass or force is not included in the axle load). It may also take measures, to prevent the tractor from moving (such as adding triangular pads or towing, etc.).
c) When the above method is adopted, if the wheel still locks and slips on the drum OR the whole machine rolls backward with the drum, whilst the braking force still does not meet the qualified requirements, the road test method can be used for inspection.
A.2.2 Inspection by a flat-plate brake test bench
a) The flat surface of the brake test bench shall be dry AND free from loose No.1 Amendment sheet to national standard GB 16151.1-2008
