Position the vehicle 1000 mm from the rigid stop. Release the vehicle and allow it to run freely down the slope(10°) , against a rigid stop made of steel and which is at least equal to the height of the axle of the wheels of the vehicle.
Carry out the test for a total of 10 times and check the displacement of the pram body or seat unit.
Then repeat the test with the vehicle facing in the reverse direction and check the displacement of the pram body or seat unit or car seat.
1.The angle of the slope can be adjustable : from 0-20 degree
