ISO 16850:2007 specifies a test method to simulate the child head impact of a child pedestrian to the bonnet top of passengers vehicles or some light truck vehicles, as defined in ISO 3833.

The purpose of this test method is to simulate frontal impact of a vehicle, laterally to a pedestrian.

The impact device to be used in this test method will be robust for a vehicle impact velocity of up to 11 m/s.

While the test method specified addresses the reduction of a child pedestrian head injury risk, it does not test for injuries to other regions of the pedestrian. The evaluation of injury risk to other pedestrian body regions is determined using other test methods.

This test method does not consider downward pitching of the vehicle due to pre impact braking.

This test method and the corresponding HIC measurement utilize a free flight head form impactor, and does not consider the kinematics of the pedestrian body as a whole, nor does it consider the subsequent post-impact kinematics and potential injury risk.
