18、this International Standard is to help reduce pedestrian head injuries by providing a standardized test method which will allow different test organizations to use the results from pedestrian impact tests conducted by other organizations. The test method specified applies to adults, but it is antici

19、pated that biomechanical data for children will later be studied in order to determine the potential for child pedestrian protection. ISO 2016 All rights reserved vBS ISO 14513:2016BS ISO 14513:2016Road vehicles Pedestrian protection Head impact test method1 ScopeThis International Standard specifie

20、s a test method to simulate the head impact of an adult pedestrian to the bonnet top of passenger vehicles or light truck vehicles of up to 3,5 t (GVM), as defined in ISO 3833. The impact device to be used in this test method will be robust for a vehicle impact velocity of up to 11 m/s. The test met

21、hod specified addresses the reduction of an adult 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 to be determined using other test methods. This test method does not consider downward pi

22、tching of the vehicle due to pre-impact braking. This test method and the corresponding HIC measurement utilizes 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 ri

23、sk.NOTE The test method covers an adult pedestrian head in a simulated impact with a motorized road vehicle. Research suggests vehicle safety improvements in vehicle derived from such pedestrian impact tests may be beneficial also to bicyclists in vehicle front impact.2 Normative referencesThe follo
