8 PERFORMING OF PEDESTRIAN IMPACT TESTS 8.1 General 8.1.1 Safety to personnel shall be a priority at all times 8.1.2 Ensure that all equipment used is in full working order, has been checked for safety and is in calibration where appropriate 8.2 Propulsion System 8.2.1 An air, spring or hydraulic gun will be used to propel the various body form impactors. 8.2.2 For the legform and the headform tests the impactors are required to be in free flight at the time of impact. 8.3 Fitting Replacement Parts to Vehicles 8.3.1 Careful note shall be taken before any testing is performed as to how any parts liable to need replacement are fitted to the vehicle structure. 8.3.2 Fitting of parts shall not increase or decrease the strength of the structure of the vehicle. 8.3.3 If significant repair work is required, this will be done at a manufacturer-approved dealer. 8.4 Photographic Record 8.4.1 A photographic record shall be kept of each test. 8.4.2 Before any testing has been conducted but after the vehicle is fully test prepared including all markings, the vehicle shall be photographed according to the following schedule. Note that these shall be the only pre-test photographs taken. 8.4.3 List of still photographs Amount of vehicle visible View Point Full vehicle Left side Full vehicle Right side Front third vehicle Left side Front third vehicle Right side Full vehicle Front Left half vehicle Front Right half vehicle Front Front third of vehicle Top Front third, right half of vehicle Top Front third, left half of vehicle Top Legform test points Front Upper legform test points Front Child head zone test points Top Adult head zone test points Top 8.4.4 Post-test photographs are detailed for each test type in the individual test procedures. 8.5 Testing Deployable Bonnets 8.5.1 Head test zones 8.5.1.1 Where bonnets are fully deployed and remain in the intended position before the smallest appropriate stature pedestrian head impact time (HIT), all testing will be carried out statically with the bonnet in the deployed state. 8.5.1.2 Where bonnets are NOT fully deployed prior to the smallest appropriate stature pedestrian, all testing will be performed dynamically for that stature. This also applies to systems that do not remain in a permanently deployed position. Version 7.0 March 2013 32
8.5.2 Static pedestrian tests 8.5.2.1 Static pedestrian tests will be performed in the normal way and according to the usual tolerances. 8.5.3 Dynamic pedestrian tests 8.5.3.1 Where dynamic tests are required, only a lateral impact tolerance of +/-10mm will be required. The headform shall be aimed at the grid point, the subsequent impact location on the bonnet top will then be determined by the timing of the bonnet deployment relative to the propulsion of the headform. 8.5.3.2 The vehicle manufacturer will be required to provide Euro NCAP with data from numerical simulations performed with the bonnet in the undeployed position. Simulations are to be conducted with a vehicle speed of 40km/h with all pedestrian statures that result in head contact to bonnet. Pedestrian models should be selected from the following statures, a 6 year old, 5th percentile female, 50th percentile male and 95th percentile male. The pedestrian position and stance to be used in the model is defined in Section 2.6.1.5. 8.5.3.3 From the simulations both head contact time and the wrap around distance that the head contacts the bonnet should be recorded. 8.5.3.4 A graph shall be plotted with a best fit straight line as shown in Figure 22. When a test point is selected, as the wrap distance will be known, the equivalent head contact time can be obtained from the graph that will be used in the dynamic test set up. Version 7.0 March 2013 Head Contact Time (ms) 138 128 118 108 98 88 78 68 58 6yr Old 5%tile 1000 1100 1200 1300 1400 1500 1600 1700 1800 1900 WRAP Distance (mm) Figure 22: WAD vs HIT 50%tile 8.5.3.5 The vehicle manufacturer must provide the test laboratory with all the necessary details of how to trigger the system, monitor trigger signals and replace spare parts. 8.5.4 Upper leg test zones 8.5.4.1 The test sites will be chosen with the bonnet in its un-deployed state. If bonnet deployment occurs prior to pedestrian contact with the Bonnet Leading Edge, creating an increased hazard such as higher BLE height and/or bumper lead, the Euro NCAP secretariat will give consideration to marking out the BLE in the deployed state. 8.5.4.2 Unless there is concern about additional hazards being created by the bonnet deploying prior or during pedestrian contact with the Bonnet Leading Edge, all upper legform to bonnet leading edge testing will be carried out with the bonnet in 33
