Interpolate vertically between curves. 2. With bumper leads below 50mm - test as for 50mm. 3. With bumper leads above 350mm - test as for 350mm. 4. With bonnet leading edge heights above 1050 mm - test as for 1050mm. 5. With a required kinetic energy above 700J - test at 700J. 6. With a required kinetic energy below 200J - no test is required. 11.5.4 The total mass of the upper legform impactor includes those propulsion and guidance components which are effectively part of the impactor during the impact, including the extra weights. Calculate the value of the upper legform impactor mass from: Version 7.0 March 2013 550 600 650 700 750 800 850 900 950 1000 1050 Bonnet leading edge height (mm) 2E = V M 2 A B C D E Upper energy limit Lower energy limit 46
Version 7.0 March 2013 The upper legform impactor mass may be adjusted from the calculated value by up to ±10%, provided the required impact velocity is also changed using the above formula to maintain the same impactor kinetic energy. The influence of gravity on the velocity of the impactor must also be accounted for. 11.6 <strong>Test</strong> procedure - Pre-test 11.6.1 Ensure that the vehicle is fully test prepared as described in Section 1. 11.6.2 Ensure the vehicle is at the same ride heights as those recorded during marking up of the vehicle. 11.6.3 Ensure that the upper legform, the vehicle, the propulsion system and the data acquisition equipment has soaked in a temperature in the range of 16C to 24C for at least 2 hours prior to testing. 11.6.4 Fit a new piece of foam to the upper legform impactor from the certified sheet of foam. 11.6.5 Apply weights to the back of the upper legform impactor to bring the total mass up to that calculated in Section 11.5.4. Larger weights should first be applied and various smaller weights should then be added to achieve the correct weight. The upper legform impactor mass should be measured to an accuracy of better than ±1%, and if the measured value differs from the required value then the required velocity should be adjusted to compensate, as specified in 11.5.4. 11.6.6 The upper legform impactor shall be aligned such that the centre line of the propulsion system and the longitudinal axis of the impacting upper legform impactor are in the fore and aft vertical plane of the section of the vehicle to be tested. The tolerances to these directions are ±2°. At the time of first contact the impactor centre line shall be coincident with the bonnet leading edge reference line with a ±10mm tolerance, and laterally with the selected impact location with a tolerance of ±10mm. 11.6.7 Adjust the propulsion system to give the correct velocity and angle of incidence at the point of impact with the tolerance on the impact velocity being ±2%. The effect of gravity shall be taken into account when the impact velocity is obtained from measurements taken before the first point of contact. The velocity measuring device should be able to measure to an accuracy of at least 0.02m/s. The effect of gravity shall be taken into account when the impact velocity is obtained from measurements taken before the point of first contact. The tolerance on impact direction ±2°. 11.6.8 Roll the vehicle forwards to give the desired distance, so that the impactor strikes the vehicle after it has been accelerated to the test speed and so that any end stops on the guidance system do not interfere with its interaction with the vehicle. See Figure 29. 11.6.9 Fire the propulsion system. 47
