39 and 53 ms.
    5.10.7. The maximum headform centre of gravity displacements in the lateral and vertical direction should be 104  7 mm and 33  7 mm respectively.
    5.10.8. The performance of the lumbar spine can be adjusted by changing the length of the spine.
    5.11. Abdomen
    5.11.1. The dummy is seated on a flat, horizontal, rigid surface with no back support.  The thorax is positioned vertically, while the arms and legs are positioned horizontally.
    5.11.2. The impactor is a pendulum of 23.5 -  0.0/+0.2 kg and 152  2 mm diameter.
    5.11.3. The pendulum is equipped with a horizontal arm rest impactor face of 1.0  0.01 kg.  The total mass of the impactor with the arm rest face is 24.5 -  0.0/+0.2 kg.  The rigid arm rest is 70  1 mm high, 150  1 mm wide and should be allowed to penetrate at least 60 mm into the abdomen.  The centreline of the pendulum coincides with the centre of the arm rest.
    5.11.4. The impactor is equipped with an accelerometer sensitive in the direction of impact and located on the impactor axis.
    5.11.5. The impactor should freely swing onto the abdomen of the dummy with an impact velocity of 6.3  0.1 m/s.
    5.11.6. The impact direction is perpendicular to the anterior-posterior axis of the dummy and the axis of the impactor is aligned with the centre of the middle force transducer.
    5.11.7. The peak force of the impactor, obtained from the impactor acceleration filtered using CFC 180 and multiplied by the impactor/armrest mass, should be between 9.5 and 11.1 kN, and occur between 9.8 and 11.4 ms.
    5.11.8. The force-time histories measured by the three abdominal force transducers must be summed and filtered using CFC 600.  The peak force of this sum should be between 5.9 and 7.9 kN.
    5.12. Pelvis
    5.12.1. The dummy is seated on a flat, horizontal, rigid surface with no back support.  The thorax is positioned vertically while the arms and legs are positioned horizontally.
    5.12.2. The impactor is a pendulum of 23.5 - 0.0/+0.2 kg and 152  2 mm diameter.
    5.12.3. The impactor is equipped with an accelerometer sensitive in the direction of impact and located on the impactor axis.
    5.12.4. The impactor should freely swing onto the pelvis of the dummy with an impact velocity of 4.3  0.1 m/s.
5.12.5. The impact direction is perpendicular to the anterior-posterior axis of the dummy and the axis of the impactor is aligned with the centre of the H-point foam cylinder.
    5.12.6. The peak force of the impactor, obtained from the impactor acceleration filtered using CFC 180 and multiplied by the impactor mass, should be between 4.4 and
