5.
Integrate the pendulum acceleration to check the deceleration velocity of the
pendulum. The velocity of the arm must be calculated at a point 1657.4 mm
from the pendulum pivot point.
6.
Sum the potentiometer signals to derive the total head relative to pendulum
arm angle.
Requirements
1.
The impact velocity should be between 4.3 and 4.5 m/s.
2.
The pendulum velocity decrease should be as indicated in the table below:

To meet the requirements of the frontal lumbar spine certification test:
3.
The maximum head angle (first maximum) should be between 54.0 and 69.0
degrees.
This value should occur between 45 and 75 ms from the time-zero point.
4.
The minimum head angle (first minimum) should be between -33.0 and -
23.0 degrees.
This value should occur between 165 and 195 ms from the time-zero point.
Lateral Lumbar Spine Test
Set-up
1.
Slide the certification head form over the spine-thorax interface bracket.
2.
Attach the spine to the pendulum interface plate. Align the lumbar spine and
the interface, making sure that lateral axis of the head form is in the direction
of movement of the pendulum arm (see
). Also, make sure that the
bending direction of the neck in the certification is the same as the initial
bending direction experienced in the test the dummy is being certified for
(LHS or RHS).
