5.
Software-zero all transducer readings by averaging the part of the signal
before time zero and subtracting this from the transducer reading.
6.
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.
7.
Sum the potentiometer signals to derive the total head angle of the head
form relative to pendulum arm.
Requirements
1.
The impact velocity should be between 3.8 and 4.0 m/s.
2.
The pendulum velocity decrease should be as indicated in the table below.

To meet the requirements of the frontal neck certification test (see note below):
3.
The maximum head angle (first maximum) should be between 36.9 and 45.8
degrees.
The peak moment shall be between 22.6 and 28.0 Nm.
Lateral Neck Test
Set-up
1.
Assemble the complete neck, as described in section 4.3 with interface plate
033-2308. See
2.
Attach the IF-217 6 AXIS LOAD CELL and TE-2650-11 SPACER FLEXION HEAD
FORM
to the head form. Slide the head form over the neck and attach with
four M5 x 12 SHCS.
3.
Attach the neck to the pendulum interface plate (4 x M5). Place the (modified)
020-2015 (TE-2650-15) intermediate plate between the neck and pendulum
interface. Align the neck and the interface, making sure that lateral axis of
the neck is in the direction of movement of the pendulum arm (see Figure
31). Also, make sure that the bending direction of the neck in the
