Data Processing
1.
All three accelerations should be filtered at CFC1000.
2.
Determine the resultant head acceleration.
Requirement
1.
The maximum resultant head acceleration response should be between 95 and 125
g’s.
2.
The acceleration in Y-direction should be between -10 and 10 g’s.
Lateral Impact Head Certification
Test Procedure
1.
The head is suspended above a rigid, heavy, metal plate. The properties of this plate
are described in section 7.2 under the heading “Head Drop Table” of this manual.
Users are advised to use a thin wire basket (TE-2651) to position the head. The net
has a piece of steel attached to it, which allows the use of a magnet to keep the head
in place. The net allows easy adjustment of the head in any orientation.
2.
Position the head in such a way, that the mid-sagittal plane has an angle of 35 ± 2
degrees with the horizontal axis, and the anterior-posterior axis is horizontal, ± 1
degrees. This corresponds to an angle between the horizontal plane and the head
base plane of 55 ± 2 degrees, see Figure 28. When released, the head should impact
the surface with the side of its head.
3.
The lowest point of the head should be 130 ± 1 mm above the impact surface.
4.
Release the head.
5.
The minimum time interval to observe between tests on the head is 30 minutes.
