1 Introduction
The BioRID Dummy Certification Procedures are to insure proper dummy performance.
These procedures include multiple tests to verify system inputs and two tests to verify
dummy performance.
These include:
1.1 Test Equipment System Certification
1.1.1 This test gives confidence the energy transfer device (ETD), test equipment
system, and impact probe are going to provide consistent test inputs to the
Dummy Certification.
1.2 Jacket Certification Test
1.2.1 This test verifies the jacket material stiffness stays consistent through time.
1.3 Pelvis Bottom Certification Test
1.3.1 This test verifies the material inside the pelvis has not changed over time.
1.4 Head Impact Pad Certification for Headrest Test
1.4.1 To be defined
1.5 Dummy Certification without Headrest Test
1.5.1 To be defined - This test insures the dummy’s neck will provide consistent
test results. The test also provides evidence the damper, neck bumpers,
muscle substitute springs and cable, are working correctly as a system.
1.6 Dummy Certification with Headrest
1.6.1 To be defined.
A typical full dummy certification would follow these certification steps:

7.2.8 Attach the dummy (without lower torso and arms) to dummy mounting plate
on the test equipment system, section 2.5.
7.2.9 Remove the head (JOHN BELOW TO PROVIDE DIFFERENT WORDING)
7.2.10 Verify the lateral angle of the occipital condyle (OC) plate is less than
+/-0.5 degrees, see Figure ?. Use the test equipment system linear guide
as a zero reference. Adjust dummy if necessary.

7.2.16 Position impact probe, section 2.2, so the impact probe centerline is parallel
+/- 0.5 degrees to the line of action plane of the impact probe, see Figure 1.
7.2.17 Position the test equipment system, section 2.5, line of travel parallel to the
longitudinal centerline of the impact probe, see Figure 1.
7.2.18 Mount the impact probe, section 2.2, acceleration measurement device on the
end of impact probe opposite to the impact face with its sensitive axis in line
with the longitudinal axis of the impact probe.
7.2.19 Mount the test equipment system, section 2.5, acceleration measurement
device to the test equipment system so its sensitive axis is parallel to the
longitudinal centerline of the impact probe.
7.2.20 Attach ETD, section 2.3, to test equipment system, section 2.5.
7.2.20.1 ETD side to side centerline plane parallel +/- 0.5 degrees to the line
of action plane of the impact probe, see Figure 1.
7.2.20.2 ETD line of action centerline is to be 0mm +/- 3mm horizontally and
vertically with the impact probe centerline at the point of impact
when mounted to the test equipment system, see Figure 1.
7.2.21 While the impact probe, section 2.2, is in its neutral state, position the test
equipment system, section 2.5, so the ETD, section 2.3, is just touching the
impact probe face.
7.2.22 Level the head fore and aft to less than +/- 0.5 degrees using the Head
Leveling Tool.
7.2.23 Ensure the test equipment system, section 2.5, has at least 500 mm of
unrestricted travel.
7.2.24 Soak all hardware in a controlled environment at any temperature between
20.6°C - 22.2°C and a relative humidity between 10 and 70 percent for a
period of time no less than 4 hours prior to testing.

7.3 Dummy Certification without Headrest Test Procedures
7.3.1 Release the impact probe, section 2.2, so that it achieves a velocity between
4.7 m/s to 4.8 m/s
7.3.2 Within 2mm of the point of impact, the impact probe, section 2.2, should be
level within +/- 0.5 degrees.
7.3.3 Time zero of the test is defined as the time of contact between the impact
probe, section 2.2, and the ETD, section2.3, device.
7.3.4 Collect the impact probe, section 2.2, acceleration.
7.3.5 Collect the test equipment system, section 2.5, acceleration.
7.3.6 Collect the T1 acceleration.
7.3.7 Collect locations A, B, C and D values.
7.3.8 Collect the upper neck moment My values.
7.3.9 Wait at least 30 minutes between successive impacts on the same dummy.
