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:

1) Test Equipment System Certification

2) Jacket Certification

3) Pelvis Bottom Certification

4) Head Impact Pad Certification (TBD)

5) Repeat Test Equipment System Certification

6) Dummy Certification without Headrest (TBD)

7) Dummy Certification with Headrest (TBD)
