NHTSA subsequently conducted six additional rigid barrier tests as part of a larger program to evaluate the use of a newer generation of test dummies in existing crash tests. Three additional rigid barrier tests were conducted with an updated seating procedure after minor changes were made to the THOR-50M test dummies. This report will extend the previous study to include the results from all 15 rigid barrier tests using a wider range of vehicle types. These tests also included a Hybrid III 5th percentile adult female (HIII-5F) ATD seated in the right front seat located in the mid track position. A second HIII-5F was seated in the right rear seat position. The RibEye Multi-Point Deflection Measurement System was installed into front and rear seated HIII-5Fs to provide additional measurements of the rib deflection.119
