Dummy materials are becoming unavailable due to environmental and economic reasons. With regard to the WorldSID dummies, this is having an impact on the production of the iliac wings and skull. For the iliac wing, a new material has been identified and will undergo static and component level tests before a final verification with certification and biofidelity tests. Once all the testing is completed, several samples will be provided to the WorldSID task group to evaluate. With regard to the skull, a replacement material for the Ureol 100 has been identified and its material properties are being evaluated.

The question was raised on the type of evaluation is planned for the new material. With regard to a similar issue with the rib damping material, drop tests with the new and old ribs are being conducted, by the SAE group, at rates above and below the rates of crash tests and certification test to see if they give the same performance. Testing shows that the new material seems to provide higher damping. The results from these tests, plus sled tests, pendulum tests and drop tests, will be presented to the group upon completion. Additionally, Humanetics noted that there should not be a period when replacement parts are not available.

NHTSA is researching whether BRIC can be used as a complementary injury criterion to the HIC. BRICs have been developed for the ES-2 and the Hybrid III dummies. The same development procedure can be used to develop a BRIC for the WorldSID dummies. NHTSA requested that angular rate sensors (example shown in WS-5-13) be installed in the WorldSID dummies during testing to increase the data pool used to develop the WorldSID BRIC. Transport Canada noted that they have rotational data that can be sent to NHTSA.
