Scope
This user’s manual covers the Hybrid III 6-year-old child test dummy, including changes specified in 49 CFR Part 572, Subpart N in the final rule dated December 9, 2010. It is intended for technicians who work with this device. It covers the construction and clothing, disassembly and reassembly, available instrumentation, external dimensions and segment masses, as well as certification and inspection test procedures. Appendix A contains guidelines for safe handling of instrumented dummies. Appendix B contains instructions for repairing dummy flesh. Appendix C includes procedures for adjusting the joints throughout the dummy.

Dummy Testing and Equipment Committee
The Dummy Testing Equipment Committee (DTEC) is a group of experts with experience in the area of certification and handling of Anthropomorphic Test Devices (ATD), more commonly known as crash test dummies, and equipment related to ATD. The DTEC seeks to standardize the use and certification of ATD so that test data are both repeatable and reproducible.
