ISO/TR9790 has been in existence for some years for evaluating the biofidelity of side impact ATDs (dummies) (ISO/TR 9790, 1999). NHTSA recently generated a new method for creating biofidelity corridors. The method was different from the ISO method, by incorporating statistics and the time relationships into the evaluation equation and automating the process (Maltese et al., 2002). Although both the ISO and NHTSA methods exhibit a number of strengths, they also have weaknesses. This paper attempts to build on these two methods to develop an ATD assessment method which offers added objectivity and is based on a statistical process. Improvements were explored in several key areas to address the existing numeric issues (Hsu et al., 2005). This process bases itself on the statistical correlations between the post-mortem human subject (PMHS) data. Detailed validation of the scheme is performed using PMHSs as “pseudo dummies”. A simple formula is proposed for ranking the biofidelity of the dummy, resulting in a score from 0-10, with 10 being the best.
