Transport Canada conducted a series of testing to compare the in-vehicle response of the WorldSID 5th female to the SIDIIs in various impact configurations. Results showed significant differences in deflection, independent of the crash configuration or struck side location. With the WorldSID, rib deflections did not exceed much more than 11 – 15 mm in the tests, even though there appeared to be clear loading of the thorax at that level. Additionally, the WorldSID injury measurements were much lower than the SIDIIs. Further testing is needed to isolate the mechanism contributing to the reduced chest deflection response. It was also noted that the introduction of multi-point sensing could aid in tracking fore-aft and vertical displacement.

In the discussion of the results, others observed similar issues and sometimes this can be attributed to the adjustment of the IR-TRACC, but it was pointed out that this may not explain the differences between the dummies. Humanetics stated that the WorldSID 5th female is more sensitive to oblique loading than the SIDIIs and recommended comparing injury risk using IARV instead. Additionally, it was noted that the effect of kinematic differences between the dummies and the inherent variability in crash testing should not be underestimated.
