The PIPER scalable child Human Body Model was recently released. It is scalable as a function of stature/age within the PIPER software. While several applications have been performed in frontal impact as new versions of the model were developed, no side impact applications have been reported up to now. The objectives of the current study were to investigate the usability of the PIPER child model and software for side impact through two applications related to the effect of anthropometric variations. In the first application, the pelvic region validation setup from Ouyang et al. (2003) was investigated using five subject specific models. The anthropometric variations were found to partially explain the experimental variability. In the second application, the extreme anthropometric range possibly represented by the Q3 dummy in the regulation R129 was studied. A large effect was also observed on the response in simplified side impact simulations. The results should be considered as preliminary considering some of the statistical and setup assumptions made to build the extreme models. However, the methodology that was developed could be used with different assumptions to refine the extreme models, and these could be use in the future to check the CRS dynamic behaviour not only for dummy dimensions but for the complete range of anthropometry a dummy is covering.
