INJURY CRITERIA CALCULATIONThis chapter describes the calculation for each injury criteria used within Euro NCAP,
including the filters that are applied to each channel used in these calculations. The
analysis software used by the Euro NCAP labs will follow these calculations in detail.
For all of the calculations and for all of the dummies used (except for the Q1.5 andQ3), only the loading phase of the crash is considered.
