ABSTRACT
Crash pulse data (acceleration vs. time) from NHTSA are usually presented graphically as part of the hardcopy test report. The data presentation reflects filtering according to the applicable test procedure, which, in turn, references SAE J211.1 The plots generally indicate what filter class was used to present the data. Sometimes, they do not indicate the minimum and maximum acceleration values. Sometimes, the plots have notations showing the minimum and maximum values, which may or may not reflect filtering. If the notations do not comport with the plotted curve, it is probable that the minimum and maximum reflect unfiltered rather than filtered values.
