Apparatus for Impact Testing of Shoulder Pads 6.3.5 Calculations Maximum acceleration The peak acceleration is calculated by measuring the perpendicular distance to the trace baseline from the midpoint of the trace at maximum excursion and multiplying by the sensitivity factor. The sensitivity factor is defined as g per division deflection of the trace. 6.3.6 Duration of Impulse Determine the duration of the pulse by measuring the total width of the trace along the 150g line in milliseconds. 7.
