Table 2:

Pendulum impact testing locations. Measurements of Y and Z-position are relative to the basic plane of the NOCSAE headform. Positive rotation in the Y-axis is away from the pendulum, and positive rotation in the Z-axis is clockwise. The X-position is set such that the helmet contacts the impactor face when the pendulum arm is in a neutral vertical position for each location.

Location	Y (cm)	Z (cm)	Rotation Y (deg)	Rotation Z (deg)
Front	0	+5.2	−20°	0°
Front Boss	0	+2.2	−25°	+67.5°
Side	−4	+5.7	−5°	−100°
Back	0	+3.7	0°	−180°
