Confirm that the attenuator contains the minimum volume 200mm wide x 100mm high x 200mm long


Figure 1: Force-Displacement Curve (dynamic tests must show displacement during collision and after the point v=0 and until force becomes = 0)


Figure 2: Energy-Displacement Curve (dynamic tests must show displacement during collision and after v=0)


Energy Absorbed (J):

                                                 Figure5: The size of the impact attenuator

Length (fore/aft direction):       210     mm (>=200mm)
Width (lateral direction):          200      mm (>=200mm)
Height (vertical direction):       150       mm (>=100mm)
Attenuator is at least 200mm wide by 100mm high for at least 200mm: Yes
