Impact Tests on Crash Helmets for Motor Cyclists,

Abstract

Seven types of crash helmet were subjected to a series of impact tests as detailed in the current Australian Standard. Impact accelerations were usually less than 75% of the maximum permitted values, but second impacts near the front edge usually resulted in excessive accelerations. Four types of helmet, two with fibreglass shells and two with polycarbonate shells, were exposed to the weather for 15 to 17 months and one of the polycarbonate shells suffered degradation in its resistance to penetration.
