Abstract:

Protective helmets with fiberglass or polycarbonate shells were exposed to the weather for three years and subjected to conventional and new rigidity tests. These indicated that 1 Exposure did not cause deterioration in performance. 2 There was a serious imbalance between the rigidity of the shell and the hardness of the liner. 3 Some current Standards encourage selection of a grade of shock absorbing liner that is too hard relative to the rigidity of the shell.
