The objective of this 1942 report was to investigate the possibility of a nondestructive magnetic test for helmets, and to investigate the relation of other physical properties of helmet stock to the ballistic performance of helmets. It was concluded that it is not possible to devise a magnetic test which will distinguish in all cases between helmets which have different ballistic properties.
