Industrial safety helmets

Raymond

Last Update 4 years ago

This standard goes back over 50 years and testing is only carried out to the top of the helmet. A 49J impact only to the crown of the helmet is required for shock absorption and a penetration test with a 3kg conical striker from 1m. 


There are no side, front, or rear impact requirements in this standard only a lateral rigidity test, which is a slow, progressive force loading followed by measurement of any deformation.
