The striker is allowed to fall freely from a height of 1000mm± 5mm measured
from the point, of the striker onto the crown of the helmet (within an area on the
fore/aft centre line ± 25mm) at two separate sites avoiding any damaged areas from
previous tests.
The helmet should be mounted onto the correct size headform with a soft insert in
the crown.
When the helmet is tested in either the low, ambient, or high temperature
conditions, contact shall not be made between the striker and the test block.
