NOTE 1—This test line drawing shows test lines on helmet rather than on headform and uses dimensional nomenclature R, S, T, U as in other drawings
(formerly a, b, c,.). The position of the lines on this drawing has not changed except that they are a bit more stringent because of the angle of projection
from the c/g, which is the center of the ball about which the headform pivots to align an impact site with the anvil.
