This proposal updates the reference to UN R25 to specify compliance according to the 04 series of amendments (from the current reference to the 03 series of amendments). This change thus updates UN R80 to incorporate changes in impact-energy dissipation criteria made to UN R25 pursuant to changes allowing greater forward displacement of occupants under UN R16.
