Proposal to define the moment of inertia in the luggage-impact test as “0.3 ± 0.05 kgm2 (around all 3 principal axis of inertia of the luggage blocks)”. UN R17 presently lacks such a definition, resulting in variations in trajectory and behavior of the luggage cubes before and after impact. This proposal would also correct a reference to UN R25 to refer to the 04 series of amendments rather than to the 03 series of amendments.
