Proposal to define the moment of intertia 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.

18. GRSP resumed consideration on a proposal tabled by the expert from CLEPA (GRSP-55-15), aimed at introducing provisions to define the moment of inertia of the luggage impact test. The expert from Japan reminded GRSP of his previous proposal (GRSP-54-20) to regulate only the lower limit of the moment of inertia of the test blocks and proposed further consultation with the expert from CLEPA. Finally, GRSP agreed to resume discussion at its December 2014 session and requested the secretariat to distribute GRSP-55-15 with an official symbol.

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.
