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.
19. GRSP resumed consideration on a proposal tabled by the expert from CLEPA (ECE/TRANS/WP.29/GRSP/2014/19), introducing provisions to define the moment of inertia of the luggage impact test. GRSP adopted the proposal and requested the secretariat to submit the proposal to WP.29 and AC.1, for consideration and vote at their June 2015 sessions as draft Supplement 3 to the 08 series of amendments to UN Regulation No. 17.
