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.
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.
18. The expert from CLEPA introduced GRSP-54-04, aimed at introducing provisions to define the moment of inertia of the luggage impact test. The expert from Japan introduced GRSP-54-20 proposing to regulate only the lower limit of the moment of inertia of the test blocks. Following the discussion, GRSP agreed to resume discussion at its May 2014 session on the basis of a revised proposal voluntarily prepared by the expert from CLEPA.
