GRSP agreed to resume on a proposal of limit values on the chest vertical acceleration and neck loads of Q-dummies during the dynamic testing of Enhanced Child Restraint Systems (ECRS) tabled by the expert from CLEPA.

GRSP also agreed to resume on a proposal prepared by the expert from Spain, on behalf of the Technical Services Group (TSG) on UN Regulation No. 129, to clarify the head containment assessment for side impact testing (ECE/TRANS/WP.29/GRSP/2021/7).

GRSP-70-05 | UN R129: Proposal for Supplement 7 to the 03 series of amendments Proposal to clarify the head containment assessment for side impact testing.

Moreover, GRSP will consider a proposal tabled by the expert from CLEPA (ECE/TRANS/WP.29/GRSP/2021/26) amending the existing support leg volume to improve the compatibility between the support leg volume and the Child Restraint Fixtures used for assessing the external dimensions of an ECRS.
