The 01 series of amendments to UN R129 amended the door panel geometry to create a small opening close to the seat bight. This change protected the panel from interaction with the anchorage of the adult seat belt on the test bench (added subsequently in the 02 series). Although Integral ISOFIX Enhanced Child Restraint Systems (ECRS) do not use the belt, these CRS were also required to use this new door panel geometry. This proposal amends the 02 series of amendments to require Integral ISOFIX ECRS to use the original door panel geometry with no opening (except during extensions of approvals in which the new panel geometry was used). The proposal ensures that ISOFIX ECRS designs cannot use the opening to mitigate loads to the ECRS and dummy.
32. The expert from CLEPA withdrew ECE/TRANS/WP.29/GRSP/2018/31 and introduced GRSP-64-42 to clarify that conformity of production (COP) testing should be conducted using the same requirements which were effective at the time of the initial approval or any later applicable extension. The expert from Italy suggested that a similar requirement could be handed over to other UN Regulations to ensure consistency of COP testing. GRSP adopted GRSP-64-42 as reproduced in Annex V to the session report. The secretariat was requested to submit GRSP-64-42 as part of (see paras. 29–31) draft Supplement 5 to the 02 series of amendments and as part of (see paras. 29–31) draft Supplement 2 to the 03 series of amendments to UN Regulation No. 129 for consideration and vote at the June 2019 sessions of WP.29 and AC.1.
