Proposal to reflect the size ranges used in UN R129, OICA suggests using the stature of 100 cm (which is approximately a child weighing 18 kg). This would be aligned with the requirement that non-integral ECRS are not allowed for children with a stature of less than 100 cm (6.1.3.3.) and also with the requirement for toxicity testing in 6.3.1.1 (para 6.3.1.1 does not apply to non-integral ECRS with a stature range of 100 cm or above).
42. The expert from OICA introduced GRSP-73-25-Rev.1, aimed at amending the provisions for the number of ISOFIX positions if a built-in CRS is installed in that position. He added that the provision would be adapted to height stature according to UN Regulation No. 129 instead of the superseded mass group of UN Regulation No. 44. GRSP adopted the proposal as reproduced in annex XI to the session report. The secretariat was requested to submit the proposal as draft Supplement 3 to the Original Version of UN Regulation No. 145, for consideration and vote at the November 2023 sessions of WP.29 and AC.1.
