33. As per paragraph 16, the expert from the Netherlands on behalf of the Ad Hoc Group on CRS introduced ECE/TRANS/WP.29/GRSP/2023/13 and GRSP-73-18-Rev.2 on allowing the use of LTA. GRSP noted that the additional sentence in paragraph 6.6.4.1.2.1., that clarifies how ISOFIX ECRS should be dynamically tested, was removed from GRSP-73-18-Rev.2. This would allow the new 04 series of amendments to UN Regulation No. 129 proposed in GRSP-73-18-Rev.2 to focus on provisions for Enhanced Child Restraint Systems (ECRS) with lower tethers. GRSP agreed with the principle of the sentence on ISOFIX ECRS, to clarify that an ISOFIX ECRS that relies on the vehicle seat as the sole anti-rotation device must be dynamically tested on each vehicle body shell specified on the CRS fitting list. However, GRSP noted that another amendment of paragraph 6.6.4.1.2. had been proposed by the expert from CLEPA in GRSP-73-42, and so agreed to resume discussion at its December 2023 session. GRSP also adopted ECE/TRANS/WP.29/GRSP/2023/13 as amended by annex VIII to the session report. The secretariat was requested to submit the proposal as draft 04 Series of Amendments to UN Regulation No. 129 to the November 2023 sessions of WP.29 and AC.1. The secretariat was also requested to distribute GRSP-73-42 with an official symbol at its next session. GRSP requested its experts to provide comments on GRSP-73-42 to the expert from CLEPA.

34. The expert from the Netherlands, on behalf of the Technical Services Group, introduced ECE/TRANS/WP.29/GRSP/2023/11 and GRSP-73-14-Rev.1 amending it, to clarify the single belt route principle in paragraph 3.2.2. of the UN Regulation. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/11 as amended by annex VIII to the session report, and requested the secretariat to submit it as draft Supplement 10 to the 03 Series of Amendments and as part of (paragraph 33) the draft 04 series of amendments to UN Regulation No. 129 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

35. GRSP considered ECE/TRANS/WP.29/GRSP/2023/14 on prevention of green indicators suggesting a belt route outside the remit of the type-approval. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/14, as amended below, and requested the secretariat to submit the proposal as part of (paragraphs 33 and 34 above) draft Supplement 10 to the 03 series of amendments and to include it into (paragraphs 33 and 34) the draft 04 Series of Amendments to UN Regulation No. 129 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

The title, amend to read:
“Proposal for Supplement 10 to 03 Series of Amendments and 04 Series of Amendments to UN Regulation No. 129 (Enhanced Child Restraint Systems)” **

** Note by the secretariat: The change of the title was agreed with the author of the proposal to include the text of the draft Supplement 10 to the 03 Series of Amendments into the draft 04 Series of Amendments to UN Regulation No. 129.
