16. The expert from the Netherlands presented the status report of the Ad Hoc Group on CRS (GRSP-73-15) as an introduction to GRSP-73-16-Rev.2 (superseding ECE/TRANS/WP.29/GRSP/2023/9), which allows the use of Lower Tether Anchorages (LTA) as anti-rotation devices. He added that the proposal would not mandate the use of LTA, but would ensure that use be unambiguous, and that users be informed correctly. He also explained that the proposal would be accompanied by parallel proposals to UN Regulations Nos. 129 and 145. The expert from OICA introduced GRSP-73-24 to provide consistency on transitional provisions with other proposals of amendments to the UN Regulation. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/9, as amended by annex III to the session report. GRSP requested the secretariat to submit the proposal as the draft 09 Series of Amendments to UN Regulation No. 16 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

19. The expert from the Republic of Korea introduced the status report (GRSP-73-43) of the Ad Hoc Group on Safety-Belt Reminders (SBR). He informed GRSP that the Group agreed to clarify and resolve three SBR issues introduced at the seventy-second session of GRSP (GRSP-72-13). He concluded that the Group planned to convene virtually at the end of May to seek basis for a proposal for discussion at the December 2023 session of GRSP. The expert from France introduced ECE/TRANS/WP.29/GRSP/2023/17, to clarify: (a) how to assess SBR connection in the case of removable seats and (b) test procedure of SBR. The expert from OICA reiterated that GRSP-73-24 also amends ECE/TRANS/WP.29/GRSP/2023/17. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/17 as amended by annex III to the session report. GRSP requested the secretariat to submit the proposal as part of the draft 09 Series of Amendments (paragraphs 17 to 19) to UN Regulation No. 16 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

16. GRSP resumed discussion on a proposal (ECE/TRANS/WP.29/GRSP/2022/13) tabled by the expert from France on clarifying the assessment of the connection of the Safety-Belt Reminder (SBR) system in the case of removable seats. GRSP also noted a presentation (GRSP-72-23) to introduce a proposal for a new series of amendments (GRSP-72-22). The expert from France explained that the proposal would clarify the requirements for SBR systems on test procedure (first- and second-level warning), visual warning and requirements for SBR in the rear seat row(s).

17. GRSP agreed to resume discussion at its May 2023 session on a revised document combining GRSP-72-22 and ECE/TRANS/WP.29/GRSP/2022/13, as a new series of amendments. GRSP requested its experts to provide feedback on GRSP-72-22 and ECE/TRANS/WP.29/GRSP/2022/13 to the expert from France before the deadline for submission of official documents for the May 2023 session.

20. The expert from Germany introduced ECE/TRANS/WP.29/GRSP/2022/20 to ensure that only safe head restraints would be fitted to seats of any seating position in all vehicle categories that were in the scope. He introduced ECE/TRANS/WP.29/GRSP/2022/21 that covers the same provisions of ECE/TRANS/WP.29/GRSP/2022/20 in a new series of amendments, and also extends the test performance of paragraph 5.7.4 (height retention of head restraints) to non-adjustable head restraint with only one position of use. The expert from CLEPA argued that the proposed deletion of the reference to UN Regulation No. 25 in both proposals would introduce unclarity when head restraint would be type approved as separate technical units. The expert from Germany stated that UN Regulation No. 25 was not updated to the technical progress. He added that the aftermarket was regulated by national law while the type approval of vehicles should be regulated by UN Regulation No. 17.

21. Finally, GRSP agreed to resume discussion on ECE/TRANS/WP.29/GRSP/2022/20 and ECE/TRANS/WP.29/GRSP/2022/21 at its May 2023 session. Moreover, GRSP agreed as a general principle that: “Not only head restraints on seats, mandatory to be fitted with head restraints according to paragraphs 5.4.1. and 5.4.2. of UN Regulation No. 17, have to be approved. All head restraints fitted on seats under the scope of UN Regulation No. 17 shall be approved.” GRSP agreed that a group of interested experts would cooperate on a solution, led by the expert from Germany.

48. The expert from Spain, Chair of IWG on safer transport of children in buses and coaches informed GRSP about GRSP-73-01 on developing the new UN Regulation. She confirmed that the Group had finalized the first phase on the use of ECRS approved according to UN Regulation No. 129 with three-point safety-belts and/or ISOFIX built-in systems. In Phase 2, she added that IWG would assess ECRS in combination with two-point belts. She added that the terms of references of Phase 2 of IWG would be prepared for comments from the Working Party on General Safety Provisions (GRSG), then for official adoption by GRSP at its December 2023 session. She then introduced GRSP-73-04-Rev.1, superseding ECE/TRANS/WP.29/GRSP/2023/2.

49. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/2, as amended by GRSP-73-04-Rev.1. The secretariat was requested to submit the proposal as a draft new UN Regulation Concerning the Approval of Child Restraint Systems for Safer Transport of Children in Buses and Coaches for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

37. The Secretary of the Task Force to transpose Amendment 1 of UN GTR No. 13 into UN Regulation No. 134 introduced GRSP-73-54, amending ECE/TRANS/WP.29/GRSP/2023/8: both were adopted by GRSP. The secretariat was requested to submit the proposal as draft 02 series of amendments to UN Regulation No. 134 for consideration and vote to the November 2023 sessions of WP.29 and AC.1.

33. The secretary of the Task Force to transpose Amendment 1 of UN GTR No. 13 into UN Regulation No. 134, introduced GRSP-72-17. GRSP noted that material compatibility, the remote Thermal Pressure Relief Device (TPRD), conformity of production and other elements proposed by GRSP-72-17 were still under discussion in the Task Force.

34. GRSP agreed to resume consideration on the transposition of UN GTR No. 13, Phase 2 into UN Regulation No. 134 on a reviewed proposal drafted by the Task Force at its May 2023 session. The proposal was expected to be submitted as an official document by 20 February 2023.

26. GRSP considered GRSP-73-17, (superseding ECE/TRANS/WP.29/GRSP/2023/10) by the expert from the Netherlands, aimed at identifying HDV equipped with an electric drivetrain. He added that the proposal of additional labelling would help emergency services to determine how to approach these vehicles in case of a fire. The expert from Japan agreed in principle with the proposal. He also introduced GRSP-73-49 to supplement it with the labelling of hydrogen- and fuel-cell vehicles, consistent with UN Regulation No. 134. The expert from the United Kingdom questioned the proposed colours of the labelling, which could conflict with those required by the 1968 Vienna Convention on Road Traffic and in national legislations. The expert from the Russian Federation presented GRSP-73-47 that introduced a proposal (GRSP-73-02) to extend the identification of vehicles to categories M and N with an electric drivetrain. He also informed GRSP that the lack of internet accessibility in numerous areas on the territory of his country would not allow viable solutions such as apps to identify electric vehicles. He added that for vehicles immersed in water (e.g. fallen from a bridge), quick response code reading (QR) would not be applicable. The expert from OICA, argued that buses already had numerous labelling and that electric vehicles with a labelling as such would come across as dangerous, creating excessive alarm for the public. The expert from the Netherland, clarified that passenger vehicles (M1) and light duty vehicles were not a priority for labels because they were covered by the Euro New Car Assessment Programme (Euro NCAP). He added that few HDV were electric-power trained, and needed to be identified for emergency services.

27. GRSP agreed to resume discussion at its December 2023 session and invited concerned parties to liaise with the expert from the Netherlands to develop a comprehensive proposal of all point views (including ECE/TRANS/WP.29/GRSP/2023/10, GRSP-73-17 and GRSP-73-49). The expert from the Russian Federation withdrew GRSP-73-02 and announced a new proposal for the next session.

43. As per paragraphs 16 and 33, the expert from the Netherlands on behalf of the Ad Hoc Group on CRS introduced ECE/TRANS/WP.29/GRSP/2023/12 and GRSP-73-19-Rev.2, to allow use of LTA. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/12 as amended by annex XI to the session report. The secretariat was requested to submit the proposal as draft 01 Series of Amendments to UN Regulation No. 145, for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

13. The expert from Japan informed GRSP that ECE/TRANS/WP.29/GRSP/2022/3 on the safety-belts of seat positions equipped with the lower ISOFIX anchorages had been shared with a group of interested experts on 8 April 2022. He clarified also that agreement had not been reached in that meeting. GRSP agreed to defer discussion on ECE/TRANS/WP.29/GRSP/2022/3 to its December 2022 session awaiting the follow-up of the group of interested parties meeting (that would be held in autumn 2022) coordinated by the expert from Japan.

16.

He added that the proposal would not mandate the use of LTA, but would ensure that use be unambiguous, and that users be informed correctly. He also explained that the proposal would be accompanied by parallel proposals to UN Regulations Nos. 129 and 145. The expert from OICA introduced GRSP-73-24 to provide consistency on transitional provisions with other proposals of amendments to the UN Regulation. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/9, as amended by annex III to the session report. GRSP requested the secretariat to submit the proposal as the draft 09 Series of Amendments to UN Regulation No. 16 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

GRSP requested the secretariat to submit the proposal as part of the draft 09 Series of Amendments (paragraphs 17 to 19) to UN Regulation No. 16 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

14. GRSP agreed to defer discussion to its May 2023 session on ECE/TRANS/WP.29/GRSP/2022/3 (safety-belts of seat positions equipped with the lower ISOFIX anchorages) while waiting for the follow-up to a meeting (January or February 2023) of a group of interested parties that would be coordinated by the expert from Japan.

16. GRSP resumed discussion on a proposal (ECE/TRANS/WP.29/GRSP/2022/13) tabled by the expert from France on clarifying the assessment of the connection of the Safety-Belt Reminder (SBR) system in the case of removable seats. GRSP also noted a presentation (GRSP-72-23) to introduce a proposal for a new series of amendments (GRSP-72-22). The expert from France explained that the proposal would clarify the requirements for SBR systems on test procedure (first- and second-level warning), visual warning and requirements for SBR in the rear seat row(s).

17. GRSP agreed to resume discussion at its May 2023 session on a revised document combining GRSP-72-22 and ECE/TRANS/WP.29/GRSP/2022/13, as a new series of amendments. GRSP requested its experts to provide feedback on GRSP-72-22 and ECE/TRANS/WP.29/GRSP/2022/13 to the expert from France before the deadline for submission of official documents for the May 2023 session.

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.

16. The expert from the Netherlands presented the status report of the Ad Hoc Group on CRS (GRSP-73-15) as an introduction to GRSP-73-16-Rev.2 (superseding ECE/TRANS/WP.29/GRSP/2023/9), which allows the use of Lower Tether Anchorages (LTA) as anti-rotation devices. He added that the proposal would not mandate the use of LTA, but would ensure that use be unambiguous, and that users be informed correctly. He also explained that the proposal would be accompanied by parallel proposals to UN Regulations Nos. 129 and 145. The expert from OICA introduced GRSP-73-24 to provide consistency on transitional provisions with other proposals of amendments to the UN Regulation. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/9, as amended by annex III to the session report. GRSP requested the secretariat to submit the proposal as the draft 09 Series of Amendments to UN Regulation No. 16 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

19. The expert from the Republic of Korea introduced the status report (GRSP-73-43) of the Ad Hoc Group on Safety-Belt Reminders (SBR). He informed GRSP that the Group agreed to clarify and resolve three SBR issues introduced at the seventy-second session of GRSP (GRSP-72-13). He concluded that the Group planned to convene virtually at the end of May to seek basis for a proposal for discussion at the December 2023 session of GRSP. The expert from France introduced ECE/TRANS/WP.29/GRSP/2023/17, to clarify: (a) how to assess SBR connection in the case of removable seats and (b) test procedure of SBR. The expert from OICA reiterated that GRSP-73-24 also amends ECE/TRANS/WP.29/GRSP/2023/17. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/17 as amended by annex III to the session report. GRSP requested the secretariat to submit the proposal as part of the draft 09 Series of Amendments (paragraphs 17 to 19) to UN Regulation No. 16 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

23. GRSP resumed discussion on a revised proposal tabled by the expert from OICA to incorporate provisions on hydrogen-fuelled vehicles into UN Regulation No. 94, to harmonize UN Regulation No. 94 with UN GTR No. 13, Amendment 1 (GRSP-73-34 superseding ECE/TRANS/WP.29/GRSP/2023/22). GRSP adopted ECE/TRANS/WP.29/GRSP/2023/22 as amended by annex V to the session report. The secretariat was requested to submit the proposal as the draft 05 Series of Amendments to UN Regulation No. 94 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

26. GRSP considered GRSP-73-17, (superseding ECE/TRANS/WP.29/GRSP/2023/10) by the expert from the Netherlands, aimed at identifying HDV equipped with an electric drivetrain. He added that the proposal of additional labelling would help emergency services to determine how to approach these vehicles in case of a fire. The expert from Japan agreed in principle with the proposal. He also introduced GRSP-73-49 to supplement it with the labelling of hydrogen- and fuel-cell vehicles, consistent with UN Regulation No. 134. The expert from the United Kingdom questioned the proposed colours of the labelling, which could conflict with those required by the 1968 Vienna Convention on Road Traffic and in national legislations. The expert from the Russian Federation presented GRSP-73-47 that introduced a proposal (GRSP-73-02) to extend the identification of vehicles to categories M and N with an electric drivetrain. He also informed GRSP that the lack of internet accessibility in numerous areas on the territory of his country would not allow viable solutions such as apps to identify electric vehicles. He added that for vehicles immersed in water (e.g. fallen from a bridge), quick response code reading (QR) would not be applicable. The expert from OICA, argued that buses already had numerous labelling and that electric vehicles with a labelling as such would come across as dangerous, creating excessive alarm for the public. The expert from the Netherland, clarified that passenger vehicles (M1) and light duty vehicles were not a priority for labels because they were covered by the Euro New Car Assessment Programme (Euro NCAP). He added that few HDV were electric-power trained, and needed to be identified for emergency services.

27. GRSP agreed to resume discussion at its December 2023 session and invited concerned parties to liaise with the expert from the Netherlands to develop a comprehensive proposal of all point views (including ECE/TRANS/WP.29/GRSP/2023/10, GRSP-73-17 and GRSP-73-49). The expert from the Russian Federation withdrew GRSP-73-02 and announced a new proposal for the next session.

171. Submitted for consideration and vote, the proposal for Amendment 1 to UN GTR No. 13 (Hydrogen and Fuel Cell Vehicles) (ECE/TRANS/WP.29/2023/81 and ECE/TRANS/WP.29/2023/82) was adopted on 21 June 2023 by consensus vote of the following contracting parties present and voting: Australia, Canada, China, European Union (representing Cyprus, Finland, France, Germany, Hungary, Italy, Lithuania, Luxembourg, Netherlands, Romania, Slovakia, Slovenia, Spain, and Sweden), India, Japan, Kazakhstan, Norway, Republic of Korea, Russian Federation, South Africa, United Kingdom of Great Britain and Northern Ireland and United States of America.

28. GRSP resumed discussion on two revised proposals tabled by the expert from France to clarify the direction of impact in the mechanical integrity test (ECE/TRANS/WP.29/GRSP/2023/16, as amended by GRSP-73-52-Rev.1, and ECE/TRANS/WP.29/GRSP/2023/23 as amended by GRSP-73-51-Rev.1).

43. As per paragraphs 16 and 33, the expert from the Netherlands on behalf of the Ad Hoc Group on CRS introduced ECE/TRANS/WP.29/GRSP/2023/12 and GRSP-73-19-Rev.2, to allow use of LTA. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/12 as amended by annex XI to the session report. The secretariat was requested to submit the proposal as draft 01 Series of Amendments to UN Regulation No. 145, for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

16. The expert from the Netherlands presented the status report of the Ad Hoc Group on CRS (GRSP-73-15) as an introduction to GRSP-73-16-Rev.2 (superseding ECE/TRANS/WP.29/GRSP/2023/9), which allows the use of Lower Tether Anchorages (LTA) as anti-rotation devices. He added that the proposal would not mandate the use of LTA, but would ensure that use be unambiguous, and that users be informed correctly. He also explained that the proposal would be accompanied by parallel proposals to UN Regulations Nos. 129 and 145. The expert from OICA introduced GRSP-73-24 to provide consistency on transitional provisions with other proposals of amendments to the UN Regulation. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/9, as amended by annex III to the session report. GRSP requested the secretariat to submit the proposal as the draft 09 Series of Amendments to UN Regulation No. 16 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

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.
