5. (d) | UN Regulation No. 109 (Retreaded tyres for commercial vehicles and their trailers)

17. The expert from France proposed aligning the test procedures in UN Regulation No. 109 with those in UN Regulation No. 117 (ECE/TRANS/WP.29/GRBP/2023/4). Subject to replacement of “Annex 7” with “Annex 10” in the introductory line, GRBP adopted the proposal and requested the secretariat to submit it for consideration and vote at the June 2023 sessions of WP.29 and AC.1 as draft Supplement 12 to UN Regulation No. 109.

4.6. | Consideration of draft amendments to existing UN Regulations submitted by GRBP

78. The World Forum considered draft amendments under agenda items 4.6.1 to 4.6.7. and recommended their submission to AC.1 for voting, subject to the following corrections of ECE/TRANS/WP.29/2021/8 under agenda item 4.6.6 (WP.29-183-06):
In paragraph 4.4.1., replace “markings” with “approval mark”.
In paragraph 9.1., delete from the proposal (i.e. keep the paragraph in its current form).

79. The Chair of GRBP presented draft amendment proposals contained in documents ECE/TRANS/WP.29/2021/3, ECE/TRANS/WP.29/2021/10 and Rev.1, ECE/TRANS/WP.29/2021/11 under agenda item 4.6.8 to 4.6.10., to amend UN Regulations Nos. 41, 141 and 142. The World Forum recommended their submission to AC.1 for voting.

4.6.6. | Proposal for Supplement 13 to the 02 series of amendments to UN Regulation No. 117 (Tyre rolling resistance, rolling noise and wet grip)
5. (e) | UN Regulation No. 117 (Tyre rolling resistance, rolling noise and wet grip)

16. The expert from ETRTO introduced an amendment proposal with the aim to improve the reproducibility of the test method from standard ISO 23671 (ECE/TRANS/WP.29/GRBP/2020/16). Following concerns of the experts from Germany and Spain about paragraph 4.1.2.1. of Annex 5, part A, the expert from ETRTO proposed a modification to this paragraph (GRBP-72-29). GRBP adopted the proposal, as amended by Annex VIII of the session report, and requested the secretariat to submit it to WP.29 for consideration and vote at their March 2021 sessions as a draft Supplement 13 to the 02 series of amendments to UN Regulation No. 117.

17. The expert from ETRTO proposed further amendments with a view to modifying the word “moulded” in tyre marking methods and replacing the Standard Reference Test Tyre SRTT14 by SRTT16 (ECE/TRANS/WP.29/GRBP/2020/17). GRBP adopted the proposal, subject to deletion of paragraph 9.1., and requested the secretariat to submit it to WP.29 and for consideration and vote at their March 2021 sessions as part of draft Supplement 13 to the 02 series of amendments to UN Regulation No. 117.
