GRBP | Session 71 | 28-31 Jan 2020

12. The expert from ETRTO introduced a new Supplement to UN Regulation No. 30 and an accompanying transitional provision (paragraph 11.4.) that would delay for three months the mandatory application of the Supplement (ECE/TRANS/WP.29/GRBP/2020/3). In particular, he proposed excluding tyres with radial and run flat structure from the dimensional requirements after the load speed endurance test (GRBP-71-07). Various experts commented on the proposal and suggested modifications (GRBP-71-30). Finally, GRBP adopted the proposal, as contained in Annex VI, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their June 2020 sessions as Supplement 22 to the 02 series of amendments to UN Regulation No. 30.

13. GRBP noted that the adopted transitional provision 11.4. does not contradict the WP.29 Guidelines for regulatory procedures and transitional provisions in UN Regulations (ECE/TRANS/WP.29/1044/Rev.2). At the same time, several GRBP experts expressed concerns about the rationale given by ETRTO for this provision which was the delays in issuance by the United Nations Office for Legal Affairs (OLA) of depository notifications about the entry into force of amendments to UN Regulations. GRBP was of the view that this is a general problem that affects all UN Regulations and other WP.29 Working Parties as well. Therefore, GRBP requested the Chair to raise this issue at the next session of the Administrative Committee for Coordination of Work (AC.2).

GRBP | Session 72 | 7-9 Sep 2020

14. The expert from ETRTO proposed several modifications (ECE/TRANS/WP.29/GRBP/2020/14, GRBP-71-07-Rev.1 and GRBP-72-28). GRBP adopted the proposal, as amended by Annex VI of the session report, and requested the secretariat to submit it to WP.29 and AC.1 for consideration and vote at their March 2021 sessions as a draft Supplement 19 to the original series of amendments to UN Regulation No. 75.
