160. The Chair of AC.3 recommended that AC.3 endorses ECE/TRANS/WP.29/2021/81, granting authorization to the IWG on EPPR to develop a new UN GTR on durability of after treatment devices for two- and three- wheeled motor vehicles. AC.3 adopted ECE/TRANS/WP.29/2021/81 and requested the secretariat to issue it as an AC.3 document for consideration at its next session in November 2021.

46. The Chair of IWG on EPPR presented a status report (GRPE-82-34). He detailed a draft request for authorization to develop a new UN GTR on durability of after treatment devices for two- and three- wheeled motor vehicles (GRPE-82-26-Rev.1). He also stated that this new UN GTR, once finalized, would also potentially be transposed into a UN Regulation. The secretariat asked whether this transposition would likely amend UN Regulation No. 40 or be included into a new UN Regulation. The Chair of the IWG on EPPR said this point was still being considered.

47. GRPE adopted GRPE-82-26-Rev.1, as amended by Annex VII of the session report, and requested the secretariat to submit it to WP.29 and Executive Committee of the 1998 Agreement (AC.3) for consideration and vote at their June 2021 sessions as draft request for authorization to develop a new UN GTR on durability of after treatment devices for two- and three- wheeled motor vehicles.
