125. The expert of OICA introduced a proposal for amendments to UN Regulation No. 34 (GRSG-121-41), that aims avoid double approval with regard to fire risks by deleting the impact tests for M1 and N1 vehicles from UN Regulation No. 34. She explained that those vehicles were covered within the scope of UN Regulations Nos. 94, 95 and 153, stating that UN Regulation No. 153 covered the prevention of fire risks more appropriately than UN Regulation No. 34 as it covered fuel safety as well as electric vehicle and hydrogen safety. She invited Contracting Parties to forward their comments to the proposal to OICA.

126. GRSG considered document GRSG-121-41, proposing amendments to UN Regulation No. 34, and requested its submission as an official document for consideration at the October 2021 session of GRSG.

52. The expert from OICA introduced documents GRSG-122-10 and GRSG-122-15, proposal for Supplement 3 to the 03 series of amendments of UN Regulation No. 34 and Proposal to amend document ECE/TRANS/WP.29/GRSG/2021/19 which is a Proposal for a new 04 series of amendments of UN Regulation No. 34.

53. The expert from France recalled that para. 9.3. of UN Regulation No. 34 is not yet transposed in the UN Regulation No. 153. He therefore suggested joint activity on this proposal with GRSP to ensure alignment between the GTRs and UN Regulations. The Expert from the Russian Federation suggested a postponement of the revision of the documents GRSG-122-10 and GRSG-122-15 because the Russian Federation currently does not apply UN Regulation No. 153 and will need time to review these documents.

54. Following a detailed technical discussion from the experts from France, the Russian Federation, The European Commission and OICA with regarding the paragraph that is yet to be transposed in the UN Regulation No. 153, GRSG suggested document GRSG-122-10 be converted into an official document for reconsideration in the 123rd session of GRSG in March 2022. GRSG also suggested current document ECE/TRANS/WP.29/GRSG/2021/19 be reviewed and submitted for reconsideration at the 123rd session of GRSG as official document ECE/TRANS/WP.29/GRSG/2021/19/Rev.1.
