Proposal for corrections and clarifications to the amendments in WP.29/2022/42/Rev.1 based on GRPE/2021/21 addressing particle number emissions, including handling of electric vehicles and Conformity of Production.

Proposal for corrections and clarifications to the amendments in WP.29/2022/41/Rev.1 based on GRPE/2021/21 addressing particle number emissions, including handling of electric vehicles and Conformity of Production.

• UN R154
• Current status regarding reviewing Japan proposal on CoP section
• Current status regarding reviewing Japan proposal on PHEV calculations

• GTR 15: Annex 13
• Current status regarding GTR No.15 Annex 13

Proposal to correct inconsistencies in the time between the measurement of the end temperature and the end of the Type 1 test at 23°C for the ATCT family criterion check and in the f_jDyno force calculation.

Proposal to align with UN R48 08 series of amendments (to introduce the possibility to switch OFF rear position lamps and other lamps when ambient light conditions outside the vehicle are above 7,000 lux in order to avoid unnecessary fuel consumption). The aim of the document is to reach consensus to enable adoption of a proposal during the next GRPE session (88th session in June 2023).

Informal document GRPE-81-29 rev 1 was submitted to GRPE in June 2020 to clarify some elements surrounding the introduction of UN Regulation No. 154. This paper is updated here to add an additional clarification of the introductory provisions in the newly adopted 02 series of amendments. This document with tracked changes in word format and pdf version is also available.

Presentation on how to harmonize the requirements of the 06 and 07 series of amendments to UN R83, the 01 series of amendments to UN R101 and the original, 01, 02 and 03 series of amendments to UN R154 respectively, and to ensure consistent type-approval test conditions with the introduction of the 08 series of amendments to UN R48.

Proposal to update the 01 series of amendments with corrections and clarifications identified during the development of the 02 series of amendments.

Proposal to update the original text of UN R154 with corrections and clarifications identified during the development of the 02 series of amendments.

Proposal to introduce the possibility to switch OFF rear position lamps and other lamps when ambient light conditions outside the vehicle are above 7,000 lux in order to avoid unnecessary fuel consumption (in alignment with UN R48 wording).

Proposal to introduce particle number requirements and limits for Level 1B. The proposal also aligns the particulate measurement procedures with changes introduced in GTR No 15 Amendment 6 and other adaptations to technical progress.

Proposal to ensure that Level 2 is the latest version of this Regulation and is therefore subject to mutual recognition under the 1958 Agreement, given that there is a concurrent proposal to for an 02 series of amendments which introduces particle number requirements and limits for Level 1B. This proposal for a 03 series of amendments also aligns the particulate measurement procedures with changes introduced in GTR No 15 Amendment 6 as well as other adaptations to technical progress.

Annex B6 procedures include references to rear position and other lamps. In line with UN R48 and its 08 series of amendments which would permit switching off of rear position and other lamps when ambient light conditions are above 7,000 lux to avoid unnecessary fuel consumption, this proposal would permit ambient lighting during dynamometer operation above this threshold.
