Proposal based on the 07 series of amendments to remove elements which covered by UN R154 (WLTP), to include references to the draft UN Regulation on Real Driving Emissions (RDE), and to update In-Service Conformity (ISC) requirements for the purposes of establishing regional type approval equivalence. The proposal is incomplete. The EC expects to provide missing elements before the 87th GRPE session in January 2023. This document is available with mark-ups in pdf version and in docx format.

Proposal to harmonize the requirements of the 06 and 07 series of amendments, align with UN R48 wording to ensure consistent type-approval test conditions with the introduction of the 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).

Proposal for changes to the draft amendments to the 05, 06, and 07 series per the following justifications:

1. In GRPE-86-12, the introduction of SAE J 1979-2 was proposed for Series 05, 06 and 07 of Regulation No. 83. Due to the different structure of Series 05 and 06 compared to 07, this proposal was not adopted. This proposal introduces the new standard to Series 05 and 06 and aligns the standards with Series 07.
2. The standards used for transmission of OBD information are maintained by international standardisation bodies (ISO, SAE). These standardisation body have to be informed.
3. Alignment of wording between the first sentence of paragraph 3.2.1.2. (“ambient or engine temperatures”) and the second sentence, where “or engine” was missing to avoid misunderstanding and ambiguity. Engine temperature is sometimes used as a substitute for ambient temperature. In this case, the engine temperature is evaluated once after a longer engine shut off phase. Only in this case an approval is necessary, as this is the only case, where an OBD monitor is disabled for the complete trip.
4. Align Paragraph 6.5.1.3. with GTR No. 15 to avoid ambiguity.

Proposal of amendments to promote harmonization, legal certainty, and environmental protection in the 08 series of amendments.
