Document Title	UN R83: Proposal for additional content in GRPE/2023/10
Reference Number	GRPE-87-13/Rev.2
Date	31 Jan 2023
Summary	Proposal for changes to the draft amendments to the 05, 06, and 07 series per the following justifications: 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. The standards used for transmission of OBD information are maintained by international standardisation bodies (ISO, SAE). These standardisation body have to be informed. 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. Align Paragraph 6.5.1.3. with GTR No. 15 to avoid ambiguity.
