Proposal to add assembly plant(s) to the approval information document.

Proposal to correct drafting errors in the text.

Proposal to permit the use of hydrogen (H2) as fuel for emissions type approval of heavy-duty vehicles, to insert provisions in Supplement 7 to the 06 series that were unintentionally omitted, to add a requirement for the accuracy of the humidity sensor, correct a typographical error (NOx mode), and to clarify the procedures.

Proposal to introduce SAE standard J1979-2 (E/E Diagnostic Test Modes: OBDonUDS) as an option into the Regulation and to align 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.

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), to introduce the option to use of SAE standard J1979-2 (E/E Diagnostic Test Modes: OBDonUDS), to align wording between the first sentence of paragraph 3.2.1.2. (“ambient or engine temperatures”) and the second sentence (where “or engine” was omitted), and to align paragraph 6.5.1.3. with GTR No. 15.

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), to introduce the option to use of SAE standard J1979-2 (E/E Diagnostic Test Modes: OBDonUDS), to align wording between the first sentence of paragraph 3.2.1.2. (“ambient or engine temperatures”) and the second sentence (where “or engine” was omitted), and to align paragraph 6.5.1.3. with GTR No. 15.

Proposal to permit the use of hydrogen (H2) as fuel for type approval of heavy-duty vehicles and to explicitly permit the usage of the reference fuel required for emission testing when the manufacturer applies for UN Regulations Nos. 24 and/or 49 type approval at same time.

Proposal to reaffirm Japan’s Real Driving Emissions (RDE) Methodology.

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), to harmonize the requirements for the determination of CO2, fuel, and electric energy consumption of the discharge requirement for OVC-HEV with an operating mode switch with its stop criterion and the preconditioning requirement with the 01 series of amendments to UN R101 and 06 and 07 series of amendments of UN R83 (Annex 14, provisions for emissions test procedures for HEV), and to add assembly plant(s) to the approval information document.
