Proposal to introduce provisions specific to special-purpose vehicles.

Proposal to correct the recursive formula of the 05, 06 and 07 series of amendments to UN Regulation No. 83 in the procedure for verifying the conformity of production requirements if the production standard deviation given by the manufacturer is either not satisfactory or not available.

Proposal to permit use of equipment conforming to UN R154 for testing under UN R83 (and by extension to UN R101 which references UN R83).

Proposal to correct the recursive formula in the procedure for verifying the conformity of production requirements if the production standard deviation given by the manufacturer is either not satisfactory or not available.

Proposal to harmonize:

• 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.
• Preconditioning requirement (Annex 9, determination of electric range) and UN R83 (Annex 14, provisions for emissions test procedures for HEV).

Annex 4A-Type 1 tests include references to daytime running lamps and 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.

Annex 5 procedures include references to daytime running lamps and 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.

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.

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.
