Proposal to allow, at the manufacturer’s request, extension of a type approval to special purpose vehicles of categories M1, M2, N1 and N2 regardless of their reference mass provided the manufacturer demonstrates that the vehicle in question is a special purpose vehicle. This aligns UN R83 with EU Directive 2007/46/EC where approvals of vehicles with a reference mass less than 2,610 kg can be extended to special purpose vehicles exceeding 2,840 kg (e.g., armored vehicles).

Proposal to harmonize the provisions of UN Rule No. 1 with those of the latest UN Regulations annexed to the 1958 Agreement and the EU Directives.

Proposal to restrict the application of CO2 specific emission limits only to NMHC and CO emissions (back-to-back comparison of NOx and PM to apply under the regulation in any case). The proposal also aligns the text where applicable with the intent of paragraph 2.3.15.: “R49 original emission limits” means the emission limits as defined in Regulation No. 49 to which the original engine system was approved."

Proposal to allow, at the manufacturer’s request, extension of a type approval to special purpose vehicles of categories M₁, M₂, N₁ and N₂ regardless of their reference mass provided the manufacturer demonstrates that the vehicle in question is a special purpose vehicle. This aligns UN R83 with EU Directive 2007/46/EC where approvals of vehicles with a reference mass less than 2,610 kg can be extended to special purpose vehicles exceeding 2,840 kg (e.g., armored vehicles).
