As the Euro VI standards for heavy duty vehicles become mandatory throughout the European Union, manufacturers may adapt their certification processes to take account of the extended scope of Euro VI compared to Euro V. In order to prevent inconsistencies that could affect the ability to offer all vehicles for export, it is proposed to carry back this scope amendment retrospectively to the 05 series of amendments.

Since Euro VI will be fully implemented in the EU from 31 December 2013, this amendment has no effect on EU Approvals or equivalences.

Proposal to correct provisions concerning permissions to disable OBD system monitors during testing under certain altitude and temperature conditions contained in the proposal to revise the 06 series of amendments to UN R49.

GRPE-approved text, based on a proposal prepared by the Euro VI Expert Working Group of the European Commission to revise the 06 series of amendments to UN R49 in order to address situations that were not covered by the latest series of amendments and to clarify the text.

Proposal as approved by the GRPE to introduce type-approval provisions for vehicles equipped with LNG propulsion systems and to extend the pollutant emission requirements of the regulation to dual-fuel heavy duty engines and vehicles.

UNECE report in response to World Health Organization concerns over vehicle emissions, in particular diesel particulates.

Revised proposal to introduce an amendment to documents GRPE/2013/8 and GRPE-66-10 that would permit the manufacturer to request a temporary disablement of OBD monitors at low ambient temperature in the same manner as permitted at high ambient temperatures (above 35°C).

Document GRPE/2013/7 was prepared to modify the 05 series of amendments of UN R49 (Euro V) in order to extend the pollutant emission requirements to dual-fuel heavy duty engines and vehicles. Per agreement with GRPE, this document proposes amendments to the 05 series based on the latest GFV work.

Heavy Duty Dual Fuel Task Force proposal to modify the 05 series of amendments of UN Regulation No. 49 (Euro V) in order to extend the pollutant emission requirements to dual-fuel heavy duty engines and vehicles.

Text prepared by the Euro VI Expert Working Group of the European Commission to revise the 06 series of amendments to UN R49 in order to address situations that were not covered by the latest series of amendments and to clarify the text.

Text prepared by the Chair of the Gaseous Fuelled Vehicles informal group–Heavy Duty Dual Fuel task force to introduce modifications to the 05 series of amendments of UN R49 (Euro V) in order to extend the pollutant emission requirements to dual-fuel heavy duty engines and vehicles.

Some corrections to Annex 4B were introduced when that Annex was merged into the new Annex 4 in Revision 6 of UN R49. These corrections were not carried over into Annex 4B as it stands in Revision 5; however, some of these are necessary for dual-fuel engines and vehicles. The chair of the GFV Heavy-duty Dual Fuel Task Force has prepared this document to correct the oversight.

Text as prepared by the informal HDDF Task Force within the GFV informal working group in order to enable the type approval of new EURO V heavy duty dual-fuel engines and vehicles
