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 adopted.]
38. The expert from the EC introduced ECE/TRANS/WP.29/GRPE/2013/8 and GRPE-66-10, containing modifications to the 06 series of amendments of UN Regulation No. 49 that aim to reduce the risks of misinterpretations of the regulatory text.
39. The expert from OICA presented GRPE-66-35-Rev.1, introducing the possibility to temporarily disable the OBD system for very low temperatures (first suggesting -18°C as a threshold, and later agreeing to use -22°C), arguing that only a fraction of vehicle km are run in these conditions and that the accuracy of the OBD devices is hampered at very low temperatures. Notwithstanding the need to ensure that the regulation of pollutant emission needs to be enforced also in the coldest regions and cities, the expert from Sweden accepted the proposal with a -22°C threshold. The expert from Norway supported the Swedish statement. The expert from the EC also supported the Swedish position, underlining that the deactivation shall be limited to the period of time during which the temperatures remain below the deactivation threshold.
40. GRPE adopted ECE/TRANS/WP.29/GRPE/2013/7, as amended by GRPE-66-25, and ECE/TRANS/WP.29/GRPE/2013/8, as amended by GRPE-66-10 and GRPE-66-35-Rev.1. GRPE requested the secretariat to submit the resulting proposals to WP.29 and AC.1, for consideration at their November 2013 sessions, respectively as Supplement 6 to the 05 series of amendments to Regulation No. 49 and Supplement 2 to the 06 series of amendments to Regulation No. 49.
