Proposal from the GFV Informal Group. FCmean, as defined in paragraphs 6.1.2.4.3.2. (LPG) and 6.2.2.4.3.2. (CNG) of UN Regulation No. 115, is the mean value of the fuel consumptions of all the parent (test) vehicles, whereas the calculation of the gas ratio has to be made individually for each parent vehicle.
Therefore, FCmean has to be replaced by FCnorm as defined in UN R101.
This correction would align UN R115 with the corresponding provisions set out in UN R83
[Proposal adopted.]
42. The GFV Chair illustrated a proposal to amend UN Regulation No. 115 (GRPE-66-19), correcting an error and aligning its provision to the corresponding ones in UN Regulation No. 83. Given the nature of the amendment, the expert from Italy suggested submitting the proposal, on an exceptional basis, directly to WP.29.
43. GRPE asked the secretariat to submit GRPE-66-19, as reproduced in Annex IV, as a working document directly to WP.29 and AC.1, for consideration at their November 2013 sessions, as Supplement 6 to UN Regulation No. 115.
