UN R115 and R83: Correction Factor for G-25 Weighting Process

Reference Number: GFV-20-05

Documents GRPE/2012/6 and 7 introduce the calculation of NG/biomethane energy ratio during a type I cycle by weighing the NG/biomethane mass consumed. The formulas are affected by an error when G25 reference fuel is used. This proposal precribes a modification to the previous formulas.

Submitted by: AEB Tech and Landi Renzo
