Uncertainty in measurements is a complex issue to obtain accurate results in vehicle fuel consumption tests. Petrobras Research Center carried out a study to calculate the final uncertainty of measurement during a vehicle fuel economy test following a feasible method that can be used in many laboratories.This study was based on the ISO-GUM (Guide to the expression of uncertainty in measurement) and on the Brazilian legislations ABNT NBR-6601 (pollutant emission) [1] and NBR-7024 (fuel economy tests) [2].
