Abstract Octane number testing system is set up in order to get the octane number of gasoline. The components of uncertainty influencing on the measurement of octane number, including automatic manufacture standard sample machine, repeated test of octane number and CFR engine, are analyzed in the system. The uncertainty are calculated. Synthesizing the uncertainty results of all the components show that octane number testing system for the expanded uncertainty of research octane numeber is 0.7 at 95% confidence level, which meet the demand for measurement uncertainty of gasoline fuel.
