RS ISO 5164: 2014
Standard test method for research octane number of spark-ignition engine fuel


This International Standard establishes the rating of liquid spark-ignition engine fuel in terms of
an arbitrary scale of octane numbers using a standard single-cylinder, four-stroke cycle, variable
compression ratio, carburetted, CFR engine operated at constant speed. Research octane number
(RON) provides a measure of the knock characteristics of motor fuels in automotive engines under mild
conditions of operation.
