RS ASTM D 2700: 2018
Standard test method for motor octane number of spark— ignition engine fuel
Abstract

This laboratory test method covers the quantitative determination of the knock rating of liquid spark-ignition engine
fuel in terms of Motor octane number, including fuels that contain up to 25 % v/v of ethanol. However, this test method may
not be applicable to fuel and fuel components that are primarily oxygenates.2 The sample fuel is tested in a standardized single
cylinder, four-stroke cycle, variable compression ratio, carbureted, CFR engine run in accordance with a defined set of
operating conditions. The octane number scale is defined by the volumetric composition of primary reference fuel blends. The
sample fuel knock intensity is compared to that of one or more primary reference fuel blends. The octane number of the
primary reference fuel blend that matches the knock intensity of the sample fuel establishes the Motor octane number.
