Summary This standard specifies the test method for the determination of octane number of gasoline by the CFR octane test machine (research method). This standard is applicable to the determination of the octane number of the Ignition Engine Fuel Law and does not apply to fuels and their fuel components consisting essentially of oxygen-containing compounds. Note: The octane number ranges from 0 to 120, but the effective method of this standard is to measure the range of 40 to 120. The commercial octane number ranges from 88 to 101 for commercial spark ignition engines, and octane numbers for gasoline grades or other liquid substances. The values ??for the operating conditions of this standard are expressed in SI units, in brackets, in English units, and for standard CFR engines, in imperial units.

1 Scope

This standard specifies the gasoline octane number (research) Test Method for measuring CFR octane rating equipment. This standard is applicable to the determination ignition engine fuel in research octane number, it does not apply to fuel composed mainly of oxygen-containing compounds and Its fuel component. Note. The octane number in the range of 0 to 120, but the present standard of effective research octane number measurement range from 40 to 120. Automotive Spark Ignition Engine City Research octane fuel sold in the range of 88 to 101 can be obtained through the study of different grades of gasoline blending component testing or other liquid substances Octane. The value of the standard operating conditions with [SI] SI units, said Imperial units in parentheses represent values \u200b\u200bfor reference standards for CFR engine technical requirements in imperial units.
