Scope
GB/T 5487-2015 is the English-translated version of 汽油辛烷值的测定 研究法.
GB/T 5487-2015 is the Chinese standard "Determination of the gasoline octane number—Test method for research octane number". Its scope clause reads: 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. Its clauses include terms and definitions, abbreviations.
