Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This laboratory test meth

However, this test methodmay not be applicable to fuel and fuel components that areprimarily oxygenates.2The sample fuel i

The O.N. scale is definedby the volumetric composition of PRF blends. The sample fuelknock intensity is compared to that o
5、f one or more PRF blends.The O.N. of the PRF blend that matches the K.I. of the samplefuel establishes the Research O.N.1.2 The O.N. scale covers the range from 0 to 120 octanenumber but this test method has a working range from 40 to120 Research O.N. Typical commercial fuels produced forspark-ignit

Testing of gasoline blend stocks or other process streammaterials can produce ratings at various levels throughout theResearch O.N. range.1.3 The values of operating conditions are stated in SI unitsand are considered standard. The values in pare

The standardized CFR enginemeasurements continue to be in inch-pound units only becauseof the extensive and expensive tooling that has been created forthis equipment.1.4 For purposes of determining conformance with allspecified limits in this standard, an
