Standard Test Method for Determination of Octane Number of Spark-Ignition Engine Fuels by On-Line Direct Comparison Technique


Importancia y uso:

5.1 The delta octane number (ΔO.N.) measure can quantify the difference of in-line blended spark-ignition engine fuel or process stream material octane number to a desired octane number to aid in optimizing control of blender facilities or refinery process units.

5.2 The ΔO.N. measure, summed with a comparison reference fuels O.N. provides either research or motor octane number value of the current in-line blended spark-ignition engine fuel or process stream material.

5.3 Through the use of cumulative flow-proportioned averaging of the repetitive ΔO.N. results, in accordance with Practice D6624, an average octane number can be assigned to a tender or batch of in-line blended spark-ignition engine fuel.
