Abstract
A composition useful as a Reference Standard for measurement of Cetane Number or for use as a standard for determining a Derived Cetane Number consists essentially of a blend of n-hexadecane and 2,2,4,6,6-pentamethylheptane. The disclosed Reference Standards can be used directly as substitutes for blends of n-hexadecane and 2,2,4,4,6,8,8-heptamethylnonane in ASTM D613-10a for determining Cetane Number, or in ASTM D6890, ASTM D7170 or ASTM D7668 to determine a Derived Cetane Number.
