1.1 This practice covers and provides instructions on making a volumetric blend of denatured fuel ethanol with gasoline blendstocks, such as a reformulated gasoline blendstock for oxygenate blending (RBOB) or a conventional gasoline blendstock for oxygenate blending (CBOB).

1.2 This practice does not preclude the use of automated volumetric blending systems.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.


Typically, denatured fuel ethanol is added to gasoline blendstocks after production. For laboratories to test a sample that is similar to the finished fuel available in the market, it is important to provide a laboratory practice that standardizes the preparation of a blend of denatured fuel ethanol and gasoline blendstock.

The laboratory blend shall be prepared volumetrically to yield a fuel similar to that produced for consumer use.

When applicable, blends shall meet requirements of CFR 40.80, Subpart DReformulated Gasoline.
