denatured fuel ethanol, gasoline blendstocks, volumetric blends,, ICS Number Code 75.160.20 (Liquid fuels)
|Significance and Use|
5.1Typically, 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.
5.2The laboratory blend shall be prepared volumetrically to yield a fuel similar to that produced for consumer use.
5.3When applicable, blends shall meet requirements of CFR 40.80, Subpart DReformulated Gasoline.
1.1This 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).
1.2This practice does not preclude the use of automated volumetric blending systems.
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
