This specification covers butanol intended to be blended with gasoline at 1 to 12.5 volume % for use as an automotive spark-ignition engine fuel. It addresses performance requirements, workmanship, sampling, containers, sample handling, and test methods.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers butanol intended to be blended with gasoline at 1 % to 12.5 % by volume for use as an automotive spark-ignition engine fuel.
1.1.1 Butanol contains 22 % by mass oxygen. The mass percent of oxygen of a butanol blend with gasoline depends on the volume percent of butanol blended, the density of the butanol isomer, and the density of the base blendstock.
1.1.2 The maximum limit on blending is not a performance limit but a current regulatory limit in the United States.
1.2 This specification covers three butanol isomers:1-butanol, 2-butanol, and 2-methyl-1-propanol. This specification specifically excludes 2-methyl-2-propanol (that is, tert-butyl alcohol).
1.2.1 Tert-butyl alcohol has different physical properties (melting point, water miscibility) than the other three isomers.
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.
