    Abstract

    This specification covers Grade 82 unleaded aviation gasoline for use only in engines and associated aircraft that are specifically approved by the engine and aircraft manufacturers, and certified by the National Certifying Agencies to use this fuel. Aviation gasoline shall consist of blends of refined hydrocarbons derived from crude petroleum, natural gasoline or blends thereof, with specific aliphatic ethers, synthetic hydrocarbons, or aromatic hydrocarbons, and when applicable, methyl tertiarybutyl ether (MTBE). They may also contain antioxidants (oxidation inhibitors), metal deactivators, corrosion inhibitors, and fuel system icing inhibitors. The gasoline shall be tested and conform accordingly to the following property requirements: lean mixture knock value and motor method octane number; color; blue and red dye content; distillation temperature at % evaporated, end point, and residue content; distillation recovery; distillation loss; net heat of combustion; freezing point; vapor pressure; lead content; copper strip corrosion; sulfur content; potential gum; and alcohols and ether content (aliphatic ethers, methanol, and ethanol).

    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. Scope

    1.1 This specification covers Grades UL82 and UL87 unleaded aviation gasolines, which are defined by this specification and are only for use in engines and associated aircraft that are specifically approved by the engine and aircraft manufacturers, and certified by the National Certifying Agencies to use these fuels. Components containing hetro-atoms (oxygenates) may be present within the limits specified.

    1.2 A fuel may be certified to meet this specification by a producer as Grade UL82 or UL87 aviation gasoline only if blended from component(s) approved for use in these grades of aviation gasoline by the refiner(s) of such components, because only the refiner(s) can attest to the component source and processing, absence of contamination, and the additives used and their concentrations. Consequently, reclassifying of any other product to Grade UL82 or Grade UL87 aviation gasoline does not meet this specification.

    1.3 Appendix X1 contains an explanation for the rationale of the specification. Appendix X2 details the reasons for the individual specification requirements.

    1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
