Abstract
This specification establishes the requirements for purchases of Grade UL 91 unleaded aviation gasoline under contract and is intended primarily for use by purchasing agencies. It does not cover any other gasolines satisfactory for reciprocating aviation engines. The unleaded aviation gasoline, except as otherwise specified here, shall consist of blends of refined hydrocarbons derived from crude petroleum, natural gasoline, or blends thereof, with synthetic hydrocarbons or aromatic hydrocarbons, or both. Additives for electrical conductivity and corrosion inhibition, as well as certain types of antioxidants may be added separately, or in combination, in specified compositions and concentrations. Properly sampled specimens shall undergo test procedures and conform, accordingly, to the following requirements: knock value (motor octane number); density; distillation (initial boiling point, fuel evaporated, and final boiling point); recovery, residue and loss volumes; vapor pressure; freezing point; sulfur content; net heat of combustion; corrosion (copper strip); oxidation stability (potential gum); water reaction (volume change); and electrical conductivity.
Scope
1.1 This specification covers formulating specifications for purchases of aviation gasoline under contract and is intended primarily for use by purchasing agencies.
1.2 Unleaded aviation gasoline defined by this specification is for use in engines and associated aircraft that are specifically approved by the engine and aircraft manufacturers. This fuel is not considered suitable for use in other engines and associated aircraft that are certified to use only leaded aviation gasolines of the same octane grade.
1.3 This specification, unless otherwise provided, prescribes the required properties of unleaded aviation gasoline at the time and place of delivery.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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.
