This specification covers formulating requirements for purchases of a UL100 unleaded aviation gasoline test fuel under contract and is intended solely for use by purchasing agencies for testing purposes. It prescribes the required properties of unleaded D7960 fuel at the time and place of delivery. The suitability of this fuel for use on any specific aircraft, aircraft engine, or ground-based fuel handling equipment should be evaluated before use on that equipment.

Included in this specification are requirements for the manufacture of D7960 fuel and additives; workmanship, finish, and appearance; sampling; and the type and number of reports to ensure conformance with the requirements of this specification. Products shall conform to the requirements that shall be determined in accordance with ASTM test methods for knock value (lean rating), tetraethyl lead, density, distillation, vapor pressure, freezing point, sulfur, net heat of combustion, corrosion (copper strip), potential gum and visible lead precipitate, water reaction, and electrical conductivity.

1.1 This specification covers formulating specifications for purchases of a UL102 unleaded aviation gasoline test fuel under contract and is intended solely for use by purchasing agencies for testing purposes.

1.2 This specification defines a specific type of aviation gasoline for use as an aviation spark-ignition engine test fuel. It does not include all gasolines satisfactory for reciprocating aviation engines. Certain equipment or conditions of use may permit a wider, or require a narrower, range of characteristics than is shown by this specification.

1.3 The D7960 test fuel defined by this specification may not exhibit identical performance to those leaded fuels with which the existing aircraft and ground-based fuel handling equipment have been designed to operate. Therefore, the suitability of this fuel for use on any specific aircraft, aircraft engine, or ground-based fuel handling equipment should be evaluated before use on that equipment.

1.4 Issuance of this specification does not constitute approval to operate certificated aircraft with this fuel. Fuels used in certified engines and aircraft are ultimately approved by the certifying authority subsequent to formal submission of evidence to the authority as part of the certification program for that aircraft and engine model.

1.5 This specification, unless otherwise provided, prescribes the required properties of unleaded D7960 test fuel at the time and place of delivery.

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

1.7 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.
