Annotation of standard text ASTM D7719-21a :

This specification covers formulating specifications for purchases of a high octane unleaded test fuel under contract and is intended solely for use by purchasing agencies for testing purposes. This specification also defines a specific type of high octane unleaded test fuel for use as an aviation spark-ignition fuel. A new high-octane unleaded test fuel has been developed, which maintains the key performance parameters of existing reciprocating aircraft engines.

Keywords:

aviation gasoline, binary, hydrocarbon, unleaded,, ICS Number Code 75.160.20 (Liquid fuels)

Additional information

1. Scope

1.1?This specification covers formulating specifications for purchases of a high aromatic content unleaded hydrocarbon aviation gasoline test fuel under contract and is intended solely for use by purchasing agencies for testing purposes.2

1.2?This specification defines a specific type of high aromatic content unleaded hydrocarbon aviation gasoline (hereafter also referred to as D7719 fuel) for use as an aviation spark-ignition test fuel. It does not include all fuels 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 D7719 fuel defined by this specification does not exhibit identical performance to those leaded fuels for which the existing aircraft and ground-based fuel handling equipment have been designed to operate on. Therefore, the suitability of this test 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 D7719 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.8?This 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.
