1.1 This specification covers the use of purchasing agencies in formulating specifications for purchases of aviation turbine fuel under contract.

1.2 This specification defines one specific type of aviation turbine fuel for civil use in the certification of aircraft. The specification can be used as a standard in describing the quality of this aviation fuel from the refinery to the aircraft.

1.3 This specification does not include the fuels that are commonly used in aviation turbine engines. Those are listed in Specification D1655.

1.4 The aviation turbine fuel defined by this specification may be used in other than turbine engines that are specifically designed and certified for this fuel.

1.5 The use of EI/IP (Energy Institute/Institute of Petroleum) test methods is permitted. The user of this specification is referred to Specification D1655 (latest revision), Specification for Aviation Turbine Fuels, Paragraph 2, Referenced Documents and Table 1, Detailed Requirements of Aviation Turbine Fuels, Column 4, Test Methods, to determine the pairing of the IP test method with the particular detailed requirement, and to Section 11, Test Methods, to identify jointed standards and referee methods.

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

1.6.1 Exception—Units of pressure are also given in psi.

1.7 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.
