ASTM D7566-23a

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D7566 − 23 D7566 − 23a
Standard Specification for
Aviation Turbine Fuel Containing Synthesized

Hydrocarbons
This standard is issued under the fixed designation D7566; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 This specification covers the manufacture of aviation turbine fuel that consists of conventional and synthetic blending
components.
1.2 See Appendix X2 for an expanded description of the procedure for the production and blending of synthetic blend components.
1.3 This specification applies only at the point of batch origination, as follows:
1.3.1 Aviation turbine fuel manufactured, certified, and released to all the requirements of Table 1 of this specification (D7566),
meets the requirements of Specification D1655 and shall be regarded as Specification D1655 turbine fuel. Duplicate testing is not
necessary; the same data may be used for both D7566 and D1655 compliance. Once the fuel is released to this specification
(D7566) the unique requirements of this specification are no longer applicable: any recertification shall be done in accordance with
Table 1 of Specification D1655.
1.3.2 Any location at which blending of synthetic blending components specified in Annex A1 (FT SPK), Annex A2 (HEFA SPK),
Annex A3 (SIP), Annex A4 synthesized paraffinic kerosine plus aromatics (SPK/A), Annex A5 (ATJ), Annex A6 catalytic
hydrothermolysis jet (CHJ), or Annex A7 (HC-HEFA SPK) SPK), or Annex A8 (ATJ-SKA) with D1655 fuel (which may on the
whole or in part have originated as D7566 fuel) or with conventional blending components takes place shall be considered batch
origination in which case all of the requirements of Table 1 of this specification (D7566) apply and shall be evaluated. Short form
conformance test programs commonly used to ensure transportation quality are not sufficient. The fuel shall be regarded as D1655
turbine fuel after certification and release as described in 1.3.1.
1.3.3 Once a fuel is redesignated as D1655 aviation turbine fuel, it can be handled in the same fashion as the equivalent refined
D1655 aviation turbine fuel.
1.4 This specification defines the minimum property requirements for aviation turbine fuel that contain synthesized hydrocarbons
and lists acceptable additives for use in civil operated engines and aircrafts. Specification D7566 is directed at civil applications,
and maintained as such, but may be adopted for military, government, or other specialized uses.
1.5 This specification can be used as a standard in describing the quality of aviation turbine fuel from production to the aircraft.

However, this specification does not define the quality assurance testing and procedures necessary to ensure that fuel in the
distribution system continues to comply with this specification after batch certification. Such procedures are defined elsewhere, for
example in ICAO 9977, EI/JIG Standard 1530, JIG 1, JIG 2, API 1543, API 1595, and ATA-103, and IATA Guidance Material for
Sustainable Aviation Fuel Management.
1.6 This specification does not include all fuels satisfactory for aviation turbine engines. Certain equipment or conditions of use
may permit a wider, or require a narrower, range of characteristics than is shown by this specification.
1.7 While aviation turbine fuels defined by Table 1 of this specification can be used in applications other than aviation turbine
engines, requirements for such other applications have not been considered in the development of this specification.
