Standard ASTM D7566-15A
1.1 This specification covers the manufacture of aviation turbine fuel that consists of conventional and synthetic blending components.
1.2 This specification applies only at the point of batch origination, as follows:
1.2.1 Aviation turbine fuel manufactured, certified, and released to all the requirements of Table 1 of this specification ( ), meets the requirements of Specification and shall be regarded as Specification turbine fuel. Duplicate testing is not necessary; the same data may be used for both and compliance. Once the fuel is released to this specification ( ) the unique requirements of this specification are no longer applicable: any recertification shall be done in accordance with Table 1 of Specification .
1.2.2 Field blending of synthesized paraffinic kerosine (SPK) blendstocks, as described in (FT SPK), (HEFA SPK), or (SIP) with fuel (which may on the whole or in part have originated as fue
l) shall be considered batch origination in which case all of the requirements of Table 1 of this specification ( ) 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 turbine fuel after certification and release as described in .
1.2.3 Once a fuel is redesignated as aviation turbine fuel, it can be handled in the same fashion as the equivalent refined aviation turbine fuel.
1.3 This specification defines specific types of aviation turbine fuel that contain synthesized hydrocarbons for civil use in the operation and certification of aircraft and describes fuels found satisfactory for the operation of aircraft and engines. The specification is intended to be used as a standard in describing the quality of aviation turbine fuels and synthetic blending components at the place of manufacture but can be used to describe the quality of aviation turbine fuels for contractual transfer at all points in the distribution system.
1.4 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.
1.5 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.
1.6 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.
1.7 Synthetic blending components, synthetic fuels, and blends of synthetic fuels with conventional petroleum-derived fuels in this specification have been evaluated and approved in accordance with the principles established in Practice .
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.9 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.
