The following bibliographic material is provided to assist you with your purchasing decision:
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 Once the fuel is released to this specification ( ) the unique requirements of this specification are no longer applicable: any recertification shall be done in accordance with Table 1 of Specification .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), (SIP), synthesized paraffinic kerosine plus aromatics (SPK/A), (ATJ), catalytic hydrothermolysis jet (CHJ), or (HC-HEFA SPK) with fuel (which may on the whole or in part have originated as fuel) 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 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 is directed at civil applications, and maintained as such, but may be adopted for military, government, or other specialized uses.
1.4 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.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.10 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.
