    1. Rationale

    ASTM D7566-09, Standard Specifications For Aviation Turbine Fuels Containing Synthesized Hydrocarbons was issued in September 2009. This specification was issued in response to the demand expressed by the USAF and commercial operators of turbine engine powered aircraft for alternatives to conventional petroleum-derived jet fuel. The current version of this specification, ASTM D 7566-13, includes Fischer-Tropsch hydroprocessed synthesized paraffinic kerosine (FT-SPK) and synthesized paraffinic kerosine from hydroprocessed esters and fatty acids (HEFA SPK) as approved synthetic blending components in Annexes A1 and A2 respectively. This ballot proposes to add a new Annex, A3, to incorporate synthesized iso-paraffins (SIP) as a third approved synthetic blending component. This blending component will be called synthesized iso-paraffins produced from hydroprocessed fermented sugars and will be permitted for blending at up to 10% (vol) with conventional jet fuel. The inclusion of synthesized iso-paraffins paraffins produced from hydroprocessed fermented sugars synthetic blending component is based on an extensive evaluation of this blending component neat and in blend with conventional jet fuel. The evaluation was conducted in accordance with ASTM D4054-09, Standard Practice for Qualification and Approval of New Aviation Turbine Fuels and Fuel Additives to ensure that jet fuels containing the SIP blending component at up to 10% volume would not adversely impact turbine engine safety, durability, or performance. This evaluation is summarized in ASTM Research Report Synthesized Iso- Paraffins produced from Hydroprocessed Fermented Sugars (SIP Fuels), prepared by the TOTAL, Amyris, and United States Air Force Research Laboratory (AFRL), Version 3.0, February 2014. The research report concluded that jet fuels containing up to 10% volume of the SIP synthesized blending component provide fit-for-purpose performance.
