05 January 2018 – Baere Aerospace Consulting, Inc. has provided CAAFI with a white paper on “Considerations for Using Existing Standards as Part of Alternative Jet Fuels Approval and Deployment”, summarizing their report performed for the Coordinating Research Council (CRC) under the document AV-23-15 “Adequacy of Existing Test Methods for Aviation Jet Fuel and Additive Property Evaluation,” July 2017, available from CRCAO.org. The work entailed reviewing all of the standards and specifications referenced in ASTM D-1655 Standard Specification for Aviation Turbine Fuels, ASTM D7566, Standard Specification for Aviation Turbine Fuels Containing Synthesized Hydrocarbons, and ASTM D4054, Standard Practice for Qualification and Approval of New Aviation Turbine Fuels and Fuel Additives to determine what, if any, impact a change in the fuel composition or in how the standard was used might have on the results. The purpose of the study was to assess the continued adequacy of the referenced test standards for use with: fuels prepared in manners other than those used with traditional petroleum crude; D7566 blendstocks which may not be fluids meeting the traditional kerosene distillation profile; and additives. Out of 140 test methods identified, six documents of probable concern are presented in the white paper.
CAAFI works closely with ASTM, CRC, and other entities to enhance the certification process for alternative jet fuels.
