1.1 This practice covers and provides a framework for the Original Equipment Manufacturer (OEM) evaluation and ap-proval of new fuels and new fuel additives for use in commercial and military aviation gas turbine engines. The practice was developed as a guide by the aviation gas-turbine engine Original Equipment Manufacturers (OEMs) with ASTM International member support. The OEMs are solely responsible for approval of a fuel or additive in their respective engines and airframes. Standards organizations such as ASTM International (Subcommittee D02J0), United Kingdom Minis- try of Defence, and the U.S. Military list only those fuels and additives that are mutually acceptable to all OEMs. ASTM International and OEM participation in the evaluation proce-dure does not constitute an endorsement of the fuel or additive.
