# ASTM D4054 Clearinghouse

This document provides candidate alternative fuel producers with procedures for engaging with
the D4054 Clearinghouse to conduct evaluations of their prospective alternative fuels in
accordance with ASTM D4054 “Standard Practice for Qualification and Approval of New
Aviation Turbine Fuels and Fuel Additives.” The D4054 standard practice provides a framework
for the qualification of new fuels and additives for use in commercial aviation gas turbine
engines. The D4054 process and this procedure are intended to facilitate incorporation of the
candidate alternative fuel into ASTM D7566 “Standard Specification for Aviation Turbine Fuel
Containing Synthesized Hydrocarbons.” ASTM D7566 consists of annexes which define
physical and chemical property requirements of individual alternative fuel types. Fuels meeting
the D7566 specification can be reidentified as Jet A fuel meeting ASTM D1655 “Standard
Specification for Aviation Turbine Fuels” and enter the fungible fuel distribution system as
conventional fuels. Those alternative jet fuels that do not meet the criteria specified in any of the
current annexes of D7566 are considered candidate alternative fuels. A candidate alternative jet
fuel must be found to be fit for purpose for use in gas turbine engines and aircraft by the OEMs
that design and produce those products before it can be incorporated into D7566 as a new annex.
This fit for purpose determination is based on the data and information generated during the
D4054 evaluation process.
