ASTM WK43188

    Revision of D7719 - 12 Standard Specification for High Octane Unleaded Test Fuel

    (What is a Work Item?)

    Active Standard: D7719 - 14c

    Developed by Subcommittee: D02.J0 | Committee D02 | Contact Staff Manager


    1. Rationale

    The Subcommittee D02.J0 D7719 task force would like to: 1. Update the specification title and scope statements in the specification to convert the specification to a production specification and in order to harmonize it with other aviation gasoline standards, including D910 and D7547. 2. Move the introduction statement to the appendix, to match the formatting of similar specifications. A research report has been prepared and balloted with the D02.J0 subcommittee, with the supporting data. Since the publication of ASTM D7719 in May 2011, a significant amount of work has taken place to expand the scope and depth of the research presented in the initial research report, which presented proof-of-concept-level data on Grade UL102 fuel. During this time, a more complete cross-section of the fleet was examined in order to fill in some of the remaining holes in fit-for-purpose data for UL102, such as materials compatibility, environmental and toxicology data, etc., that has to be shown before the fuel is commercialized. This proposed transition does not, of course, mean to take the place of any regulatory or OEM approval that has to occur before fuel may be sold commercially. Rather, it gives suppliers a way to prove that the fuel they are providing is consistent and repeatable not only when being sold commercially but when the fuel is being tested in specialized, controlled environments as well. One particular test for which consistent, repeatable fuel is of paramount importance is an FAA Supplemental Type Certificate (STC). In the case of Grade UL102, an STC program is ongoing for a Cessna 172. In addition, with an STC, a production specification is required for final approval of the STC by FAA authorities. On previous ballots, the task force received comments suggesting that the introduction appearing on the first page of the specification should appear in the appendix section X1.1. This ballot addresses those comments. An accompanying research report has been prepared and is included as a separate item on the D02.J0 13-04 ballot. The Research Report was sent out in sections in the months prior to this ballot, as a courtesy to voters to give them more time to read the material, as the report is rather comprehensive.
