ASTM Petroleum Committee working on ETBE test method
The eventual approval of a proposed new test method currently being developed by ASTM International Committee D02 on Petroleum Products and Lubricants will allow a recently approved D02 specification to attain full compliance with form and style for ASTM standards.
The proposed new standard, ASTM WK30961, “Test method for analysis of ethyl tertiary-butyl ether (ETBE) by gas chromatography,” is currently being developed by Subcommittee D02.J0.02 on Aviation Gasoline, part of Section D02.J0 on Aviation Fuels.
According to Cesar Gonzalez, an independent consultant and longtime D02 member, ASTM D7618, “Specification for ETBE for blending with aviation spark ignition engine fuel,” currently incorporates an annex, A1, “Modification to test method D5441, test method for analysis of ETBE by gas chromatography.” However, in order to comply fully with ASTM form and style, the annex must be replaced by an independent ETBE test method with appropriate precision and bias statements. ASTM WK30961 will be that test method.
“ETBE blends with motor gasoline and aviation gasoline hydrocarbon stock offer proven medium and high octane aviation fuel potentials unmatched by other oxygenate or hydrocarbon components,” said Mr. Gonzalez. “A gradual reduction and eventual elimination of lead additives can be safely, practically and economically attained by replacing lead components with ETBE.”
ASTM International welcomes and encourages participation in the development of its standards. For more information on becoming an ASTM member, visit www.astm.org/JOIN.
