B6 to B20 blends are newly specified; diesel and burner fuel specifications are revised to include up to B5 blends Higher costs at the pump, renewable energy and alternate sources continue to headline today's news, and a group of newly published ASTM International specifications sets the standard for one type of these fuels: biodiesel. Four standards now available from ASTM International provide…

Four ASTM International standards that specify biodiesel have achieved final ASTM approval and will proceed toward publication and availability, which is anticipated for mid-October. The new and newly revised specifications will be used in engine design, to include in bid and purchasing contracts or to check fuel quality at the pump. The standards include the following: ASTM D975-08a ,…

REPORT ON THE JUNE 3-5, 2008, MEETING OF ASTM SUBCOMMITTEE D02.J ON AVIATION FUELS IN WARSAW, POLANDThe agenda for the meeting of ASTM Subcommittee D02.J on Aviation Fuels held in June 2008 is geared to the pertinent discussions concerning aviation turbine fuels and aviation gasoline, since there is much interest for the approval of biomass-produced fuels that would help reduce key greenhouse gases such as carbon dioxide (CO 2 ). In addition to these topics, task force meetings were held to…, Section J01 on Jet Fuel Specifications, - The progress made in Section J01 includes but was not limited to: -A description of a generic Fischer-Tropsch derived product known as synthesized paraffinic kerosine (SPK) is being developed for use in blending jet fuel at levels up to 50% (by volume). This will be balloted for inclusion in the jet fuel specification (ASTM D1655 , Standard Specification for Aviation Turbine Fuels) when the…, Section J06 on Emerging Aviation Fuels, -, Section J06 is a new start-up group. Their actions at the meeting were: -Opened with a discussion of the current state of alternative turbine fuels. So far, synthesis gas derived hydrocarbons are the only alternative blend stream approved or nearly approved for use in jet fuel. Their approval resulted from the efforts of SASOL, which developed synthetic jet fuel blend stocks back in the 1990s and…, Section J04 on Additives and Electrical Properties, -, Topics discussed included:, -During the session it was agreed to ballot for membership approval the new Standard Practice Guideline for the Qualification and Approval of New Aviation Turbine Fuels and Fuel Additives, as a replacement for the current words in ASTM D4054 (same title). This guideline provides a framework for the qualification and approval of new fuels, including alternative fuels and new fuel additives for use…

New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…
