Piston ring/liner interface can contribute as much as half the total friction loss in internal combustion engines, with the resulting wear leading to reduced energy efficiency and raised emissions. A new ASTM International standard provides a method to more accurately measure small amounts of wear on curved piston ring segments and their counterfaces after lubricated bench-scale testing. “Coupled…

ASTM International Committee F38 on Unmanned Aircraft Systems (UAS) was recently requested by the Federal Aviation Administration to assist with the development of industry consensus standards to support the integration of small unmanned aircraft systems (sUAS) into the U.S. national airspace system (NAS). Following a model that was successfully used for the integration of light sport aircraft…

The U.S. Federal Aviation Administration has selected ASTM International Committee F38 on Unmanned Aircraft Systems to develop industry standards for small unmanned aircraft systems. These standards will allow sUAS to file and fly missions in the national airspace alongside manned aircraft. According to Rocklin Gmeiner, director, federal/civil programs, Raytheon, and chairman of F38.01, one of…, Technical Contact:, Rocklin Gmeiner, Raytheon Co., Arlington, Va., Phone: 703-284-4308, regmeiner@raytheon.com, ASTM Staff Contact:, Daniel Schultz, Phone: 610-832-9716; dschultz@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8507/Feb2010

ASTM International Committee D03 on Gaseous Fuels invites all interested parties to participate in their standards developing activities. Proposed new standards currently being developed by subcommittees within D03 include ASTM WK24874, Test Method for the Determination of Moisture Vapor Concentration in Natural Gas and by Tunable Diode Laser Spectroscopy (TDLAS), and ASTM WK24875 , Practice for…, Tunable Diode Laser Spectroscopy, The proposed new standard, ASTM WK24874 , is being developed at the request of several gas companies that use TDLAS analyzers for the measurement of moisture in natural gas. While TDLAS has become a popular type of gas analysis, no specific standard currently exists for its use. ASTM WK24874 is under the jurisdiction of Subcommittee D03.12 on On-Line/At-Line Analysis of Gaseous Fuels. According…, Siloxanes, While biofuel from landfills and sewage digestion has been used as fuel for local gas turbine engines, it is necessary to hold the content of siloxanes within the fuel down to 50 parts per billion. Siloxanes that can coat the turbine under working conditions are converted to an abrasive silicone dioxide coating that greatly reduces the lifetime of the engine. ASTM WK24875 is currently being…
