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…

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 Subcommittee E34.50 on Health and Safety Standards for Metalworking Fluids has developed three new standards. Two of the recently approved ASTM standards cover aspects of water-miscible metalworking fluids, while the third concerns prevention of dermatitis in the wet metal removal fluid environment., Prevention of Dermatitis, Dermatitis is an inflammatory response of the skin to a chemical or physical agent. While redness, swelling and itching are typical signs of dermatitis, symptoms can be more severe as well. A new ASTM standard, ASTM E2693 , Practice for Prevention of Dermatitis in the Wet Metal Removal Fluid Environment, discusses dermatitis and its causes and presents a comprehensive approach to dermatitis…, Metalworking Fluids, Two new E34.50 standards address the detection of microbial contamination in metalworking fluids: ASTM E2657 , Test Method for Determination of Endotoxin Concentrations in Water-Miscible Metalworking Fluids, and ASTM E2694 , Test Method for Measurement of Adenosine Triphosphate in Water-Miscible Metalworking Fluids. Both ASTM E2657 and ASTM E2694 measure biological contamination in metalworking…, Participation Invited, The subcommittee is currently looking for participants for an interlaboratory study for ASTM E2657 and ASTM E2694 . “We plan to use a single set of MWF for both standards, so labs who are interested in either or both are welcome to participate,” says Passman. “A few labs will run both the ILS’s for both standards, while most will run one or the other.” Subcommittee E34.50 is part of ASTM…
