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 Committee G02 on Wear and Erosion is including a field trip in the plans for its Dec. 8-9 meeting in Jacksonville, Fla. Committee members will be visiting the Tribology Laboratory in the mechanical engineering department at the University of Florida in Gainesville. The Tribology Laboratory is actively involved in a wide variety of tribological research and tribology education projects. The…

ASTM grain size is a property written into many specifications for metals, with finer grain sizes generally indicating better mechanical properties, such as formability. While measuring certain materials for such properties can be difficult, electron backscatter diffraction can provide precise determinations as well as give information on grain size distribution and statistics. A new ASTM…

A new ASTM standard will be useful to slide and engine companies, as well as makers of bushing materials, in studies that involve the measurement of system friction forces. The new standard, ASTM G203 , Guide for Determining Friction Energy Dissipation in Reciprocating Tribosystems, was developed by Subcommittee G02.50 on Friction, part of ASTM International Committee G02 on Wear and Erosion.…

Being able to complement marketing claims in advertising and promotions with third-party certification or verification is important in any industry. A new ASTM subcommittee will be working on standards for such verification in the livestock and meat industry. The new subcommittee, F10.60 on Livestock, Meat and Poultry Marketing Claims, is part of ASTM International Committee F10 on Livestock,…

There has been a renewed interest in instrumental qualification and standardization by the fluorescence community over the last 10 years, driven by the increasing number of quantitative chemical assays that use fluorescence detection and the presence of regulations in some of these areas. After revising three test methods for fluorescence instruments, stakeholders decided that a standard guide…

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…
