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…

Tribometers are used to assess the potential of humans to slip while walking on various surfaces. A new ASTM International test method will be used to provide a reference standard against which to validate and calibrate the performance of tribometers. ASTM F2508 , Practice for Validation and Calibration of Walkway Tribometers Using Reference Surfaces, has been developed by Subcommittee F13.10 on…

As the use of antimicrobial agents in both medical and consumer settings continues to grow, there is real concern that targeted and peripheral microbial populations will develop survival strategies that would make them harder to eradicate when found in disease or spoilage situations. According to J. Stephen Richards, a research fellow at Johnson & Johnson and a member of ASTM International…, ASTM Committee E35 Next Meeting:, April 11-14, 2011, April Committee Week, Anaheim, Calif., Technical Contact:, J.
