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…

While the use of digital evidence is fairly common in contemporary criminal investigation, there are still relatively few degree programs in computer forensics. A new standard developed by ASTM International Committee E30 on Forensic Sciences provides a road map for post-secondary institutions to develop degree programs in computer forensics. The new standard, ASTM E2678 , Guide for Education and…
