Manufacturers and users of laser scanners used in 3D imaging will benefit from a new ASTM standard that helps evaluate their measurement performance. Specifically, the standard will help evaluate time-of-flight imaging systems, which determine measurements by detecting the reflected light from a scene illuminated by a modulated light source. The new standard is E2938 , Test Method for Evaluating…, Media Inquiries:, Nathan Osburn, tel +1.610.832.9603; nosburn@astm.org, Technical Contact:, Kamel S.

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…
