Air permits from regulatory agencies, such as the U.S. Environmental Protection Agency (USEPA), often require the measurement of a plume's opacity as the plume is emitted from a stationary point source (for example, smokestacks) in the outdoor ambient environment. While such opacity is often visually measured by human observers as “certified smoke readers,” an opacity measurement method using…

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.…
