Conventionally processed powder metallurgy materials often exhibit open microporosity at the surface. While it is a natural part of the process, this microporosity can affect the measurement of surface finishes. To cover this and other issues that arise from measuring the surface finish of powder metallurgy, ASTM International Committee B09 on Metal Powders and Metal Powder Products has developed…

A new ASTM International standard provides information and criteria for estimating the thickness of oil on water using only visual clues. The standard, F 2534 , Guide for Visually Estimating Oil Spill Thickness on Water, was developed by Subcommittee F20.16 on Surveillance and Tracking to provide a consistent means of visual oil spill thickness detection. Subcommittee F20.16 is under the…
