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…

The additive manufacturing industry will greatly benefit from a new ASTM International standard that will allow computer- aided design programs, scanners and 3D graphical editors to communicate with 3D printers and additive manufacturing equipment. The standard will answer the growing need within the industry for a standard interchange file format that can work with features such as color,…

A long-standing need to standardize terminology within the additive manufacturing industry has now been met with a new ASTM International standard, ASTM F2792 , Terminology for Additive Manufacturing Technologies. The new document is the first approved standard under the jurisdiction of ASTM Committee F42 on Additive Manufacturing Technologies, which was formed in 2009. Terry Wohlers, principal…, Technical Contact:, Terry Wohlers, Wohlers Associates Inc., Fort Collins, Colo., Phone: 970-225-0086; tw@wohlersassociates.com, ASTM Staff Contact:, Pat Picariello, Phone: 610-832-9720; ppicarie@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8426/Dec2009

Flow characteristics of fine metal powders are important in filling dies for pressing of powder metallurgy compacts, which are later sintered and sometimes machined into finished parts. The flow rate, as measured by a new ASTM standard, determines the flow necessary for a precise quantity of powder to be introduced into the die. The new standard, B964 , Test Methods for Flow Rate of Metal Powders…
