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…

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.…

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…

Two recently approved ASTM International standards provide user-friendly tests for properties of sintered metallurgy products. The new standards, developed by Subcommittee B09.04 on Bearings, are ASTM B962 , Test Methods for Density of Compacted or Sintered Power Metallurgy (PM) Products Using Archimedes’ Principle, and ASTM B963 , Test Methods for Oil Content, Oil-Impregnation Efficiency and…

While drug products must be tested for chemical and physical stability in their market packages, the testing process can be long and expensive. A proposed new ASTM International standard under the jurisdiction of Committee D10 on Packaging will provide a quick and accurate method to minimize the necessary package testing. The proposed standard, WK21601 , Test Method for Measuring Water Vapor…

The use of rolling devices can provide a means to evaluate the adhesion of weather seals, for quality control in new installations, general evaluation of existing installations, and the investigation of water and air leakage through building enclosures. In order to better facilitate the use of rolling devices, ASTM International Committee C24 on Building Seals and Sealants is developing a…
