ASTM International’s wear and erosion committee ( G02 ) has released a new standard that provides a test method for measuring friction and adhesive wear properties of lubricated and nonlubricated materials using the twist compression test (TCT). The new standard (soon to be published as G223) can be used to “rank combinations of surfaces in their resistance to adhesive wear. This can be useful…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Jennifer Tursi HER , tel +1.610.832.9653; jtursi@astm.org Release #11697 ###

A new ASTM International test method could play an important role in supporting next-generation nuclear power through advanced ceramics, which are used to make many parts of nuclear reactors. According to ASTM International member Michael Jenkins, the new standard harmonizes many test methods developed over the years to measure the stress-strain behavior and strength of composite tubes subjected…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, James Farrell, tel +1.610.832.9661; jfarrell@astm.org Release #10482

A new standard will help test technology that is used in many electronic devices. According to ASTM members Lin Tingyu (National Center for Advanced Packaging) and Hi Jinjiang (Grikin Advanced Materials Co. Ltd.), the new standard will provide a baseline of quality, reliability, and process for manufacturers of “sputtering targets,” which are often used for thin-film deposition, etching, and…, ASTM Committee F01 on Electronics Next Meeting:, January 31, 2017, January Committee Week, Norfolk, Va., Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Technical Contact:, Lin Tingyu, National Center for Advanced Packaging, Wuxi, Jiangsu province, China, tel +1.535.805.3318; tingyulin@ncp-cn.com, ASTM Staff Contact:, Kelly Paul, tel +1.610.832.9745; kpaul@astm.org Release #10163

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…

ASTM Committee G02 on Wear and Erosion is including a field trip in the plans for its Dec. 8-9 meeting in Jacksonville, Fla. Committee members will be visiting the Tribology Laboratory in the mechanical engineering department at the University of Florida in Gainesville. The Tribology Laboratory is actively involved in a wide variety of tribological research and tribology education projects. The…

New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…
