A proposed ASTM International standard will provide best practices for companies that coat pipe with porcelain enamel (glass) lining. Such lining has been used in municipal wastewater, sewage treatment and other water-related industries since the 1960s. Subcommittee B08.12 on Materials for Porcelain Enamel and Ceramic-Metal Systems is developing the standard. Porcelain enamel lining acts as a…, ASTM Committee B08 on Metallic and Inorganic Coatings Next Meeting:, Nov. 18-19, 2015, November Committee Week, Tampa, Fla., Media Inquiries:, Nathan Osburn, tel +1.610.832.9603; nosburn@astm.org, Technical Contact:, Charles Baldwin, Ferro Corp., tel +1.216.875.6204; charles.baldwin@ferro.com, ASTM Staff Contact:, Diane Lake, tel +1.610.832.9661; dlake@astm.org Release #9827 ###

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…
