ASTM International Committee B02 on Nonferrous Metals and Alloys is currently working on a proposed new ASTM International standard for zinc alloys being used for spin casting. The proposed standard, ASTM WK30745 , Specification for Zinc Alloys for Spin Casting, is being developed by Subcommittee B02.04 on Zinc and Cadmium. According to Bernard Potts, president of Village Casting Inc., and a…

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…

Crimped wire termination connections are very common in electrical goods, including small and large appliances, heaters, power tools and ride-on toys. However, these items often fail when crimped wire termination connectors are improperly manufactured or inappropriately used. These failures often result in financial losses for the product user and/or manufacturer, as well as safety issues that…

A proposed new standard currently being developed by ASTM International Committee F01 on Electronics will prove to be useful to the tantalum sputtering target industry. The proposed standard, WK9490, Test Method for Reporting Crystallographic Orientation of Sputtering Target Materials, is under the jurisdiction of Subcommittee F01.17 on Sputter Metallization. "The tantalum sputtering target…
