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…

ASTM International, one of the largest voluntary standards development organizations in the world, today announced the formation of a new committee to develop standards for the evaluation of materials and products relative to the restriction of certain hazardous substances. Committee F40 on Declarable Substances in Materials will address issues that could have a devastating economic impact on…, Beginning the Standardization Process, On Oct. 15, 2004, representatives from the appliance, electric tool, electronic, laboratory, instrument manufacturing, and supplier sectors affected by RoHS legislation attended a planning meeting at ASTM International Headquarters. They agreed to hold an organizational meeting to discuss the creation of a new standardization activity on declarable substances. The organizational meeting occurred…, Participation Is Open, The development of standards within Committee F40 represents a chance to help the environment while constraining unnecessary compliance costs that may damage many sectors of the world economy. If you are part of the business sectors mentioned above, participation in F40 is in your economic interest. The next meeting of Committee F40 will take place May 26-27, 2005, at ASTM International…
