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 Committee F24 on Amusement Rides and Devices will celebrate its 30th anniversary this year, marking its significant contributions to the global amusement industry. ASTM is one of the largest voluntary standards development organizations in the world., F24 Standards: The Foundation for Safe Fun, Since 1978, ASTM Committee F24 has developed the standards that are the underpinning of safety for amusement rides and attractions around the world. During the past three decades, Committee F24 has contributed a comprehensive range of standards that cover design, manufacturing, maintenance, inspection and operations across traditional amusement rides, specialty rides and attractions, and water-…, F24: Global Experts Developing Internationally Accepted Standards, ASTM Committee F24 brings together global amusement industry stakeholders in a best-in-class standards development forum. Today, F24 comprises approximately 500 professionals from 23 countries across North America, South America, Europe and Asia. F24 members include ride designers and manufacturers, engineers, technicians, regulators, inspectors, park owners and operators, consumer advocacy…, Supporting Ride Innovation and Amusement Growth, As new categories of amusement rides have been introduced and grown in popularity, ASTM Committee F24 has kept pace by addressing emerging requirements for standards. In the last several years, new F24 subcommittees have been formed to address growth in areas such as water rides as well as specialty attractions like go-karts, inflatable amusement devices and bumper boats., A Model of Industry Cooperation, To help to establish worldwide consistency in major areas of ride safety standards, ASTM Committee F24 works in close partnership with other representative organizations of the global amusement industry, such as the International Association of Amusement Parks and Attractions (IAAPA). ASTM F24 and IAAPA bring together representatives from industry and standards bodies from around the world for…

Sampling is a difficult but essential part of the coal production process. ASTM International Committee D05 on Coal and Coke hopes to streamline that process with the publication of new standard D 7256/D 7256M, Practice for Mechanical Collection and Within-System Preparation of a Gross Sample of Coal from Moving Streams. Practice D 7256/D 7256M is under the jurisdiction of Subcommittee D05.23 on…

The rapid growth and variety of rides being developed within the water park industry has created a need for new standards to regulate the design and installation of water slides. While individual states within the United States had created rules and guidelines for water slides, these often varied greatly from each other. A new standard developed by ASTM International Committee F24 on Amusement…

Most of the coal burned in the United States contains only trace amounts of chloride and fluoride. However, due to the increasing regulation of these compounds for clean air initiatives, being able to measure even small amounts of chloride and fluoride in coal has taken on a greater importance than ever. Recognizing this, ASTM International Committee D05 on Coal and Coke has begun to develop a…
