In light of COVID-19 (coronavirus) and ongoing safety concerns for members and staff, ASTM International announced today that all previously scheduled in-person May standards development meetings (including independent meetings) have been canceled. Earlier this month, ASTM International announced the cancellation of all April in-person meetings . These decisions were based on several factors,…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org Release #11001 ###

ASTM grain size is a property written into many specifications for metals, with finer grain sizes generally indicating better mechanical properties, such as formability. While measuring certain materials for such properties can be difficult, electron backscatter diffraction can provide precise determinations as well as give information on grain size distribution and statistics. A new ASTM…

A recent revision to ASTM International standard E384 , Test Method for Knoop and Vickers Hardness of Materials, expands the range of its coverage. The standard is under the jurisdiction of Subcommittee E04.05 on Microindentation Hardness Testing, part of ASTM International Committee E04 on Metallography. The revision incorporates ASTM E92 , Test Method for Vickers Hardness of Metallic Materials…

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…

Ceramic and glass companies, as well as universities and government laboratories, will be the primary users of a new ASTM standard that allows for the flexural strength determination of components made in a round shape or after finish machining with minimal waste. The standard, ASTM C1684 , Test Method for Flexural Strength of Advanced Ceramics at Ambient Temperature-Cylindrical Rod Strength, was…
