2020 marks the continuation of the 4th decade of standards from ASTM Committee C28 on Advanced Ceramics.
With over 50 standards on test methods, practices, guides, terminology, and specification for advanced ceramics under its jurisdiction, Committee C28 is proud to hold its first meetings of the year in conjunction with ACerS on Jan. 25 and 26, 2020, at the Hilton Daytona Beach Resort in Daytona Beach, Fla. (Find more info on the C28 meeting, including a meeting schedule and registration details, right over here. Register for ICACC’20 here.)
ASTM standards are high-quality, technically-rigorous, full-consensus products. A number of these ASTM standards have been harmonized internationally as ISO standards (e.g., flexural strength, tensile strength, fracture toughness, Weibull parameters, and elastic constants for monolithic ceramics as well as tensile, compression and shear strength for composites).
Both ASTM and ISO standards have been used extensively by users in military, aviation, nuclear, and automotive applications for design, fabrication, quality control, and failure analysis.
An important aspect of C28 standards is their importance as an enabling supporting technology to assist advanced materials as an enabling technology in the development of new technologies. An example of the tangible benefits of standards are references to C28 standards in “ASME Boiler and Pressure Code Section III—Rules for Construction of Nuclear Facility Components.”
In addition, C28 standards are referenced with their use required in “CMH-17 Part C: Guidelines For Testing Ceramic Matrix Composites.” It is noteworthy that other ASTM standards, particularly specifications, reference and require C28 standards.
Examples include ASTM F2094 “Standard Specification for Silicon Nitride Bearing Balls” and ASTM F2393 “Standard Specification for High-Purity Dense Magnesia Partially Stabilized Zirconia (Mg-PSZ) for Surgical Implant Applications,” both of which mandate use of several C28 standards including test methods for flexural strength, elastic constants, and hardness as well as a practice on reporting Weibull parameters.
