2017 marks the beginning of the 4th decade of standards of 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 January 21 and 22, 2017—preceding ICACC’17—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’17 here.)
ASTM standards are high-quality, technically rigorous, full consensus products. Many 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 in military, aviation, nuclear, and automotive applications for design, fabrication, quality control, and failure analysis.
An important aspect of C28 standards is their importance in supporting advanced materials to enable 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 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.
