Prospect, IL Introduction C28 Advanced Ceramic Standards Standardization: Mechanical and physical properties of ceramic bodies can be difficult to measure correctly unless the proper Visit the C28 website ( http://www.astm.org/COMMIT/COMMITTEE/C28.htm ) to purchase C28 standards or join the C28 committee. Tangible Benefits techniques are used. The Advanced Ceramics Committee of ASTM, C-28, has developed dozens of Monolithics Composites, Coatings, Porous Ceramics Comparisons Among Authors consensus test standards and practices to measure various properties of a ceramic monolith, composite, And Helping to Interpret Data C 1557 or coating. The standards give the “what, how, how C 1468 Filament C 1161 Flexural strength CFCC Tensile not, and why” for measurement of many mechanical, Tensile strength The Problem: C 1211 Flexural strength (High Temp) Trans thickness and C 1421 Fracture physical, thermal, and performance properties.

The C 1360 Cyclic fatigue C-28 Committee has involved academics, producers, ● Standardized Fracture Toughness and users of ceramics to write and continually update C 1424 Tests (C1421) insure correct comparisons of C 1322 Fractography Compression more than 45 standards since the committee’s different authors’ results -- C 1678 Fracture Mirror strength C 1341 CFCC Flexure strength inception in 1986.
