    Revision of C1499 - 15 Standard Test Method for Monotonic Equibiaxial Flexural Strength of Advanced Ceramics at Ambient Temperature

    (What is a Work Item?)

    Active Standard: C1499 - 19

    Developed by Subcommittee: C28.01 | Committee C28 | Contact Staff Manager

    C1499 on equibiaxial flexural strength testing of advanced ceramics was originally approved in 2002 and was revised/reapproved in Fall 2015. The standard has been has reached the beginning of its periodic mandatory review. A discussion at the January 2019 C28 Committee meetings indicated that rather than tryng to modify C1499 to be more amenable to testing glass plates, it would be more reasonable to pursue a joint effort with Committee C14 on glasses to develop a new equibiaxial flexure test standard for glasses. Therefore, in the meantime, C1499 will continue to be primarily focused on advanced ceramics. A recent review of C1499 identified some minor errors in two definitions which are submitted for revisions here.
