    Revision of C1716 / C1716M - 16 Standard Specification for Compression Testing Machine Requirements for Concrete Masonry Units, Related Units, and Prisms

    (What is a Work Item?)

    Active Standard: C1716 / C1716M - 19

    Developed by Subcommittee: C15.04 | Committee C15 | Contact Staff Manager

    Keywords

    Rationale

    Sections 4.5.2 and 4.5.3 give requirements for spacer plates and bearing plates. Similarly sections 4.5.4 and 4.5.5 give requirements for spacer blocks and bearing blocks. While technically correct these sections are redundant with other sections in the standard as written. Section 3.1.1 defines the term bearing being in direct contact with the specimen being tested. Section 4.9.6 requires all surfaces used in bearing to be hardened. Sections 4.5.2 through 4.5.5 can be greatly simplified.
