ASTM WK47046

    Revision of C1670 / C1670M - 13a Standard Specification for Adhered Manufactured Stone Masonry Veneer (AMSMV) Units

    (What is a Work Item?)

    Active Standard: C1670 / C1670M - 15

    Developed by Subcommittee: C15.03 | Committee C15 | Contact Staff Manager


    1. Rationale

    ASTM C1670 requires compressive strength testing on a mix design, and places limits on when new testing is triggered (such as when materials change). Manufacturers produce a wide variety of unit shapes and sizes from that mix design, and it is not required to test each individual strength for shape. Since this concept can be confusing, it is proposed here to add a new note to the section on compressive strength that clarifies this.
