    Revision of C1552 - 12 Standard Practice for Capping Concrete Masonry Units, Related Units and Masonry Prisms for Compression Testing

    (What is a Work Item?)

    Active Standard: C1552 - 14

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



    WK47041

    1. Rationale

    The task group was requested to further clarify the method for verifying perpendicularity of capped specimens, as described in Note 12. It was felt that the description of the proper method for using the combination square could be confusing to the reader. This ballot attempts to make it easier to understand how to utilize this method, when verifying perpendicularity and includes a new Fig. 2 which shows an example of the notched square that is discussed in the note. In addition, the term combination square has been changed to carpenters square as this type of square has proven to be practical and sufficiently accurate for this task.
