    This ballot proposes replacing the requirements for the compression test machine in ASTM C1314 with reference to ASTM C1716, Standard Specification for Compression Testing Machine Requirements for Concrete Masonry Units, Related Units, and Prisms. This new standard was developed in ASTM Subcommittee C15.04 on Research with the specific goal of providing a single, more detailed standard for test methods in Committee C15 to reference. This has the benefits of providing consistent machine requirements throughout C15 and enabling testing labs to have a single machine standard to be understand. The development of C1716 included input from a wide variety of sources, including testing labs, material producers, and testing machine manufacturers. The development process was sensitive to current standards (such as ASTM C67, C140, and C1314) that contain machine requirements for masonry products, so to not exclude current machines as much as possible. A goal, however, was to develop more detailed requirements for machines, and base requirements on rational design as much as possible. Because of this, the standard contains more specific requirements than currently exist within ASTM C140. Please note that in a previous ballot cycle ASTM C140 (for sampling and testing concrete masonry units) approved a similar change to reference C1716 and remove the machine requirements from C140.
