The purpose of ASME B107.56 is to define essential performance and safety requirements specifically applicable to the various tools covered herein. It specifies test methods to evaluate conformance to the defined requirements and indicates limitations of safe use. During the consolidation revision of ASME B107.400, Striking Tools, it was determined that since ASME B107.56 included both striking and struck tools with different applications than the other striking tools in ASME B107.400, it should revert to a stand-alone standard under separate cover. This is the first publication of ASME B107.56 since its inclusion in ASME B107.400-2008.
