  • Method and apparatus for testing hardness of homogeneous materials
    Patent number: 4250742
    Abstract: A powder-actuated apparatus for determining the hardness of various homogeneous materials wherein the determination may be made in a manufacturing facility, warehouse, or in the field. The apparatus ensures that a constant driving force will be delivered to a testing probe without the need to carefully control the energy input source for the apparatus. Thus, conventional cased or caseless powder charges can be used as the initial energy source for the apparatus.
