Scleroscope hardness test

Dynamic hardness test using a calibrated instrument that drops a diamond-tipped hammer from a fixed height onto the surface of the material being tested. The height of rebound of the hammer is a measure of the hardness of the material. The result is expressed as the Scleroscope hardness number.
