(engineering)
An instrument used to determine the hardness of a material by measuring the height to which a standard ball rebounds from its surface when dropped from a standard height.

Scleroscope

 

an instrument for measuring the hardness of metals and other materials according to the height of the rebound of a hammer with a hard (diamond) tip falling from a specified height onto the surface of the body being tested. Hardness is measured on a scleroscope in arbitrary units proportional to the height of the hammer’s rebound. The Shore scleroscope is a well-known type used in many cases for testing large, solid steel objects having a high surface hardness when there are no portable instruments available to determine the Rockwell hardness.

The foams with PVC skins were measured on the Shore scleroscope hardness.
Shore scleroscope hardness, water absorption, and cone indenter hardness had a greater effect on segment wear than other rock properties [15].
The density of this material is 1180 kg/[m.sup.3] the tensile strength is 37 MPa and the elastic modulus under 100% tension is 3.2 MPa, and the shore scleroscope hardness is 80A.
Researchers have been interested in the relative hardness of materials for centuries, but the first formal test for mechanical hardness didn't appear until 1896, when a professor in England, Thomas Turner, invented a device called a scleroscope, which dropped a diamond-tipped weight against a material.
Early dynamic hardness testing featured a "Scleroscope," a machine invented in 1906 by A.
