Two inline skate wheels with different durometer – 85A and 83A Digital Shore hardness tester. The Shore durometer is a device for measuring the hardness of a material, typically of polymers. [1] Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer ...
Albert Ferdinand Shore (September 4, 1876 – January 17, 1936) was an American metallurgist and the inventor of the Shore durometer. He won the Elliott Cresson Medal. [1] Shore was born in New York City. He invented the first quadrant durometer in 1915 to measure the hardness of polymers and other elastomers. [2]
A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .

The Barcol hardness test is generally used on soft materials such as rigid plastics. It measures hardness based on indentation of a sharp point with a flat tip. The test is performed using a similar method and indentation device as that used to measure Shore D hardness, however the Shore D indentor has a round tip. [4]
Federal investigators found nearly a dozen children to be working dangerous, overnight shifts at Seaboard Triumph Foods' pork processing plant in Sioux City, Iowa, the Department of Labor announced.
Shore durometer hardness, used for polymers Barcol hardness test , for composite materials Tensile testing , used to obtain the stress-strain curve for a material, and from there, properties such as Young modulus, yield (or proof) stress, tensile stress and % elongation to failure.
