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 F. Shore (1876-1936) 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]
Hardness (Shore A durometer) 30–95 Tensile strength (MPa) 7–21 Elongation: 100–600% Compression set B 20–60% Useful temperature range (°C) −50 to +160 Tear resistance: Fair to good Abrasion resistance: Fair to good Resilience: Fair to good Electrical properties Insulator
The article mentions there being twelve types of durometer scale, including an R scale, but this type is not present in the list below. Please include it or indicate why it is excluded. Thanks. 69.199.250.34 21:45, 17 August 2011 (UTC) There is also Shore B and Shore C used for foam materials.
There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale. Larger numbers correspond to harder materials. When testing metals, indentation hardness correlates linearly with tensile ...

The unit of hardness given by the test is known as the Vickers Pyramid Number (HV) or Diamond Pyramid Hardness (DPH). The hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units. The hardness number is determined by the load over the surface area of the indentation and not the ...
