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 materials.Rockwell Hardness Test. Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). Used to test: Tungsten carbide. Rockwell B Scale. Used to test: aluminum, brass, and softer steels. Rockwell C Scale. Used to test: harder steels. There are other scales that are associated with a Rockwell superficial test. These scales use a lighter loads and shallow impressions to perform the test. These are used on testing very thin metals.

Indentation hardness tests compose the majority of processes used to determine material hardness, and can be divided into three classes: macro, micro and nanoindentation tests. [2] [3] Microindentation tests typically have forces less than 2 N (0.45 lb f). Hardness, however, cannot be considered to be a fundamental material property.
The Shore A hardness scale is widely used in the polymer and plastics industry to characterize the hardness of various materials. Manufacturers use durometer testing as a quality check for manufactured products. For example, silicone hardness or rubber hardness can easily be measured and evaluated against manufacturing standards. Common hardness testing methods are introduced below. Rockwell Hardness. This method tests the hardness of steel parts by applying loads to parts via either a tungsten carbide ball or a spheroconical diamond indenter. A part’s testing surface and seating surface must be properly prepared prior to testing.
