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 ...
The Rockwell hardness test can be conducted on different types of hardness testers. [12] Benchtop hardness testers can be found either in a digital or analog model. Digital models utilize a digital display whereas the analog models display results on a dial on the machine. Other testers are portable. [citation needed]

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 .
Urban skates Hockey skates. Inline skates are boots with wheels arranged in a single line from front to back, allowing a skater to roll along on these wheels. Inline skates are technically a type of roller skate, but most people associate the term roller skates with quad skates, another type of roller skate with a two-by-two wheel arrangement similar to a car.
Quad roller-skating racing is the precursor to the popularity and acclaim received by competitive racing on in-line skates. Up until 1991, all World Championships were held on quad skates. Most events at the 1992 World Championships were specific to quads, however, some events were classed as "open" giving the athlete the option of choosing ...
Nope, Rockwell can use either cone or ball depending on which scale you are doing. For example, HRC scale uses a cone but HRB uses an .062 ball. This is already explained in the article (look in the table in the Scales and values section). — ¾-10 17:48, 24 February 2014 (UTC)
Barcol hardness is measured on a scale from 0 to 100 with the typical range being between 50B and 90B. A measurement of 60B is roughly equivalent to a Shore hardness of 80D or a Rockwell hardness M100. [4] [6] As defined in ASTM D 2583 the scale divisions from 0-100 should each indicate a depth of 0.0076 mm or the equivalent 0.0003 inches. [7]
