Shore r scale

SpletThe Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters. http://www.carbidedepot.com/formulas-hardness.htm

However, most mold makers only deal with three of these: 00, A, and D. Despite the scales being different, a lot of them span across the same range. For instance, a Shore hardness of 95 on the A scale is the same as a 45 on the D scale. Shore 00 is the softest of the three.
