- Rockwell hardness | HR
- en
- Definition degree of hardness of a material, based on its resistance to identation, and determined by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload Reference "COM-EN, based on:Wikipedia > Rockwell scale. http://en.wikipedia.org/wiki/Rockwell_hardness [29.8.2013]"
- Comment There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, where A is the scale letter.
