  2. Rockwell hardness test - Wikipedia

    en.wikipedia.org/wiki/Rockwell_hardness_test

    The Rockwell test does not use any optical equipment to measure the hardness indention, rather all calculations are done within the machine to measure the indention in the specimen. [ 13 ] The equation for Rockwell hardness is H R = N − h ∗ d {\displaystyle HR=N-h*d} , where d is the depth in mm (from the zero load point), and N and h are ...

    en.wikipedia.org/wiki/Barcol_hardness_test

    The governing standard for the Barcol hardness test is ASTM D 2583. [4] 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.
