Thank you for the indenters (diamond  cone 120 degrees). We recently got it and already tested it. Indenters  are good as we expected.

Repeatability and Error of Rockwell Test Blocks

Standardized Rockwell test blocks shall be used in the appropriate hardness ranges for each scale to be verified. These ranges are given in below table. Hardness measurements shall be made only on the calibrated surface of the test block.

 

Repeatability and Error of Rockwell Test Blocks

 

Note A: The user may find that high, medium and low range test blocks are unavailable commercially for some scales. In these cases one or two standardized blocks where available may be used. It is recommended that all high range test blocks for Rockwell scales using a ball indenter should be less than 100 HR units.

 

Note B: Appropriate ranges of standardized test blocks for the L, M, P, R, S, V, W, X, and Y scales shall be determined by dividing the usable range of the scale into two ranges, if possible.
