Metallic materials - Rockwell hardness test - Part 3: Calibration of reference blocks (ISO 6508-3:2015)
This part of ISO 6508 specifies a method for the calibration of reference blocks to be used for the indirect
and daily verification of Rockwell hardness testing machines, as specified in ISO 6508-2:2015.
Attention is drawn to the fact that the use of hard metal for ball indenters is considered to be the
standard type of Rockwell indenter ball. Steel indenter balls can be used only when complying with
ISO 6508-1:2015, Annex A.
