ISO 6508-2 specifies two separate methods of verification of testing machines (direct and indirect) for determining Rockwell hardness by ISO 6508-1, together with a method for verifying Rockwell hardness indenters.

The direct verification method is used to determine whether the main parameters associated with the machine function, such as applied force, depth measurement, and testing cycle timing, fall within specified tolerances. The indirect verification method uses several calibrated reference hardness blocks to determine how well the machine can measure a material of known hardness.

ISO 6508-2 applies to stationary and portable hardness testing machines. The text of ISO 6508-2:2023 has been approved in Europe as EN ISO 6508-2:2023 without any changes.
