This part of ISO 6508 specifies two separate methods of verification of testing machines (direct andindirect) for determining Rockwell hardness in accordance with ISO 6508-1, together with a method forverifying Rockwell hardness indenters.The direct verification method is used to determine whether the main parameters associated withthe machine function, such as applied force, depth measurement, and testing cycle timing, fall withinspecified tolerances. The indirect verification method uses a number of calibrated reference hardnessblocks to determine how well the machine can measure a material of known hardness.The indirect method may be used on its own for periodic routine checking of the machine in service.If a testing machine is also to be used for other methods of hardness testing, it shall be verifiedindependently for each method.This part of ISO 6508 is applicable to stationary and portable hardness testing machines.Attention is drawn to the fact that the use of tungsten carbide composite for ball indenters is consideredto be the standard type of Rockwell indenter ball. Steel indenter balls may continue to be used onlywhen complying with the Special HR30TSm and HR15TSm test for thin products of ISO 6508-1, .
