Verification and calibration of testing machines Executive summary Method of verification of testing machines for determining Vickers hardness.
The hardness ranges should be chosen, when possible, to replicate the hardness levels most commonly tested when using the specific test forces. This part of ISO is also applicable to portable hardness testing machines.
If a testing machine is also to be used for other methods of hardness testing, it needs to be verified independently for each method.
