This document specifies the method of verification and calibration of testing machines for determining Knoop hardness for metallic materials in accordance with ISO4545‑1.
A direct method of verification and calibration is specified for the testing machine, indenter, and the diagonal length measuring system. An indirect verification method using reference blocks is specified for the overall checking of the machine.
If a testing machine is also to be used for other methods of hardness testing, it will be verified independently for each method.
