Calibration – Accredited
Calibration of hardness testers and direct or indirect verification of a chosen number of methods (hardness measure type and load area, e.g. HV 1 or HRC), is performed and documented in accordance with the locally applicable standard.
Predictable hardness testing quality is paramount in materials with stringent requirements. This can only be achieved with confidence using a hardness tester that is correctly maintained and that has been calibrated according to internationally accredited calibration standards.
