FAQ - Calibration of Hardness Testers

What is hardness tester calibration?

Hardness tester calibration is the verification and confirmation of its metrological characteristics by comparing measurement results with reference hardness specimens in accordance with established standards.

Which hardness methods do you calibrate?

We perform calibration of hardness testers using the Brinell, Vickers, Rockwell, and Shore methods within defined hardness ranges.

Which standards is calibration performed according to?

Calibration is performed in accordance with international ISO and ASTM standards, with the issuance of a calibration certificate according to ISO/IEC 17025.

How often should a hardness tester be calibrated?

The recommended calibration interval is once every 12 months, or more frequently depending on the intensity of use, operating conditions, and the company’s internal procedure requirements.

Do you calibrate portable hardness testers?

Yes, we calibrate both stationary and portable hardness testers, including digital and universal models.

What documents do you receive after calibration?

You receive an ISO/IEC 17025 calibration certificate, which contains measurement results, uncertainty, and information on metrological traceability.

Where is calibration performed?

Calibration can be performed in the laboratory or on the customer’s premises, by agreement and provided that the environment complies with standard requirements.
