Hardness test blocks serve both for indirect testing and calibration of hardness testing machines, especially for daily verification of the hardness testing machines and thus they are indispensable for quality assurance in hardness testing to secure the correct tests. Our Vickers hardness reference blocks are available in the following sizes:
Vickers:30x30x6mm (Micro), 60x60x16mm (Macro)
Calibration: All hardness reference blocks are calibrated by a calibration laboratory according to DIN EN ISO 6507-3 or ASTM E92 and receive a DAkkS calibration certificate.
We provide comprehensive resources on metallographic analysis and material science. Explore topics ranging from sample preparation techniques to microscopic examinations.
