Calibrated Rockwell hardness reference blocks
Euro Products manufactures calibrated Rockwell hardness reference blocks for routine verification and calibration of hardness testers. Select the load or scale, the nominal hardness value and the certificate; the options narrow automatically to the combinations available.
15 standard Rockwell scales, including HRA, HRB and HRC, with available nominal values from 3 to 126 depending on the selected scale.
Euro Products reference blocks are manufactured from carefully selected materials, heat-treated, precision-ground and lapped to provide stable, repeatable hardness values. Each block is calibrated using certified calibration machines.
Certificate
- UKAS – UKAS certificate to BS EN ISO 6508-3 and ASTM E18.
- EURO – traceable laboratory certificate (non-UKAS).
The selected nominal value identifies the block you are ordering; the calibrated value and uncertainty of measurement are stated on the supplied certificate.
Block size
64 mm diameter × 15 mm thickness.
