Leeb hardness test blocks are used to check Rebound Hardness Testers.
For this purpose, the instruments are set to the material steel/cast steel. If the measured values are outside the permissible tolerance, the cause is often due to impurities in the impact device or a defective impact body.The test blocks can also be used for the calibration of equipment according to DIN EN ISO 16859 or ASTM A956.The HLD test blocks are also engraved with the hardness values in HLDL, HLD+15 and HLC.
