UCI hardness test blocks are developed especially for the verification and calibration of UCI hardness testers (like the alphaDUR mini) and meet the requirements of the DIN 50159 and ASTM A1038 regarding the diameter, wall thickness and e-modulus.
The test blocks are available from app. 240 HV to app. 850 HV (below 240 HV on request) and can be calibrated with test loads from HV0,3 to HV10 resp. Rockwell C (HRC). A traceable certificate in german and english language, according to ISO and ASTM is issued with every test block.
A wooden case for storing the blocks is available separately.
