Standard Test Blocks for Brinell Vickers and Rockwell Hardness Testing Machine
Hardness reference blocks are used for annual verification and calibration of hardness testing machines, and sometimes for overtaking of hardness scales on a hardness testing machine. That's why they are a necessary help of industrial Quality Management.
Only the use of high quality, precise hardness reference blocks calibrated to applicable standards can ensure the functionality and relative reliability and accuracy of measurement of a hardness testing machine.
The quality requirements for hardness reference blocks in respect of the necessary homogeneity, microstructure stability, uniformity of hardness, surface quality, are described in the corresponding international, european and national standards, and are easily exceeded by the Buderus blocks.
Iqualitrol supplies all types of hardness blocks in all ranges, just contact us once there is demand.
