In .
The diamond indenter shall be free from surface defects (cracks, chips, pits, etc.) and polished to such an extent that no unpolished part of its surface makes contact with the test piece when the indenter penetrates to a depth of 0.3 mm for Rockwell hardness testing and 0.2 mm for Rockwell superficial hardness testing.How to use the Rockwell hardness test for quick hardness testing in the lab or production environment. Vickers Hardness testing (HV) . Hardness Tester Calibration & Certification Requirements Know the requirements of calibration of various hardness testers and successfully pass your next audit.II. Theory and Principle of the Rockwell Hardness Test. The Rockwell Hardness Test uses a depth-differential method to test for hardness. A predetermined minor load is applied to the test sample, and the depth measurement is taken. Then a major load is applied to the same spot, which creates a deeper indentation.
We offer calibration of the following Hardness Testers: Standard Rockwell Hardness Testers which include C, B, and A Scales.
