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. To certify your Standard Rockwell Hardness tester to the current revision of ASTM E18, you are required to have certified penetrators. If certified penetrators are not available, we can certify your tester to the previous .profiles. The Rockwell test is the most popular indentation hardness test and is used in a wide variety of applications.

Calibrating the Rockwell hardness tester. This video shows how to adjust a Rockwell Hardness tester.this tester uses the standard test method for rockwell and Superficial rockwell hardness testing per AStM e-18. 2.1.1 Basic Operation 1. turn power switch on (back of the tester). the display will read SeLF teSt 2. After a few seconds the display will change to show the scale and status, for example: HrC Set 3.The Rockwell hardness test is less affected by surface rough-ness compared to other methods such as the Vickers or Brinell tests. It can provide reliable hardness measurements even on surfaces with moderate roughness, making it a practical choice for a wide range of materials and surface conditions.
Verification should be performed by an accredited verifying agency and the report should follow and reference ASTM E18 Rockwell test method. Hardness testing is an important and useful tool in materials testing, quality control and acceptance, and performance of materials. . Rockwell Hardness Testing Calibration Kits;
The Rockwell hardness test method, as defined in ASTM E-18, is the most commonly used hardness test method. You should obtain a copy of this standard, read and understand the standard completely before attempting a Rockwell test. The Rockwell test is generally easier to perform, and more accurate than other types of hardness testing methods .
