How to do a Rockwell Hardness Test
Performing a Rockwell hardness test with the ATI RS hardness tester is fast and fully automated. The operator only needs to:
- Place the sample securely on the anvil
- Press the START button
- Wait for the hardness test result to be displayed
During the test, the motorized hardness tester automatically performs all phases of the Rockwell method: application of the preliminary test force, application of the main test force, controlled dwell time, release of the main force, and final depth measurement under the recovery force.
The measured Rockwell hardness value is shown clearly on the display and highlighted in green or red according to the preset tolerance limits, allowing immediate pass/fail evaluation for quality control and production environments.
How to do a Brinell or Vickers Hardness Test
Performing a Brinell hardness test or a Vickers hardness test with the ATI RS hardness tester is as simple as it is for Rockwell testing.
Brinell Hardness Test – HBWT (Depth Measurement)
In accordance with ASTM E103, the ATI RS measures the depth of indentation directly during the test cycle. After pressing the START button, the hardness value is calculated automatically and displayed on the screen.
Brinell HBW and Vickers Hardness Test – Optical Measurement
For Brinell HBW and Vickers hardness testing, the ATI RS performs a precise and controlled indentation on the test surface. To obtain the final hardness value, the operator measures the indentation using an external microscope, either manual or digital, and calculates the result according to the applicable standards.
Hardness Tester Main Features
Clamping System
The integrated clamping system ensures maximum stability throughout the entire hardness test, even on long or unstable samples. The open clamping hood keeps the indenter and test area fully visible for safe and accurate operation.
Ergonomics & Usability
Ergonomic hardness tester frame with increased height for improved operator comfort. The open design provides a clear, unobstructed view of the specimen and eliminates the need to drill the bench table for the elevating screw.
Touchscreen Control Panel
Modern touchscreen control panel with 120° rotation and retractable articulated arm for flexible positioning. The side-mounted design allows easy adjustment for optimal visibility and can be moved out of the way to create additional workspace when testing large components.
Software test settings
Fast and easy operation, with specimen and operator ID input. Automatic hardness correction compensates for convex cylindrical surfaces. Color-coded pass/fail results (OK/NOK) are displayed based on preset tolerances. Dark mode improves visibility and comfort.
Live hardness measurement
During testing, the complete hardness test cycle can be monitored in real time, with load-time diagrams, countdown for each loading phase, live indenter movement visualization, and clear indication of test force and indenter type.
Hardness results report
Clear test data reports showing each result with color-coded pass/fail status (OK/NOK) and converted values. Results can be edited or cleared, statistical data is available, and reports can be exported as TXT files via USB.
