Technical parameters:
Test principle:
At the beginning of the test, the indenter of the testing machine is placed on the specimen, an initial test force is applied, and a reference point measured by the displacement transmission measuring device is established. Because the initial test force causes the indenter to press into the specimen, surface smoothness or irregularities will not affect the test. Then the testing machine applies the main test force. This larger force penetrates deeper into the specimen, and then removes the main test force while maintaining the initial test force. Currently, the testing machine measures the dent depth relative to the established reference point. The linear depth of the dent is the basis for the Rockwell hardness number. A shallow dent depth only indicates a higher hardness of the material, while a relatively deep dent depth indicates a softer material hardness.
