Roche test principle:
At the beginning of the experiment, the pressure head of the testing machine is placed on the specimen, an initial test force is applied, and a reference point measured by the displacement measurement device is established. Because the initial test force causes the indenter to press into the specimen, the smoothness or irregularity of the surface will not affect the test. Next, the testing machine applies the main test force, which is larger and enters the specimen deeper. Then, the main test force is removed while maintaining the initial test force. At this time, the testing machine measures the depth of the indentation relative to the established reference point. The straight-line depth of dents is the basis of Rockwell hardness values. A shallow indentation depth only indicates a higher material hardness, while a relatively deep indentation depth indicates a softer material hardness.
HRC A=100-n1-n0 0.002
HRB=130-n1-n0 0.002
In the formula: n0- the depth at which the indenter is pressed into the specimen under the initial test force F0
N1- The depth at which the indenter is pressed into the specimen while applying the total test force F and removing the main test force F1, while still maintaining the initial test force F0.
