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.
