摘要：A hardness tester includes a correlation memory storing correlation data whichassociates hardness of a standard reference sample based on dimensions of anindentation formed by pressing an indenter into a surface of the standard reference

sample, and hardness of the standard reference sample based on test force anddepression amount during formation of the indentation in the standard referencesample. A CPU measures the test force and depression amount during formation of theindentation in a measured sample; calculates an estimated value of the hardness of themeasured sample based on the measured test force and depression amount; and

calculates the hardness of the measured sample based on the calculated estimated valueand the correlation data.
