When selecting a hardness tester for your application, it is important for you to consider the following:
A, Choose the correct test method based on the application.
Plan to use the highest test force and largest indenter possible. Consider the effects of the shape and dimensions of your test sample.
B, Verify the test results meet your requirements for accuracy and repeatability. There are significant differences between levels of performance within each classification of tester. A difficult job on one tester could be very simple and fast on another.
