Considerations when choosing a hardness tester

Writer:Anonymous   2020-02-24 17:00:34

When choosing a hardness timing for your application, be sure to consider the following:

Choose the right test method for your application.

Plan to use as high a test force and indenter as possible. Consider the shape and size of the test sample.

Answer the following key questions:

1. Does your test specify the specific hardness level to be used?

2. What is the material to be tested and is it suitable for the type of test method you are considering?

3. How big is the part, component or sample to be tested?

4. Is it difficult to reach the test point?

5. What is the test volume to be completed?

6. How accurate is your test result?

7. What is your budget?

8. What is the required return on investment and do you have a way to measure costs-reductions in output, output and operator efficiency?

9. What testing problems did your current method encounter?

10. What is the knowledge level of the testers?

Confirm that the test results meet your requirements for accuracy and repeatability.

Consider performing quantifiable data collection on how much error there is between the operator and the measurement system used.

There are significant differences between the performance levels in each test classification. The hard work of a tester can be very simple and fast. So while the test methods and hardness testers in the classification look similar, there are many features that can significantly impact productivity and accuracy. A good example of performance impact is demonstrated in a benchtop Rockwell hardness test system. All products can use larger anvils or jacks to handle medium-length parts, but they can often test large parts faster and more accurately than other bench testers that require external supports or fixtures. On the other hand, it is easier to use on small pieces.
