Selection Correct Test Force of Vickers Hardness Testing

The force selection criteria of Vickers hardness tester include the following points:

1. Test requirements: Select the force value of Vickers hardness tester according to the test requirements. If the hardness layer to be tested is deeper, a larger force value should be selected; if the hardness layer to be tested is shallower, a smaller force value should be selected.

2. Sample size: The size of the sample is also an important consideration for selecting the force value. If the sample is small, a smaller force value should be selected to avoid crushing the sample.

3. Load type: Vickers hardness tester has a variety of load types, such as body weight, load, pressurization, and even load. Different load types require different force values.

4. Test material: Different materials require different hardness, so it is necessary to select an appropriate force value according to the test material.

5. Reference standard: Select the force value according to the relevant reference standard or international standard.

In short, when selecting the force value of Vickers hardness tester, it is necessary to comprehensively consider factors such as test requirements, sample size, load type, test material, and reference standard to ensure the accuracy and reliability of the test results.
