What is the hardness test?

There are certain properties of material that are precisely defined. Hardness is not one of them. The hardness test can assess several things such as the resistance of the material to bending, scratches, abrasion or cutting. These tests can be performed in many ways. Test methods generally depend on the type of material tested, such as mineral, metal or rubber.

is a field where the hardness test can refer to the assessment of the resistance of scratches. It is common for geologists to use hard objects to try to scrape rocks and minerals with unknown hardness. There is a scale known as a measure of Mohs, which extends from one to ten. The softest materials are evaluated at the lower end of the scale and the most difficult objects at the highest end.

The hardness test that uses the Mohs scale is considered to be a relative test. This is because information that is achieved about one material is related to the information of another. Relative tests are often insufficient because do not provide many IndiansŽivotná

The Rockwell hardness test is the one that is considered more accurate. This test also deals with scratches, but focuses more on enforcement than to confirm whether one item can scratch another. This test is more complex and uses different pressure levels. Because there are several measurable factors, this test provides specific numerical data.

The

Vickers hardness test is also engaged in inventory. Numeric data can also be achieved from this test. First, a diamond insertion is used to shake the item's surface. Then the force is divided by the enforcement area to create the result.

The

test that measures hardness in terms of elasticity is known as the hardness test of the folder. The results of this test are based on hardness units. The test is carried out by allowing a hammer with a diamond tip to fall on the test material. The hammer should be reflected to some extent. ThisOK determines hardness.

Some people try to convert results from one test to another or compare them. This can be done in some cases, but the results are unlikely to be accurate. This is because the factors that surround each test can be so different, so it is very difficult to precisely convert one set of numerical terms to another.

The decision which method of testing is best is often based on the material tested. Each method can have advantages and disadvantages. In some cases, more than one type of test may need to be performed on one item.
