Rockwell hardness tester uses the most commonly used method across different continents to determine the hardness of materials.
Rockwell hardness tester is also used on plastics. The method used by the Rockwell hardness test is ISO 6508 and ASTM E18.
Rockwell hardness test indicates the permanent indentation depth caused by a load or force. Many industries use this hardness test since it is pretty easy to use and a fast method since it immediately indicates the hardness of material after force or load is applied.
How to Determine Rockwell Hardness Test
The hardness test through the Rockwell hardness test is carried out by applying a minor load, followed by a major load helping the material reach the total test load.
The major load is then held for a dwell time allowing elastic recovery; then, it is removed. The minor load stays in place to determine the reference position to help in determining the Rockwell hardness value of the material being tested.
