Definition of hardness test
Non-destructive hardness test is defined as the process of checking and testing of construction materials and their components.
In this process, the components are tested to their extent without destroying them.
This allows us to know about the toughness of the materials so that in the coming days whether they will be able to stay or not.
This process is also known as non-destructive evaluation (NDE).
This process of non-destructive hardness testing is used in the industrial level because in the industries, these products are manufactured in bulk quantities and the industries do not compromise on the quality of the products.
For example, as we hear that due to earthquake, a building turned into ashes.
Whereas, all other buildings are still standing in their positions.
This also depends on the quality of the materials.
Hardness test lets the manufacturers check the quality of the material so that in case of any low-quality material production they could remake it and increase its quality.
In this way, the popularity of the industry increases due to increase in the quality of the products.
Difference between hardness test and bending or stress test
This process of hardness testing is very different from the processes of bending or stress testing because in stress testing and bending processes, materials often break and are deformed whereas nothing such happens in non-destructive hardness testing.
Rather it provides us with more specifications of the materials rather than any other test.
It is expensive than the others and sometimes also results in the loss of products but the main reason why manufacturers prefer this process is the detailed specifications that it provides us about the product.
The famous industries that use this process are automotive industries, aerospace industries, construction material industries and more.
Some of its uses in these industries are to identify any cracks in the aircraft skin, checking the flaws of the surface of the pipes etc.
Other uses of this test
Nowadays this process is becoming popular for the research and development purposes.
It provides almost all-important information related to the product that is necessary in the field of research and development.
It uses the processes of ultrasonic, rebound, ultra-sonic contact impedance etc.
to produce testing to ensure the quality of the product manufactured by the industry.
Therefore, in order to avoid any incident every material from base needs to be checked.
This reduces the risk of collapsing of the product built or manufactured by the components.
