Why Is Non-Destructive Testing Needed?

Non-destructive testing is a term used to refer to a group of scientific methods of examination which are employed in the evaluation of material properties. Non-destructive testing techniques are unique in this regard because they test materials without causing any damage. On the other hand, destructive testing tests for specimen failure: the object undergoing evaluation loses its ability to function as intended following a test. 

Non-Destructive Testing VS Destructive Testing Applications 

In situations where components or structures must continue to function after being tested for structural integrity, non-destructive testing is used. In contrast, in continuous systems where large quantities of products are manufactured, not every piece of material needs to undergo testing and destructive testing is appropriate. A sample can be tested for various properties such as tensile strength, bend capacity, impact resistance or fire resistance to gain knowledge about its physical properties. If a product fails a destructive test then the entire batch of products manufactured to the same specifications must be discarded. 

Why Is Non-Destructive Testing Needed? 

Before non-destructive testing was conceived, destructive testing was used to ensure batches of components were manufactured to safety standards. The logic was that destructive tests should provide an indication about whether a sample of parts was fit to endure the stresses placed on it during operation. However, despite destructive testing taking place, several incidents occured where components were destroyed during operation and led to loss of property and human life. As a consequence, non-destructive testing methods were developed to eliminate such failures without damaging the product in use. 

When Is Non-Destructive Testing Used? 

In today’s industry, almost all critical product components require regular non-destructive tests during their lifecycle. High-pressure valves, pressure valves, oil pipelines, aircraft industries, automotive industries and railways are just some examples of when non-destructive testing is used. 

Benefits of Non-Destructive Testing 

The benefits of non-destructive testing are manifold. No damage to the part being tested is sustained and therefore it remains useful. Non-destructive testing can be carried out at any time in the product’s lifecycle: raw materials, semi-finished or finished components can be tested with equal measure of effectiveness. Non-destructive testing also offers very comprehensive testing and can be used to locate both surface and internal flaws. Finally, non-destructive testing allows manufacturers and engineers to ensure worksites and materials are compliant with regulation designed to ensure their safety.
