Non-Destructive Testing (NDT) is a process used across industries to inspect materials without causing any damage. It ensures the quality of industrial components, assemblies, and structures, detecting defects that could lead to costly failures or jeopardize lives and machinery.

There are five primary NDT methods: Ultrasonic Testing (UT), Liquid Penetrant Testing (PT), Magnetic Particle Testing (MT), Eddy Current Testing (ET), and Radiographic Testing (RT). Radiographic and Ultrasonic Testing is employed for internal defect detection, while Magnetic, Penetrant, and Eddy Current Testing are suitable for surface and near-surface defects. Other specialized NDT methods, such as Acoustic Emission, Leak Testing, Visual Testing, Strain Gauging, Thermography, and Concrete Testing, cater to specific applications. Advanced techniques like Digital Radiography, Phased Array Ultrasonic Testing, and Computer Tomography are emerging in the industry.

NDT technology benefits a wide range of industries including Power Generation, Aerospace, Chemical, Heavy Mechanical Fabrication, Automobiles, Oil and Gas, Ship Building, Foundries, and Civil Engineering. By improving the quality, reliability, and safety of components, products, and structures, NDT plays a crucial role in ensuring both human and industrial safety.

To effectively utilize NDT technology, it is essential to develop well-qualified NDT professionals and establish accredited NDT laboratories equipped with the necessary facilities.

In civil engineering, the application of NDT for testing concrete structures is particularly crucial, given the increasing number of construction projects. However, there is a need to develop a planned program to train qualified personnel for conducting NDT inspections on concrete structures. This will optimize the utilization of NDT technology in the civil engineering sector.

 

Inspection Body of National Centre for Non-Destructive Testing

The Inspection Body of the National Centre for Non-Destructive Testing (NCNDT) focuses on functional testing rather than analytical testing. It conducts inspections both in-house and on-site at industrial and construction sites, ensuring the integrity and conformity of items, products, structures, and assemblies.

Operating in accordance with international standards, codes, and specifications such as ASTM/ASME and BS Standards, the Inspection Body offers inspections in six main disciplines: Radiographic Testing (RT), Ultrasonic Testing (UT), Magnetic Particle Testing (MT), Eddy Current Testing (ET), Liquid Penetrant Testing (PT), and Concrete Testing (CT). Additionally, it provides services in Digital Industrial Radiography (DIR), Phased Array Ultrasonic Testing (PAUT), Thermographic Testing (TT) and instrument calibration and maintenance (IC&M).
