Non-Destructive Testing (NDT) refers to the family of methods used to evaluate the structural integrity of a material, weld or component without causing any damage to it. Techniques such as radiographic testing (RT), ultrasonic testing (UT), magnetic particle (MT), liquid penetrant (PT) and visual testing (VT) can reveal cracks, porosity, weld defects and internal discontinuities while the part remains in service.
In sectors such as energy, petrochemicals, pressure vessels, pipelines and steel construction, NDT is a cornerstone of both operational safety and legal compliance. A discontinuity detected early significantly reduces the risk of serious failure, production loss or workplace accidents in the future.
The value of an NDT service is directly proportional to the competence of the personnel performing it and the accreditation framework within which the method is carried out. Certified personnel (for example under ISO 9712) and accredited laboratory processes ensure the reliability and international validity of the results obtained.

- Radiographic TestingA method in which X-rays or gamma rays are used to image internal voids, thickness and density variations of a material on a radiation-sensitive film.
- Ultrasonic TestingA non-destructive testing method that determines the location, size and type of discontinuities by making use of the reflections of high-frequency sound waves within the material.
- Magnetic Particle TestingA method based on the principle of inducing a magnetic field in the test piece, used to detect surface defects in ferromagnetic materials.
- Penetrant TestingThe most widely used non-destructive testing method, in which surface-breaking defects are detected with a visible or fluorescent dye solution.
