Helium leak testing is a highly sensitive method used to detect small leaks in sealed systems, this method uses helium gas, a non-toxic, inert, and lightweight gas, which can easily penetrate even the tiniest leaks. The process involves introducing helium into the system (either as a pure gas or a mixture) and using a mass spectrometer detection technology to measure the concentration of helium around the system or in a vacuum chamber.

Trace gas testing for oxygen and water vapor is a non-destructive analytical method used to detect and measure extremely low concentrations of moisture (H₂O) in controlled environments, sealed systems, or gas lines. This testing is essential in industries where even minute levels of these gases can lead to oxidation, corrosion, contamination, or degradation of sensitive products or components.

Pneumatic gas testing is a non-destructive pressure testing method used to check the integrity, strength, and leak-tightness of sealed systems by filling them with a compressed gas, such as air, nitrogen, or helium, and monitoring for any pressure loss or leakage. This test is commonly used when systems must remain dry and free of liquids, such as in aerospace, medical devices, electronics, and high-purity gas systems. The process involves gradually increasing the internal pressure of a system to a specified value, holding it steady, and then observing for changes. Leak detection may be enhanced using soap solution, electronic sniffers, or bubble testing.

Magnetic Testing (MT) method used to detect surface and slightly subsurface discontinuities in ferromagnetic materials (like iron, nickel, cobalt, and their alloys). It works by magnetizing the material and then applying fine magnetic particles (either dry or suspended in a liquid) to the surface. When a flaw such as a crack or void is present, it disrupts the magnetic field, causing magnetic flux leakage. The magnetic particles are attracted to these leakage fields, forming a visible indication of the defect.

Liquid Dye Penetrant Testing (LPT) method used to detect surface-breaking defects in non-porous materials. It is based on the principle of capillary action, where a liquid dye penetrant is drawn into surface cracks or flaws. The process involves applying a visible or fluorescent dye to the clean surface of a component. After allowing time for penetration, the excess dye is removed, and a developer is applied to draw out the penetrant trapped in surface defects. This creates a visible indication of flaws such as cracks, porosity, laps, or seams.

Radiographic Testing (RT) is a method used to inspect the internal structure of a component by using X-rays or gamma rays. The technique relies on the ability of these high-energy electromagnetic waves to penetrate materials and reveal internal defects such as cracks, voids, porosity, inclusions, or weld discontinuities. A radiation source is placed on one side of the object, and a detector (like a film or digital sensor) is placed on the opposite side. Areas with defects absorb or scatter the radiation differently, creating a contrast image (radiograph) that shows the internal features and any discontinuities.
