Penetrant Testing

Penetrant Testing (PT)

What is Penetrant Testing?

The method employs a penetrating liquid, which is applied over the component’s surface under examination and enters the discontinuity or crack.

Subsequently, after the excess penetrant has been removed from the surface, the penetrant that exudes or is drawn back out of the crack or discontinuity is observed.

Liquid penetrant testing can be applied to any non-porous clean material, metallic or non-metallic, but is unsuitable for dirty or very rough surfaces. Penetrants can contain a dye to indicate visible under white light or fluorescent material that fluoresces under suitable ultra-violet light.

Dye penetrant inspection is the one non-destructive testing method used extensively to evaluate the condition or quality. It is easily carried out, inexpensive and usually does not require any special equipment. It is used to reveal surface breaking flaws by bleed out of a coloured or fluorescent dye from the flaw.

This testing method can be applied to ferromagnetic and non-ferromagnetic materials; however, it is most commonly used in non-ferromagnetic components, for example, when magnetic particle examination (MT) is not practical.
