Penetrant Liquid Testing (PT - FPI)
The liquid penetrant is a product used in non-destructive testing of materials that allows you to highlight the shortcomings of structural integrity of a material.

The control method is based on capillary action of a low surface tension liquid, which place in contact with a clean, dry surface penetrates into any discontinuities present on it.
Piercing the liquid can be applied to the components to be tested by immersion, spray or brush. After an appropriate contact time (referred to as penetration time), the excess penetrant is removed and is applied to a detector or developer who favors the escape of the penetrant from discontinuities allowing formation of the indication that becomes visible to the inspector, under UV-A or visible light, depending on which are fluorescent penetrant employed or contrasting color.

Dye penetrant inspection is a particularly effective method
to highlight and find surface discontinuities of a material
