Liquid penetrant testing

Liquid penetrant testing is a basic and most commonly used method of NDT. It is used to detect material discontinuities that emerge on the surface of the item examined. The scope of discontinuities detected by penetrant testing includes: lapping, fatigue and corrosion cracks as well as a number of welding defects. Depending on the size and nature of discontinuities, we use fluorescent and coloured methods. To ensure high sensitivity and discontinuities detection, we use aerosol penetration sets for examinations. Liquid penetrant testing is performed stationary in our laboratory as well as during fieldwork directly on the object specified. Liquid penetrant tests are carried out by staff with Level 2 PT certificates according to ISO 9712 standard and the 97/23/WE EU Directive.
