What is Penetrant Testing?

Penetrant Testing can also be referred to as Dye Penetrant Inspection (DPI) or Liquid Penetrant Inspection (LPI). It is a low cost inspection method used to reveal surface breaking defects, commonly used on non-porous materials such as metals, plastics or ceramics. LPI is used to detect casting, forging and welding surface defects, such as cracks, surface porosity or fatigues cracks on in-service components, by the bleed-out of a coloured or fluorescent dye from the said defect.

It utilizes a penetrating liquid which is applied to the surface to be tested and is drawn into any discontinuity present. The excess penetrant is removed and a developer powder is applied to the surface which assists in drawing the residual penetrant from the discontinuities, thereby revealing their location.

Courses available

IMechE Argyll Ruane offer Penetrant Testing NDT training courses in Levels 1, 2 and 3 in a range of central and employer specific internationally recognised standards such as PCN (BS EN ISO 9712), SNT-TC-1A, EN4179 and NAS410.

We are also able to offer refresher training to those students that are looking to re-certify, providing training on any theory or practical areas that may need to be revisited before sitting their examination.

Courses are delivered at the Engineering Training Centre in Sheffield, UK but can also be completed on-site at an organisation's premises or third party location depending on each individual circumstance.
