WebDavid Von Rohr, metallurgical quality manager from Philadelphia Gear, demonstrates how to properly perform visible liquid penetrant inspection (also known as... Dye penetrant inspection (DP), also called liquid penetrate inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casti…
Step by Step Dye Penetrant Testing
WebMaterial and Methods: This was an in vitro intergroup comparative study, which consisted of 2 groups- Group I (Conventional acid etch sealant, Clinpro) and Group II (Self etching sealant, Prevent Seal). Out of 32 selected teeth 16 were used to study microleakage, with the help of dye penetration test using {\"o}vreb{\"o} and Raadal criteria. WebLiquid penetrant testing can be applied to any non-porous clean material, metallic or non-metallic, but is unsuitable for dirty or very rough surfaces. Surface cleaning is a vital part of the penetrant testing technique. The method can be manual, semi-automatic or fully automated.

WebThe dye solution uses a 3% surfactant as opposed to a 0.5% in the porous package method. The inspection involves use of an absorbent material, which will provide evidence of dye staining. Test Method. Inject the dye penetrant into the package or along sealedge at a volume of at least 0.25 ml per 25 mm [1 in.] of seallength.
