Course Penetrant Testing
This inspection method is applied to find deffects that have an open connection to the material’s surface. Although penetrant testing can be done on a wide variety of materials, it is mainly used on non-ferrous metals. Penetrant testing is based upon capillary action, where low surface tension fluid penetrates into clean and dry surface-breaking discontinuities. After adequate penetration time has been allowed, the excess penetrant is removed, a developer is applied. The developer helps to draw penetrant out of the flaw where an invisible indication becomes visible to the inspector. Inspection is performed under ultraviolet or white light, depending upon the type of dye used – fluorescent visible.
In this Penetrant Testing course, both inspection methods are taught: the variety using daylight as well as the one using ultraviolet light. MME Group offers courses for Penetrant Testing on Levels 1 and 2 in accordance with the international standards of the American Society for Non-Destructive Testing (ASNT) and Hobéon SKO (ISO 9712, formerly EN 473).
