Is particularly well suited for detecting surface cracks but can also be used to make electrical conductivity and coating thickness measurements. Here a small surface probe is scanned over the part surface in an attempt to detect a crack. Dye penetrant inspection (DPI), also called liquid penetrant inspection (LPI), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials, but for inspection of ferrous components magnetic-particle inspection is preferred for its subsurface detection capability. LPI is used to detect casting and forging defects, cracks, and leaks in new products, and fatigue cracks on in-service components. DPI is based upon capillary action, where low surface tension fluid penetrates into clean and dry surface-breaking discontinuities. Penetrant may be applied to the test component by dipping, spraying, or brushing.
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 a visible indication becomes visible to the inspector. Inspection is performed under ultraviolet or white light, depending upon the type of dye used - fluorescent or nonfluorescent (visible). Penetrants are classified into sensitivity levels. Visible penetrants are typically red in color, and represent the lowest sensitivity. Fluorescent penetrants contain two or more dyes that fluoresce when excited by ultraviolet (UV-A) radiation (also known as black light). Since Fluorescent penetrant inspection is performed in a darkened environment, and the excited dyes emit brilliant yellow-green light that contrasts strongly against the dark background, this material is more sensitive to small defects.

Industrial X-Ray & Allied Radiographers (I) Pvt. Ltd. commonly known as IXAR was founded in 1969 and started its activities in a humble way in the field of Radiography, one of the Non Destructive Testing methods.
The hard work, sincerity and dedication put together have brought her to its present standing with the inclusion of all the NDT test methods under her wing. This includes test methods like Ultrasonic, Magnetic particle, Liquid Penetrant, Eddy current etc.
There is not a single project of typical nature in India for which IXAR has not worked and thus vast experience gained, is the base for its full confidence to undertake any challenging job irrespective of size and technical complexities.
26th January 1985 was the land mark day for the company when the office was shifted to a new building admeasuring 5000sq.ft floor space.
