Dye penetrant inspection services can be successfully performed on products made of non-porous materials such as metal and glass. The component under test next undergoes a visual inspection to identify any leaks or surface imperfections. It is a common method used to check for deficiencies in welds, pipes, bars and other materials. Scope : 1.1 This procedure shall be followed for the examination of both ferromagnetic and non-ferromagnetic Liquid penetrant testing is a versatile nondestructive test method used for the detection of OPEN TO SURFACE DISCONTINUITIES in a wide variety of solid, non-porous materials. Any PT inspection on elevated temperature (temperature other than 4C to 52C), should have special qualification on the Consumables. The technique is based on the ability Apabila kita melihat ke belakang, sejarah uji penetrant ini bermula ketika awal tahun 1900 an metode kapilaritas digunakan dalam industri perkeretaapian untuk memeriksa komponen mesin pada lokomotip, ketika itu uji penetrant masih disebut dengan metoda "minyak dan kapur", hal ini dikarenakan untuk pengaplikasiannya menggunakan minyak lumas hitam dan bubuk kapur. The test object or material is coated with a visible or fluorescent dye solution. The basic principle of liquid penetrant testing (PT) is capillary action, which allows the penetrant to enter in the opening of the defect, remain there when the liquid is removed from the material surface, and then re-emerge on the surface on application of a developer, which has a capillary action similar to blotting paper. Liquid penetrant testing has the following disadvantages: Extensive, time-taking pre-cleaning criticalsurface contaminants can mask defects Sensitive to surface-breaking defects only Direct connection to the surface under test necessary Works on relatively non-porous surface materials only No depth sizing Multi-process testing procedure The American Society of Mechanical Engineers (ASME) publishes standards for the use of liquid dye penetrant testing, including ASME Section V, Section VIII Division 1, ASME B31.1 & ASME B31.3 .

Liquid dye penetrant testing is a common nondestructive testing (NDT) method that is used to detect discontinuities in a variety of engineering materials. (c) Surface tension. LPT is based on capillarity or capillary attraction, where a liquid is able to flow into narrow spaces without the assistance of - or even in opposition to - external forces such as gravity. It can detect surface-breaking flaws such as cracks, laps, porosity. Liquid penetrant inspection (LPI) is a cost-effective and non-destructive way of locating surface defects such as cracks, porosity, laps, seams, and other surface irregularities. After cleaning, a penetrant material is applied to the part's surface where it remains, or dwells, for a specific length of time. After a dwelling time, the excess penetrant is removed, any remaining penetrant in the voids will flow back out, exposing the indication. Liquid penetrant testing can be performed on any solid, non-porous material, such as metals, ceramics or plastics. Liquid Penetrant testing Questions Levl 1&2.
