Liquid penetrant testing is used primarily for detecting surface discontinuities. 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. After a dwelling time, the excess penetrant is removed, any remaining penetrant in the voids will flow back out, exposing the indication. EQUIPMENT Equipment includes a cleaner, penetrant and developer. An examination is administered at the end of the final day of courses. Liquid Penetrant Performance without Developer Part 3.
