Penetrant Test atau juga disebut Penetrant Inspection Cair atau “Pengujian Penetran” (PT) adalah metode pemeriksaan yang diterapkan secara luas dan murah digunakan untuk menemukan permukaan yang terindikasi cacat di semua non-ferrous material (logam, plastik, atau keramik). Penetrant dapat diterapkan ke semua non-bahan besi dan bahan besi, meskipun untuk komponen besi magnetik-partikel inspeksi sering digunakan sebagai pengganti untuk kemampuan deteksi bawah permukaan nya. LPI digunakan untuk mendeteksi pengecoran, penempaan dan cacat permukaan las seperti retak rambut, permukaan porositas, kebocoran dalam produk baru, dan retakan pada saat pemasangan komponen.
