Answer
PT stands for Penetrant Testing (also called dye penetrant or liquid penetrant testing). It uses penetrant and developer to reveal discontinuities that are open to the surface of a clean, non-porous material.
PT can suit non-magnetic materials such as aluminium and stainless steel, but it cannot reveal subsurface defects. Surface preparation, dwell time, excess penetrant removal, developer and lighting affect the result.
