Dye Penetrant Testing(DPT): Defination, Principle, Procedure,types

WebPenetrant Dwell Time. Penetrant dwell time is the total time that the penetrant is in contact with the part surface. The dwell time is important because it allows the penetrant the time necessary to seep or be drawn into a defect. Dwell times are usually recommended by the penetrant producers or required by the specification being followed.
