Dye Penetrant Testing (DPT) process:

• After the plates have been properly cleaned and dried.
• The plates are brought into the spray booth area where the dye gets sprayed on one side only.
• After the dye is applied the plates are stacked to allow the dye to work into the material.
• Plates are then moved to the dark room area where black fluorescent lights are used to identify the pin holes or cracks.
• All pin holes and cracks are marked with a black felt permanent marker.
• Dye is washed off.
• Plates are dried.
