Liquid (Dye) Penetrant Testing (DPT/PT)

Liquid (Dye) Penetrant Testing (DPT/PT)

Liquid penetrant testing is applied to any non-porous clean material, metallic or non-metallic, but is unsuitable for dirty or very rough surfaces. Penetrants can contain a dye to make the indication visible under white light, or a fluorescent material that fluoresces under the suitable ultra-violet light. Fluorescent penetrants are usually used when maximum flaw sensitivity is required.
