Dye Penetrant/Capillary Testing – PT

The penetration / capillary test is a fast, economical and widely used non-destructive test method for detecting surface defects in all types of non-porous materials (metals, plastics or ceramics). The penetration test is based on the principles of capillary action in which the penetrant penetrates into the cavities on the surface of the test object.

It is carried out on a thoroughly cleaned test surface by applying a colored or fluorescent penetration fluid. After the specified time of action, the exceeded penetrant is removed, and the developer is applied. Once the developer dries, the penetrant bleed out into the developer and thus marks out the flaws. The test area is checked in natural light or black (UV) light (depending on penetrant type).

THE TESTS ARE PERFORMED ON THE BASIS OF CUSTOMER'S REQUIREMENTS BY A COLORED OR FLUORESCENCE METHOD; TESTS ARE ACCREDITED AND PERFORMED BY A QUALIFIED PERSONNEL UNDER STN EN 9712 LEVEL II AND III.

Instrumentation equipment

The test is used to check both metallic and non-metallic materials. The penetration test is mainly used on non-ferrous materials in the aerospace industry and stainless steel products. The advantage of this test is low rate of costs and it is not so time-consuming. The disadvantage is that it only reveals surface flaws.
