Penetrant Testing

Penetrant testing (PT) is a widely applied non-destructive inspection method, in order to identify surface-breaking defects in non-porous materials such as metals or ceramics. With our broad range of approved and highly efficient technologies and equipment we can support our customer in many ways.

Penetrant testing is a well-recognized inspection method to detect e.g. casting, forging and welding surface defects such as cracks, overlapping, folds, pinholes or other bonding failures. The so called 'penetrant system' consists of the penetrant itself, a penetrant remover and finally a developer, which helps to increase the contrast and pull out the remaining penetrant at the end of the inspection process. Whereas fluorescent penetrants are required for the part inspection under UV(A) light, color-contrast penetrants are widely used for the inspection under white light.


Approved fluorescent and color-contrast penetrants

Benefit from a broad range of fluorescent and color-contrast penetrants as well as all relevant removers and developers. With Ardrox® NDT products we are well acquainted with the high standards in the aerospace field for many years. Additionally, the high quality of the available NDT products and services has also convinced the automotive industry and its component supplier market, general industry and all areas of energy generation and transportation. The multiple approvals of our Britemor® and Checkmor® PT products are proof of this.
