We can examine your parts for surface faults using the penetration test. The procedure has proven its worth particularly for examining cracks that are open toward the surface.

In contrast to other surface testing methods, the colour penetration test can be applied in principle for all parts regardless of the material. This allows metallic workpieces and also your workpieces made of ceramic, glass and plastic to be tested reliably.

The non-destructive testing procedure can be carried out in daylight or fluorescently under UV light depending on the selected test equipment. This means that this procedure is highly suitable for installed components and workpieces where no other non-destructive procedure can be used due to the part size.


  • Mobile and stationary tests (under construction site conditions)
  • Weld testing
  • Testing installed parts (without their removal)
