Tageslicht Eindringprüfung (PT)
Daylight penetrant testing (PT)

a) Daylight penetrant testing

Areas of application

The penetrant testing (PT), also called dye penetrant testing, serves the discovery of fine surface defects not visible to the human eye.

It is often used on non-magnetic materials. This method can of course also be used on magnetic materials.

The necessary prerequisite for a successful application of the method is that the defects of the material are open to the surface. The evaluation of the indications are done with daylight at a ratio of more than 500lx on the workpiece.

The method is mainly used in industry, such as in plants, equipment and vessels in shipbuilding, automotive, railway, pipeline construction, foundries, power plant equipment and in the chemical plants.

Our Service

We carry out the process with mobile service vehicles in your works and construction sites, as well as stationary at our own locations.

In use is only approved test equipment which meets the highest quality requirements.

This service we offer you worldwide.

Our employees are qualified and certified in the level 1-3 according to ISO 9712 and ASNT SNT-TC-1A and have years of experience with a variety of materials and components.

 

Fluoreszierende Eindringprüfung (PT)
Fluorescent penetrant testing (PT)

b) Fluorescent penetrant testing

Areas of application

The fluorescent penetrant testing (PT) also serves the discovery of fine surface defects not visible to the human eye.

It is often used on non-magnetic materials. This method can of course also be used on magnetic materials.

The necessary prerequisite for a successful application of the method is that the defects of the workpiece are open to the surface. Due to the luminous color pigments a contrast enhancement is created. The evaluation of the indications happens under UV radiation > 10 W / m² on the workpiece, and thus the human eye can see the indications quickly and safely.

The method is mainly used in industry, such as in plants, equipment and vessels in shipbuilding, automotive, railway, pipeline construction, foundries, power plant equipment and in the chemical plants.
