Penetrant Testing (PT)

PELZ Eindringprüfung PT

Penetrant Testing (PT) Your partner for material & quality testing

The PT colour penetration test (the so-called penetrant testing) is used for the detection of fine surface defects which are not visible to the human eye and works through the capillary effect.

It is preferably used in the case of non-magnetizable raw materials, but can also be used in the case of magnetizable raw materials.

The necessary prerequisite for a successful application of the PT colour penetration test is that the flaws are open toward the surface of the raw material. The evaluation of the indicators is carried out under daylight and/or artificial light with more than 500 lx on the workpiece.

The PT colour penetration testing is mainly used in the industrial field, for example in installation construction, apparatus and container construction, shipbuilding, automotive, railway construction, pipeline construction, in foundries, power plants and chemical installations.

Fluorescent PT Penetration Test – PT Flour Fields of application

The flourescent PT colour penetration test (the so-called penetrant testing) is applied for the detection of fine surface defects which are not visible to the human eye and works through the capillary effect.

It is preferably used in the case of non-magnetizable raw materials, but can also be applied in the case of magnetizable raw materials.

The necessary prerequisite for a successful application of the fluorescent PT colour penetration test is that the flaws are open toward the surface of the piece. The evaluation of the test surface is carried out under UV radiation with > 10 W/m² on the workpiece. Due to the fluorescent colour pigments of the test agent, for the eye this results in an improved contrast optimising the defect detection ability.

This method is mainly used in the industrial field, for example in installation, apparatus and container construction, shipbuilding, automotive, railway construction, pipeline construction, in foundries, power plants and chemical installations.

Our services

We carry out the mobile method of fluorescent PT colour penetration testing for you by means of emergency vehicles in your production and construction sites, as well as the stationary procedure on test installations at our own locations.

Small components can be tested on our PT test lines as bulk material or material in certain quantities with high throughput. Specially selected test equipment is used for the respective test task and requirement level of different system classes.

We offer you the mobile service all around the globe.

Our employees are qualified and certified in the levels/levels 1–3 according to the standards EN 473, ISO 9712 and ASNT-SNT-TC-1A and have many years of experience with a wide variety of raw materials and components.
