* Upon agreement with the customer, other normative and technical documentation may be used in research and testing.

TÜV Thüringen Promservice has been working in this direction for many years and together has extensive experience in indirect and direct verification of equipment.

We also note that our company accompanies the indirect verification of impact drop machine at the NIST institute.

The company employs specialists in non-destructive testing of the 2nd and 3rd qualification levels, both according to the standards of the Russian Federation and European Norms, and ASNT.

We are ready to implement the following types of NK for you:
• Vortex-current method of control;
• Ultrasonic control;
• Visual control;
• Magnetic Powder Control;
• Thickness measurement
• Capillary control method;
• Electrical method.
