DEKRA Inspection

Gain insight into the condition of your equipment and possible fatigue or wear

Non-destructive testing (NDT)

NDT inspections for insights without failures

How do defects occur in a rail, wheel axle or sprocket? Is this on the surface or internal? For optimal asset lifecycle management, it is important to know where and why defects occur. The DEKRA experts think along with you about the right research method. For example, a non-destructive test (NDT). This allows us to investigate damage without breaking open a component. DEKRA offers NDT for materials, components, systems, equipment and assets.

NDT allows you to examine and inspect a component internally without having to break it. This gives you insight into the condition of your equipment and possible fatigue or wear, even if these are not visible on the surface. Moreover, you often do not have to interrupt work or only briefly.

The benefits of NDT

There are a number of benefits to NDT:
  • You can use the results obtained to improve the reliability and availability of components.
  • You will save money by not opening up something and will be able to use it again when testing is over.
  • You will save money if work processes are not brought to a halt - use of a railway track, for example.


DEKRA's experienced experts carry out non-destructive testing in various ways. We help you choose the right NDT method and determine the frequency of inspections. We work, among others, with the following techniques:
  • ultrasonic measurements (pulse echo, TOFD and Phased Array)
  • magnetic measurements
  • penetrating measurements
  • Eddy Current measurements
  • flow measurements
  • X-ray measurements
  • thermography
  • mechanical non-destructive testing and measurements

Our approach during NDT inspections

Before actually carrying out an NDT inspection, a DEKRA expert will schedule a meeting with you to discuss exactly what you want to know about your systems. The expert will use the information he/she gains in the meeting to prepare an inspection plan. Inspections, measurements and tests will then be carried out on the basis of this plan and be used to gather and analyse information and report on it. The NDT report will be available for you to access digitally for an unlimited period of time.
NDT inspections will be carried out on-site, at your premises, and in our lab. Another option is to have an expert from DEKRA guide your employees while they carry out an inspection themselves. If a component is inspected and found to be in order, DEKRA’s experts will return it to its usual place ready to be put back into use.
