Our Services

Quality is our top priority. So that you can trust our results, we have been using and continuously improving a quality management system accredited according to DIN EN ISO/IEC 17025 since the early 1990s.

We offer you:

  • Reproducible Results With the Maximum Transparency

Through the regular monitoring of testing equipment, participation in interlaboratory tests, gapless documentation, measurement uncertainty estimation, and much more, a high degree of accuracy of results is ensured and communicated with the client as desired.

  • Support in the Interpretation of Measurement Data

Close intermeshing of FGK’s raw materials and materials testing with the other business units of research, development, and consulting, industrial project completion, and the lengthy practical experience of FGK’s employees ensure that each testing order is assigned to the appropriate field and the best available state of the art.

  • Process-Integrated Solutions

When necessary, we not only compare measurements with legal limits or other requirements but also offer process-integrated solutions for materials development or environmental Technology.

If you have any questions on the nature and/or scope of required services, our qualified employees will be happy to advise you. We also invite you to visit us at any time and convince yourself of the high quality standard of our testing laboratory and state-of-the-art Equipment.
