Accredited testing laboratories for assured quality
In our ISO/IEC 17025 accredited test labs (STS 0026), we conduct chemical, mechanical and metallographic inspections. This ensures that we also comply with customer requirements and lay the foundation for improving the production process. Proof of the quality of our testing is provided by quality assurance in the form of accompanying and interlaboratory comparison tests. Our labs are equipped to be state-of-the-art and available for studies on behalf of external customers.
Testing services
The tests we run most frequently for our customers include tensile tests, Charpy V-notch impact tests, Vickers/Brinell/Rockwell hardness tests, analyses of steel purity, analyses of steel, grain size and layer thickness.
Our test activities include but are not limited to:
- Hardness tests under loads ranging from 0.25 g to 3000 kg (HRC, HBN, HV and low-load HV)
- Tensile tests with a maximum load of 1600 kN (yield strength, tensile strength, elongation and reduction in area)
- Notched bar impact-bending test at temperatures down to -60 C (450 J pendulum impact tester)
- Metallographic testing (case depth, micrographs and structural analyses, grain size, degree of purity, damage analyses, etc.)
- Chemical steel analyses (spectrometer analysis, wet-chemical analyses, etc.)
- Calibration lab (length, starting moment, temperature, weight, roundness and roughness) – not accredited
- Damage analyses of steel samples, incl. SEM/EDX – not accredited
- Manufacture of test samples according to standard or customer request
- Bending tests of concrete reinforcing steel bars – not accredited
