Testing and Certificates
In our ISO 17025 accredited and NADCAP-MTL certified test laboratories, approximately 500,000 test orders are carried out annually according to 180 different accredited test methods. The central database for recording all test data, LISA-LIMS, has been in highly reliable use since 2003. In certification, around 50,000 acceptance test certificates are created annually on the basis of the test results from the companies and the test laboratories.

Our state-of-the-art chemical laboratories provide production with critical information for process control, product certification, and environmental monitoring. To determine the composition of metallic and non-metallic substances such as steel, non-ferrous alloys, input materials and by-products of stainless steel production, we use inorganic chemical analysis methods.
Process Analytics and Solids Analysis
Tasks: Analysis of solid samples with the aim of short response times with the highest precision and correctness at the same time.
Methods: X-ray and spark spectrometry as well as combustion analysis and melt extraction.
Wet Chemistry
Tasks: Trace analysis for process samples as well as determination of the main and minor components of difficult matrices, supply of solids analysis with certified calibration samples and reference materials, special raw material and waste analyses, analysis of environmentally relevant samples.Methods: Classical wet chemical analysis methods in combination with state-of-the-art optical spectrometry, mass spectrometry and chromatography.
Corrosion Testing
Tasks: Corrosion investigation of steels and alloys.
Absorption cooling, heat recovery heating and ventilation
Methods: Various methods in accordance with international standards and specific regulations for testing resistance to generally ablative corrosion, intercrystalline corrosion, stress corrosion cracking, pitting corrosion – including electrochemical test methods.
The heating energy supply of the new chemical laboratory will be ensured by decoupled industrial waste heat in the plant and at the same time the heating power requirement for the ambient air of the laboratory processes will be significantly reduced by a closed-loop system from the laboratory exhaust air.
In addition, cooling will be provided by an absorption refrigeration system with a cooling capacity of around 850 kW and cooling towers on the roof. Existing process waste heat potential from the plant will also be utilised as expulsion energy.
