Laboratories
Performs full examination of mechanical, chemical and metallographic properties of steel and metallic materials and input raw materials in general. Laboratories are owners of the accreditation certificates pursuant to the ČSN EN ISO/IEC 17025 standard and are included into the system certified by ISO 9001, members of an international association of measuring, testing and analytical labs Eurolab-cz, members of Czech Laboratories Association and testing facilities with audited activities, while they attend interlaboratory comparison tests regularly for the purpose of securing the highest possible quality of their results.
