Friedrich Eisenkolb Accredited Testing Laboratory

Competent, fast and flexible

More than 60 years ago, our eponym, Prof. Friedrich Eisenkolb, laid the foundation for our powder-metallurgical test laboratory in Thale, Germany. We are accredited through the Dakks (German Accreditation Body) in accordance with DIN EN ISO/IEC 17025:2018 for physical, mechanical-technological and analytical testing at metallic and powder metallurgical materials as well as testing of metal powder and testing of technical cleanliness.

Tests which are required for acceptance certification are conducted in close collaboration with authorized inspection agencies such as TUEF, Germanischer Lloyd, Lloyd’s Register etc.

Our team of 9 employees guarantees technical competence at the highest level and ensures promptness and flexibility for the solution of complex material-testing tasks.

Our laboratory is a certified training organization for material inspectors.
