Special Analysis

Head of Working Group

"Driven by academic curiosity, what inspires me in my job as head of the accredited test lab are the fascinating moments constantly recurring. Both in the framework of user-oriented research and development work, and in connection with material characterizations for testing services – investigation and assessment of things unknown at first, of material properties hidden, can be compared with investigative work."

Head of Accredited Test Laboratory

Special Analysis

In addition to the standard tests we also use numerous special methods for failure and defect analysis in the different classes of materials (leather, collagen materials, leather fibre boards, coated textiles, textiles, films and plastics).
