Arbitrational Analyses

In cases of dispute we compile arbitrational analyses, particularly in the field of precious metals.

Sampling taking and supply

We take and supply samples in Germany and abroad, whereby appropriately qualified specialists are frequently commissioned to act as subcontractors.

Materials Testing, Metallography

•  Determination of hardness (Brinell, Vickers,  Rockwell)
•  Tensile strength, yield point, expansion, E module
•  Structural examinations, hardening depths, layer  thicknesses
•  Analysis of galvanic and anodized coatings (coat  thickness, admittance, dielectric loss factor and  other coat properties)
•  Testing of anodized coatings on customers’  premises (e.g. on windows and facades)
•  Electric conductivity

Corrosion tests, climatic tests

•  Salt spray tests
•  Condensation water, constant and alternating  climate
•  Kesternich test
   All in accordance with German and international  norms
•  Climatic tests: - 40 to + 200° C with a defined  humidity

Expert reports for complaints and claims

•  For courts, industry and private
