In addition to the standardized test methods that we offer as a service within the scope of our accreditation, there are a large number of other test methods, some of which are not yet subject to standardization. These are taken up by our colleagues in research and development in order to describe the final product quality or a process condition during production. Methods based on ultrasound, X-ray including computer tomography, thermography, terahertz, radar and optical camera technology, among others, are used. Here you will find support in the identification of the most suitable test method under physical, chemical, technical and economic aspects up to commercial system development and integration at your site.
