Zerstörungsfreie Prüfung - Ein Werkzeug der Qualitätssicherung

The contribution introduces into the mew directions to use nondestructive testing in quality management. The quality test as al last step after finishing in the production is indispensable for products with safety-related applications and inservice inspections are legal demands during a component life time. Nondestructive Testing sensors give access to other quantities than speed, measure, flux, etc. - mainly intrinsic material properties are determined. Quality has to be designed and developed. Therefore nondestructive testing is introduced in the early phases of product design. Not under the pressure of cyclic work here even microscopic techniques are of interest to illuminate the state of product development.
