Valid and reproducible non-destructive testing requires know-how and experience. A large number of national and international standards, which may differ depending on the respective industry, define the framework for the use of established and new methods. Particularly when optimizing and developing new methods and systems, current regulations must be observed and new procedures or equipment must be set up accordingly.
The Deutsche Akkreditierungsstelle (DAkkS) has granted the Fraunhofer IKTS NDT test lab flexible accreditation in categories 1 and 2 according to DIN EN ISO/IEC 17025 for four non-destructive testing methods. This status, which only very few testing laboratories achieve at all, allows the lab to modify procedures in the field of ultrasonic testing, eddy-current testing and acoustic emission technique as well as to develop them further and to create new methods. This ensures that, after appropriate validation, the new methods can be used by the customer in a similar way to standardized procedures. As a result, new testing technologies are implemented much earlier than standardization processes would normally allow. In the case of visual test procedures, the NDT lab is free to choose from standardized or equivalent testing procedures. This has the advantage that equivalent standards can be used for testing without having to obtain prior permission from the DAkkS.
In this way, methods developed at Fraunhofer IKTS can be validated in the field and then applied in a quality-assured manner.
The accreditation of the NDT test lab applies to manual and mechanized testing procedures (ultrasonic, eddy current, visual testing and acoustic emission technique) on metallic components, fiber-reinforced and ceramic materials and composites.
