T1 - A round robin test of flash thermography – detectability and quantification of artificial and natural defects in CFRP and metal structures N2 - Within the scope of a DIN INS project, a flash thermography round robin test that evaluates reliability, comparability, and efficiency of different testing situations was organized. The results give information about the detectability of defects, e.g. depending on their size and depth, the evaluation methods and the materials used. Besides, the influences of equipment and parameters used by the participants on the results were analysed. All of the quantitative results as well as the feedback given by the participants will be presented in a DIN committee in order to contribute to a flash thermography standard.

T1 - Ringversuche zur Blitzthermografie N2 - Im Rahmen des INS-Projekts „Durchführung von Ringversuchen zur Normung und Standardisierung der aktiven Thermografie mit Blitzlichtanregung“ wurden Ringversuche durchgeführt, die die Zuverlässigkeit, Vergleichbarkeit und Effektivität der Blitzthermografie für unterschiedliche Prüfprobleme nachweisen sollten. Weiterhin sollten diese Untersuchungen als Methodenvalidierungsstudie die Richtigkeit und Präzision der Blitzthermografie nachweisen und Vergleichsinformationen unterschiedlicher Geräteausstattungen liefern. Im Normausschuss NA 062-08-27 AA „Visuelle und thermografische Prüfung“ des DIN werden die Ergebnisse die Erarbeitung eines Normentwurfs zur Blitzthermografie unterstützen. In diesem Beitrag werden die Ringversuche beschrieben und ausgewählte Ergebnisse präsentiert.

T1 - A round robin test on flash thermography N2 - A round robin test on flash thermography was organized within the scope of a standardization research project. This test gives information on reliability, comparability and efficiency of different testing situations. Data recorded on metal and CFRP test specimens with flat bottom holes (FBH) were analysed by evaluating the detectability and by calculating the signal-to-noise ratio (SNR) of the defect signatures as a function of defect parameters. For the investigation of the influence of material properties on the spatial resolution as well as on penetration depth, test specimens made of steel and copper with crossed notches and a notch ramp were constructed and investigated. Here, the minimum resolvable notch distance and the maximum detectable depth of the ramp were analysed.
