“…Therefore, interpretation should be conducted by a qualified inspector of IRT [99] to ensure inspection qualities. Another problem is that color scales representing temperature values need to be set in proper temperature ranges to avoid overlooking delamination [95,[100][101][102]. For example, Washer et al [100] suggested the range of 2.2-4.4 • C for shaded areas.…”

“…[9] empfiehlt aus ähnlichen Untersuchungen für der Sonne zugewandte Oberflächen Messungen um die Mittagszeit und für sonnenabgewandte Stellen Inspektionen um Mitternacht. Auch [10] zeigt ähnliche Erkenntnisse. In [11] wurden Temperaturzeitverläufe von Fehl‐ und Referenzstellen zur Ortung von oberflächennahen Inhomogenitäten ausgewertet.…”
