    Description / Table of Contents: Es wird das Bewitterungsverhalten von Blei/Barium/Cadmium-bzw. Barium/Cadmium-stabilisierten Profilen mit neuentwickelten, schwermetallfreien Profilen, sogenannten HMF Profilen verglichen.Die Bewitterungsprüfung erfolgte in Freien, im Xenotest 450, QUV(A), und QUV(B). Verfolgt wurden die farbmetrischen Werte (ΔE, ΔL, ΔA, ΔB) und der Glanzverlust in Abhängigkeit von der Bewitterungsdauer. wahrend im QUV(B) fur die Praxis unbrauchbare Ergebnisse erhalten wurden, korrelieren die QUV(A) Gesamtfarbdifferenzergebnisse sehr gut mit den Freibewitterungsergebnissen. Die HMF stabilisierten Profile sind im Oberflächenangriff den Standard Blei/Barium/Cadmium-Profilen gleichwertig, wenn nicht überlegen. In der Farbmetrik verhalten sich die neuentwickelten HMF Profile gleichwertig den Blei/Barium/Cadmium Standardprofilen.
    Notes: The weathering behaviour of lead/barium/cadmium-respectively barium/cadmium-stabilized profiles has been compared with new developed profiles which are free from heavy metals, the so-called HMF profiles.The weathering tests have been made out doors, in Xenotest 450, QUV(A), and QUV(B). The colourmetric values (ΔE, ΔL, ΔA, ΔB) and the loss of brightness were measured in dependence of weathering time. The results of QUV(A) measurements were not suitable for practical application, but the findings of the total colour difference of QUV (A) measurements correlate very well with the results of out door weathering. With respect to the surface attack HMF-stabilized profiles are equivalent to the lead/barium/cadmium standard profiles or even superior. The colourmetric behaviour of the new developed HMF profiles is equivalent to the lead/barium/cadmium standard profiles.
