Abstract

Critically analyzing accelerated aging methods, the following items are summarized with respect to the conditions of weathering wood based panels. 1) Performance requirements and their transformation into property levels. 2) Chemical structure and bonding of wood based panels. 3) Short and long term effects of moisture, temperature and their cyclic influence as well as related chemical reactions and physical mechanisms. 4) Accelerating factors which are useful in artificial aging. Examples are given from an experimental comparison of panels subjected to several accelerating methods and to exterior exposure. Based on this analysis, proposals are made how to select suitable procedures to accelerate the aging of wood based panels.

Zusammenfassung

Die krítische Betrachtung von beschleunigten Verfahren zur Prüfung der Wetterbeständigkeit von Holzwerkstoffplatten nimmt zusammenfassend zu folgenden Punkten Stellung: 1) Anwendungsbedingte Anforderungen und ihre Überführung in meßbare Eigenschaften. 2) Chemische Zusammensetzung und Bindungen in diesen Platten. 3) Kurz-und langfristige Einwirkungen von Feuchtigkeit. Temperatur in entsprechneden Klimazyklen mit zugchörigen chemischen Reaktionen und physikalischen Mechanismen. 4) Beschleunigungsfaktoren, welche für die künstliche Schnellbewitterung geeignet sind. Diese Punkte werden durch Beispiele aus einem Vergleich von Schnellbewitterungsmethoden belegt. Verbesserte Methoden für die beschleunigte Bewitterungsprüfung werden vorgeschlagen.
