Durability of wood and wood-based products - Accelerated ageing of treated wood prior to biological testing - Evaporative ageing procedure

This document specifies an evaporative ageing procedure, applicable to test specimens of wood which have been previously treated with a wood preservative, in order to evaluate any loss of effectiveness when these test specimens are subsequently subjected to biological tests.

Dauerhaftigkeit von Holz und Holzprodukten - Beschleunigte Alterung von behandeltem Holz vor biologischen Prüfungen - Verdunstungsbeanspruchung

Dieses Dokument legt eine Verdunstungsbeanspruchung für Prüfkörper, die mit einem Holzschutzmittel behandelt wurden, fest. Die Beanspruchung dient dazu, eine mögliche Abnahme der Wirksamkeit des Holzschutzmittels zu erfassen, wenn diese Prüfkörper anschließend biologischen Prüfungen unterzogen werden.

Durabilité du bois et des produits dérivés - Épreuves de vieillissement accéléré des bois traités avant essais biologiques - Épreuve d'évaporation

Le présent document spécifie une méthode d'évaporation, applicable à des éprouvettes de bois préalablement traitées à l'aide d'un produit de préservation, en vue d'apprécier la perte éventuelle d'efficacité lorsque ces éprouvettes sont ultérieurement soumises à des essais biologiques.
