Wood preservatives - Determination of the protective effectiveness against Lyctus brunneus (Stephens) - Part 2: Application by impregnation (Laboratory method)
This part of EN 20 specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against infestation by Lyctus brunneus (Stephens) in wood which has been treated previously by full impregnation. This method is applicable to: - water-insoluble chemicals which are being studied as acitve insecticides, or; - organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates.
Holzschutzmittel - Bestimmung der vorbeugenden Wirkung gegenüber Lyctus brunneus (Stephens) - Teil 2: Anwendung durch Volltränkung (Laboratoriumsverfahren)
Dieser Teil von EN 20 legt ein Verfahren fest zum Bestimmen der vorbeugenden Wirkung oder die Grenze der Wirksamkeit eines Holzschutzmittels gegen Befall durch Lyctus brunneus (Stephens), bei dem das Schutzmittel durch Volltränkung in das Holz gebracht wird. Dieses Verfahren ist anwendbar für: - nicht wasserlösliche chemische Erzeugnisse, die als Wirkstoffe untersucht werden; - nicht wasserlösliche organische Erzeugnisse im Anlieferungßustand oder in der Form, wie sie im Laboratorium aus Konzentraten hergestellt werden.
Produits de préservation du bois - Détermination de l'efficacité protectrice vis-à-vis de Lyctus brunneus (Stephens) - Partie 2: Application par traitement en profondeur (Méthode de laboratoire)
La présente partie de l'EN 20 prescrit une méthode de détermination de l'efficacité protectrice ou du seuil d'efficacité d'un produit de préservation du bois, introduit par imprégnation totale du bois, vis-à-vis de Lyctus brunneus (Stephens), par l'observation de la ponte et du taux de survie des larves. La présente méthode est applicable: - soit aux produits chimiques non hydrosolubles étudiés en tant que matières actives; - soit aux formules organiques telles qu'elles sont livrées ou obtenues en laboratoire à partir de concentrés.
