Wood preservatives - Determination of the preventive action against Hylotrupes bajulus (Linnaeus) - Part 2: Ovicidal effect (laboratory method)

This part of EN 46 specifies a method for the determination of the preventive action of a wood preservative against eggs of Hylotrupes bajulus (Linnaeus) when the preservative is applied as a surface treatment to wood.
This method is applicable to:
¾   water-insoluble chemicals which are being studied as active insecticides,
¾   organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates,
¾   organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates, or
¾   water-soluble materials, for example salts.
The method is applicable whether or not the test specimens have been subjected to appropriate ageing procedures.

Holzschutzmittel - Bestimmung der vorbeugenden Wirkung gegenüber Hylotrupes bajulus (Linnaeus) - Teil 2: Ovizide Wirkung (Laboratoriumsverfahren)

Dieser Teil von EN 46 legt ein Verfahren zur Bestimmung der vorbeugenden Wirkung eines Holzschutzmittels gegenüber Eiern von Hylotrupes bajulus (Linnaeus) fest, wobei das Holzschutzmittel zur Oberflächenbehandlung des Holzes verwendet wird.
Das Verfahren gilt für:
-   wasserunlösliche Chemikalien, die als wirksame Insektizide untersucht werden, oder
-   organische Formulierungen im Anlieferungszustand oder in Form von im Laboratorium hergestellten Verdünnungen von Konzentraten, oder
-   organische, in Wasser dispergierbare Formulierungen im Anlieferungszustand oder in Form von im Laboratorium hergestellten Verdünnungen von Konzentraten, oder
-   wasserlösliche Stoffe, zum Beispiel Salze.
Das Verfahren gilt unabhängig davon, ob die Prüfkörper einer angemessenen Alterungsbeanspruchung ausgesetzt wurden oder nicht.

Produits de préservation du bois - Détermination de l'action préventive contre Hylotrupes bajulus (Linnaeus) - Partie 2 : Effet ovicide (Méthode de laboratoire)

La présente partie de l'EN 46 prescrit une méthode de détermination de l’action préventive d'un produit de
préservation du bois contre les oeufs d’Hylotrupes bajulus (Linnaeus) lorsque le produit de préservation est
appliqué au bois par un traitement de surface.
La présente méthode est applicable :
-aux produits chimiques non hydrosolubles étudiés en tant que matières actives insecticides ;
-aux formules organiques telles qu'elles sont fournies ou préparées au laboratoire par dilution de concentrés ;
-aux formules organiques hydrodispersables telles qu'elles sont fournies ou préparées au laboratoire par
dilution de concentrés ; ou
-aux produits solubles dans l’eau, par exemple aux sels.
Cette méthode s’applique à des éprouvettes d’essai ayant subi ou non des épreuves de vieillissement appropriées.
