Wood preservatives - Determination of eradicant efficacy in preventing emergence of Anobium punctatum (De Geer)

This document specifies a method for the determination of the curative action of a wood preservative against infestation by Anobium punctatum (De Geer) when the product is applied as a surface treatment to wood.
This method is applicable to any surface-applied treatment that is intended to prevent emergence of adult beetles but not intended to kill larvae in infested timber.
NOTE 1 This method can be used in conjunction with an ageing procedure, for example EN 73.
NOTE 2 Products intended to kill larvae can be tested by the method described in EN 48.

Holzschutzmittel - Bestimmung der auf Schlupfverhinderung beruhenden bekämpfenden Wirksamkeit gegenüber Anobium punctatum (De Geer)

Dieses Dokument legt ein Verfahren zur Bestimmung der bekämpfenden Wirkung eines Holzschutzmittels gegen Befall durch Anobium punctatum (De Geer) fest, wenn das Produkt zur Oberflächenbehandlung auf Holz aufgetragen wird.
Dieses Verfahren ist für jede Oberflächenbehandlung anwendbar, die dazu bestimmt ist, den Schlupf ausgewachsener Käfer zu verhindern, aber nicht dazu gedacht ist, die Larven in befallenem Holz abzutöten.
ANMERKUNG 1   Dieses Verfahren kann in Verbindung mit einer Alterungsbeanspruchung angewendet werden, z. B. nach EN 73.
ANMERKUNG 2   Produkte zur Abtötung von Larven können durch das in EN 48 beschriebene Verfahren geprüft werden.

Produits de préservation du bois - Détermination de l'efficacité curative contre l'émergence d'Anobium punctatum (De Geer)

Le présent document décrit une méthode de détermination de l’action curative d'un produit de préservation du bois contre l’infestation d'Anobium punctatum (De Geer) lorsque le produit est appliqué au bois par un traitement de surface.
La présente méthode est applicable à tout traitement de surface qui est destiné à empêcher l'émergence d’insectes adultes mais non de tuer les larves dans le bois infesté.
NOTE 1   Cette méthode peut être utilisée conjointement avec une épreuve de vieillissement, par exemple selon l'EN 73.
NOTE 2   Les produits destinés à tuer les larves peuvent être soumis à essai selon la méthode décrite dans l’EN 48.

Zaščitna sredstva za les - Ugotavljanje učinkovitosti preventivnega delovanja proti navadnemu trdoglavcu Anobium punctatum (De Geer)

Ta dokument določa metodo za ugotavljanje učinkovitosti obnovitvenega delovanja zaščitnega sredstva za les proti navadnemu trdoglavcu Anobium punctatum (De Geer), ko je izdelek uporabljen v sklopu površinske obdelave
lesa.
Ta metoda se uporablja za vse površinske obdelave lesa, ki so namenjene preprečevanju pojavu odraslih hroščev, ne pa za ubijanje ličink v prizadetem lesu.
OPOMBA 1: Ta metoda se lahko uporablja v povezavi s postopkom staranja, na primer EN 73.
OPOMBA 2: Proizvode, namenjene za ubijanje ličink, je mogoče preskusiti po metodi, opisani v standardu EN 48.

Introduction
This document describes a laboratory method of test which gives a basis for assessment of the eradicant
efficacy of a wood preservative, in preventing emergence of Anobium punctatum. It determines the lethal
effects of an insecticidal product, deposited by surface application, on beetles attempting to emerge
through treated wood surfaces.
The method has been developed to assess the efficacy of eradicant formulations based on non-
penetrating fluids which act only on emerging adult beetles and not at depth on larvae established in the
wood.
The method simulates conditions which can appear in practice where a length of timber infested with
Anobium punctatum is treated on all the sides from which emergence of beetles is possible.
This laboratory method provides one criterion by which the value of a product can be assessed. In making
this assessment, the methods by which the preservative may be applied should be taken into account. It
is further recommended that results from this test should be supplemented by those from other
appropriate tests, and above all by comparison with practical experience.
When products which are very active at low concentrations are used, it is very important to take
