Wood preservatives - Determination of toxic values against Reticulitermes species (European termites) (Laboratory method)

This document specifies a method for the determination of the toxic values of a wood preservative against the Reticulitermes species of European termites ). This method is applicable to: - water-insoluble chemicals which are being studied as active insecticides; - organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; and - water soluble materials, for example salts. NOTE This method can be used in conjunction with an ageing procedure, for example EN 73.

- organische, in Wasser dispergierbare Formulierungen in deren Anlieferungszustand oder in Form von im Laboratorium hergestellten Verdünnungen von Konzentraten; und
- wasserlösliche Stoffe, zum Beispiel Salze. ANMERKUNG Das Verfahren kann in Verbindung mit einer Alterungsbeanspruchung, zum Beispiel nach EN 73 oder EN 84, angewendet werden.

Produit de préservation du bois - Détermination du seuil d'efficacité contre les termites européens du genre Reticulitermes (Méthode de laboratoire)

La présente norme européenne décrit une méthode de détermination du seuil d’efficacité d'un produit de
préservation du bois contre les espèces de termites européens du genre Reticulitermes 1)
Cette méthode s'applique :
- aux produits chimiques non hydrosolubles étudiés en tant que matières actives ;
- aux formulations organiques hydrodispersables telles qu'elles sont fournies ou préparées au laboratoire
par dilution de concentrés ; et
- aux-produits hydrosolubles, par exemples des sels.
NOTE Cette méthode peut s'appliquer conjointement à une épreuve de vieillissement, par exemple l'EN 73 ou
l'EN 84.

Zaščitna sredstva za les - Ugotavljanje toksičnih vrednosti proti Reticulitermes santonensis (evropskim termitom) (laboratorijska metoda)

Ta evropski standard določa metodo za ugotavljanje toksičnih vrednosti zaščitnih sredstev za les proti vrsti evropskih termitov Reticulitermes. Ta metoda se uporablja za: – v vodi netopne kemikalije, ki se preučujejo kot aktivni insekticidi, – organske formulacije, ki dispergirajo v vodi in so dobavljene ali pripravljene v laboratoriju z redčenjem koncentratov ter – v vodi topne materiale, na primer sol.

1) The method can be applied not only to different species of Reticulitermes, but also to other species of the family of the Rhinotermitidae, adapting the conditions of temperature and humidity where necessary to the specific requirements of the species concerned. 2) In providing biological validation of individual species, it is essential that the locality of origin of each test termite species is given. The description of the locality should at least include the district name. SIST EN 117:2013
