DIN EN 46-2:2016-11

This European Standard 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 water-insoluble chemicals which are being studied as active insecticides, organic formulations and organic water-dispersible formulations as well as water-soluble substances, for example, salts. In combination with DIN EN 46-1 the procedure provides a means of checking whether larvae may hatch from eggs laid on the treated wood surface and whether they are capable of boring through the treated surface and of surviving in the untreated part of the wood. This standard differs from DIN EN 46-2:2010-03 as follows: a) the requirements for wood quality have been harmonized with other testing standards. In addition, it is now possible to omit control test specimens treated with a solvent or diluent if only water has been used as a solvent or diluent. The committee responsible for this standard is NA 042-03-06 AA "Spiegelausschuss zu CEN/TC 38 und ISO/TC 165/SC 1 Dauerhaftigkeit von Holz und Holzprodukten" ("Mirror Committee of CEN/TC 38 and ISO/TC 165/SC 1 Durability of wood and wood-based products") at DIN.
