DIN EN 46-1:2016-11

This European Standard specifies a method for the determination of the preventive action of a wood preservative against recently hatched larvae 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. This method makes it possible to determine whether recently hatched larvae are capable of boring through the treated surface of a susceptible wood species and of surviving in the untreated part of the test specimen. This standard differs from DIN EN 46-1:2010-03 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. Evaluation of the test specimens with an X-ray machine has been made possible. 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.
