scope:

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: water-insoluble chemicals which are being studied as active insecticides, organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates, organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates, or water-soluble materials, for example salts. The method is applicable whether or not the test specimens have been subjected to appropriate ageing procedures.
