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, 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
-

The method is applicable whether or not the test specimens have been subjected to appropriate ageing procedures.
