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, 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; and
• - water-soluble materials, for example salts.

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