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.
