Annotation of standard text ČSN EN 47 (490695):

This European Standard specifies a method for the determination of the toxic values of a wood preservative against the larvae of Hylotrupes bajulus (Linnaeus), introduced into wood treated previously by full impregnation.
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
