Phạm vi áp dụng / Scope of standard

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.
