This European Standard specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against Anobium punctatum (De Geer) by egg-laying and larval survival in wood which has been 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.

NOTE

This method can be used in conjunction with an ageing procedure, for example EN 73 .
