DS/EN 49-2:1994 Wood preservatives-Determination of the protective effectiveness against Anobium punctatum (De Geer) by egg-laying and larval survival-Part 2:Application by impregnation (Laboratory method)
This Part of EN 49 specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against Anobium puiutatum (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 or;
- organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates; or
- organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; or
- water-soluble materials, for example salts.
NOTE. This method may be used in conjunction with an ageing procedure, for example EN 73.
