Wood preservatives. Determination of the protective effectiveness against Lyctus brunneus (Stephens) - Application by impregnation (laboratory method) Ingestion-build-54484 the reproducibility and repeatability of1 Scope This Part of EN 20 specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against infestation by Lyctus brunneus (Stephens) 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
