This part of the EN 20 series specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against infection by Lyctus brunneus (Stephens) in wood which has been treated previously by full impregantion.
This method is applicable to:
- water-insoluble chemicals which are being studied as active insecticides; or
- organic formulsation, as supplied or as prepared in the laboratory by dilution of concentrates.
This method is applicable to water-based preservatives.
NOTE This method can be used in conjuction with ageing procedures, which do not remove the added nutrient.

This document specifies a method for the determination of the curative action of a wood preservative against infestation by Anobium punctatum (De Geer) when the product is applied as a surface treatment to wood.
This method is applicable to any surface-applied treatment that is intended to prevent emergence of adult beetles but not intended to kill larvae in infested timber.
NOTE 1 This method can be used in conjunction with an ageing procedure, for example EN 73.
NOTE 2 Products intended to kill larvae can be tested by the method described in EN 48.

This document provides guidance on how to apply curative acting wood preservatives by surface application, by filling pre-drilled holes, and by pressure impregnation through pre-drilled holes. It lists methods in a standardized form followed by additional detailed interpretive information.
This document also includes necessary preparations of structural timber prior to this kind of treatment. It gives guidance on how to calculate necessary retentions for filling pre-drilled holes or for pressure impregnation from test results obtained from surface applications (e.g. EN 1390).
