This document specifies a method for the leaching of test specimens of wood which are used in the testing of the biological efficacy of wood preservatives. This standard is applicable to: a) the pre-conditioning of test specimens prior to their being subjected to a biological test ; or b) assessment of loss of effectiveness by comparing the performance in a biological test of treated test specimens subjected to this procedure with others that have not undergone any leaching procedure. NOTE The method may also be used for pre-conditioning of wood-based panel products which may or may not have received preservative treatment.

This document specifies a method for the determination of the eradicant action of a surface application of a fast and a slow acting wood preservative product or a deferred acting wood preservative product on timber infested with larvae of Hylotrupes bajulus (Linnaeus). This method is applicable to: 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 products, for example, salts. NOTE An ageing procedure cannot be combined with this method.
