This document specifies a method for leaching, applicable to test specimens of wood or wood-based products which are subsequently subjected to biological tests. This document 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 can also be used for pre-conditioning of untreated wood, modified wood and wood-based panel products, whether they received preservative treatment or not.
