本文件规定了一种浸出方法，适用于随后进行生物处理的木材或木质产品的试样 测验。 本文件适用于: a） 在进行生物试验之前对试样进行预处理；或 b） 评估 通过比较受此程序处理的试样在生物试验中的性能与其他 没有经过任何浸出程序。 注:该方法也可用于未处理木材、改性木材和木质基木材的预处理 面板产品，不论是否经过防腐处理。

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.
