本欧洲标准规定了通过完全浸渍以前处理过的木材中的产卵和幼虫存活来确定木材防腐剂对白僵菌(De Geer)的保护作用或毒性值的方法。此方法适用于: - 作为活性杀虫剂研究的水不溶性化学品; - 通过稀释浓缩物在实验室中提供或准备的有机配方; - 通过稀释浓缩物在实验室中提供或制备的有机水分散性制剂 - 水溶性物质,例如盐。 注意该方法可以与老化程序结合使用,例如EN 73
This European Standard specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against Anobium punctatum (De Geer) by egg-laying and larval survival 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; - organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates; - organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates, and - water-soluble materials, for example salts. NOTE This method can be used in conjunction with an ageing procedure, for example EN 73.
