适用范围：This European Standard specifies a method for determining the toxic values of wood preservatives previously introduced into the wood by full impregnation against wood destroying basidiomycetes cultured on an agar medium. This method is applicable to products which are capable of achieving uniform and complete penetration of the test specimens including: —water-insoluble chemicals which are being studied as active ingredients; or —organic water-insoluble 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 which are capable of achieving uniform and complete penetration of test specimens (see Clause 7) by the procedure described in 8.2.2; or —water-soluble products, for example salts. NOTE This method may be used in conjunction with an ageing procedure, for example EN 73.
