32、rvative against wood destroying basidiomycetes. By using this method it is possible to determine the loading at which impregnated wood of a susceptible species may be regarded as adequately protected under the conditions of test. This laboratory method provides one criterion by which the value of a
33、product can be assessed, and this criterion should be used to judge the value of the preservative taking into account the methods of application likely to be used. The procedures described in this standard method are intended to be carried out by suitably trained and/or supervised specialists. Appro
34、priate safety precautions should be observed throughout the use of the standard. Any deviation, however small, from the procedures given in this standard can influence the results, so it is important that the procedures given in this method are followed precisely. 1 Scope This European Standard spec
35、ifies 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 t
36、he 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 laborat
37、ory 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.

These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisi
39、ons of any of these publications apply to this European Standard only when incorporated in it by amendment or revisions.

47、ssible to select other fungi on an optional basis 1) . 5.1.5 Maintenance of strains. The strains shall be maintained and treated (that is frequency of subculturing, alternation of culture media, etc.) in accordance with the instructions from their laboratory of origin (see Annex D.2). The parent str
48、ain shall be maintained in the laboratory of its origin such that its vigour is conserved and assured. 5.2 Products and reagents 5.2.1 Culture medium The culture medium is a malt agar medium with the following composition: malt extract in concentrated form: (50 0,5) g, in powder form: (40 0,5) g; ag
