29、s a surface treatment, against Anobium punctatum. It allows the determination of the concentration at which the product prevents the development of infestation from egg laying. It can also be used with formulations ready for use. The method simulates conditions which can occur in practice on timber
30、which has been treated some time previously with wood preservative applied by dip, brush or spray and on which eggs of Anobium punctatum are laid. This laboratory method provides one criterion by which the value of a product can be assessed. In making this assessment the methods by which the preserv
31、ative may be applied should be taken into account. It is further recommended that results from this test should be supplemented by those from other appropriate tests, and above all by comparison with practical experience. When products which are very active at low concentrations are used it is very
32、important to take suitable precautions to isolate and separate, as far as possible, operations involving chemical products, other products, treated wood, laboratory apparatus and clothing. Suitable precautions should include the use of separate rooms, areas within rooms, extraction facilities, condi
33、tioning chambers and special training for personnel. 1 Scope This Part of EN 49 specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against infestation by Anobium punctatum (De Geer) when the product is applied as a surface treatment to
34、 wood. This method is applicable to: water-insoluble chemicals which are being studied as active insecticides, or, organic 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 b
35、y dilution of concentrates, or, water-soluble materials, for example salts. NOTEThis method may be used in conjunction with an ageing procedure, for example EN 73. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These norm
36、ative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated refe
37、rences the latest edition of the publication referred to applies. ISO 835-1:1981, Laboratory glassware Graduated pipettes Part 1: General requirements. ISO 3696:1987, Water for analytical laboratory use Specification and test methods. 3 Definitions For the purposes of this Part of EN 49, the followi
38、ng definitions apply. 3.1 representative sample a sample having its physical or chemical characteristics identical to the volumetric average characteristics of the total volume being sampled 3.2 supplier the sponsor of the test 4 Principle Depending on the test being carried out either a set of test
39、 specimens of a susceptible wood species is surface treated with a solution of the preservative; or if toxic values are to be determined, several sets of test specimens of a susceptible wood species are surface treated with a series of solutions in which the concentration of preservative is ranged i
40、n a given progression. The treated test specimens are exposed to gravid females of Anobium punctatum. The number of eggs laid, the number of eggs hatched and the numbers of surviving larvae are observed and compared with those in untreated controls. If the preservative has been prepared in the labor
41、atory by dilution of a concentrate or by dissolution of a solid, the resulting attack is also compared to that in solvent or diluent treated controls.

42、s and apparatus 5.1 Biological material 5.1.1 Anobium punctatum (De Geer) Adult males and females in good condition. Adults to be used in the test shall be collected at daily intervals from naturally infested wood or laboratory culture (see Annex C). Use recently emerged adults which have been recen
43、tly collected; kept overnight in quarantine (see C.6); and then checked to ensure that they are undamaged, active and free from any infestation by mites. Determine the sex (see Annex B) of the collected and checked adults and place the males and females in separate containers. NOTEThe proportion of
44、males and females varies during the emergence period. 5.2 Products and reagents 5.2.1 Paraffin wax, for sealing the relevant surfaces of specimens to be treated with solutions in which water is the continuous phase. NOTEParaffin wax with a setting point of 52 C to 54 C has been found to be suitable.
45、 5.2.2 Gelatin, for sealing the relevant surfaces of specimens to be treated with solutions in which an organic solvent is the continuous phase. 5.2.3 Paste, for securing filter paper. The paste shall be starch-free, non-toxic to Anobium punctatum and insoluble in the product under test. NOTESodium
46、carboxymethyl cellulose, food grade, has been found to be suitable. 5.2.4 Water, complying with grade 3 of ISO 3696. 5.2.5 Solvent or diluent, a volatile liquid that will dissolve or dilute the preservative but does not leave a residue in the wood at the end of the post-treatment conditioning period
47、 that has a toxic effect on the insects. CAUTION. Do not use benzene or other solvents which pose a health risk. 5.2.6 Filter paper, ordinary quality, medium-fast grade. 5.2.7 Fine cloth, of cotton or linen, with a mesh aperture of 0,3 mm to 0,6 mm. 5.3 Apparatus 5.3.1 Culturing chamber, with air ci
48、rculation, controlled at (21 1) C, and at relative humidity (80 5) %. 5.3.2 Conditioning chamber, well ventilated, controlled at (20 2) C and relative humidity (65 5) %. NOTEThe conditioning of specimens may be carried out in the laboratory work area (see 5.3.4) provided that this has the conditions
49、 specified for the conditioning chamber (see 5.3.2). 5.3.3 Treatment vessel, of a material that does not react with the preservative under test, for example of glass for organic products and of polyethylene for salts containing fluorine. 5.3.4 Laboratory work area, well ventilated, where treatment of the test specimens is carried out. CAUTION. It is essential to follow safety procedures for handling flammable and toxic materials. Avoid excessive exposure of operators to solvents or their vapours. 5.3.5
