EN 46-1:2016 (E) DIN EN 46-1:2016-11 5 Introduction This European Standard describes a laboratory method of testing which gives a basis for the assessme

30、nt of the preventive action of a wood preservative, when applied as a surface treatment, against recently hatched larvae of Hylotrupes bajulus, whereas the method for determining the toxic values against Hylotrupes bajulus (EN 47) provides a means of checking whether a preservative prevents attack b

31、y these larvae and prevents their survival within totally impregnated wood. This method makes it possible to determine whether recently hatched larvae are capable of boring through the treated surface of a susceptible wood species and of surviving in the untreated part of the test specimen. For this

32、 purpose, the procedure seeks to reproduce normal egg-laying conditions existing in cracks in wood, which provide the principal egg-laying sites. It takes account of the fact that, if larvae pass through the treated surface, they will then tunnel in the direction of the least protected regions of th

33、e wood. This laboratory method provides one criterion by which the value of a preservative can be assessed. In making this assessment, the methods by which the preservative may be applied should be taken into account. This test is of particular interest when applied to test specimens which have been

34、 subjected to an ageing procedure. It is further recommended that results from this test should be supplemented by those from other appropriate tests and, above all, by practical experience. When products which are very active at low concentrations are used it is very important to take suitable prec

35、autions 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, conditioning chambers and special tr

36、aining for personnel (see also Annex D for environmental, health and safety precautions). EN 46-1:2016 (E) DIN EN 46-1:2016-11 6 1 Scope This European Standard specifies a method for the determination of the preventive action of a wood preservative against recently hatched larvae of Hylotrupes bajul

37、us (Linnaeus) when the preservative is applied as a surface treatment to wood. 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-dispers

38、ible formulations as supplied or as prepared in the laboratory by dilution of concentrates; and water-soluble materials, for example salts. The method is applicable whether or not the test specimens have been subjected to appropriate ageing procedures. 2 Normative references The following documents,

41、finitions For the purposes of this document, the following terms and definitions apply. 3.1 representative sample sample having its physical and/or chemical characteristics identical to the volumetric average characteristics of the total volume being sampled SOURCE: EN 1001-2:2005, 4.71 3.2 supplier

42、 sponsor of the test (person or company providing the sample of wood preservative to be tested) Note 1 to entry: Adapted from EN 10012:2005, 4.83. EN 46-1:2016 (E) DIN EN 46-1:2016-11 7 4 Principle Depending on the test being carried out either: on a set of test specimens of a susceptible wood speci

43、es that is surface treated with a solution of the preservative; or if toxic values are to be determined, on several sets of test specimens of a susceptible wood species that are surface treated with a series of solutions in which the concentration of preservative is ranged in a given progression. Th

44、e treated test specimens are exposed to recently hatched larvae of Hylotrupes bajulus. The resulting attack is observed and compared with those in untreated control test specimens. If the preservative has been prepared in the laboratory by dilution of a concentrate or by dissolution of a solid, the

45、resulting attack is also compared to that in solvent or diluent treated control test specimens. 5 Test materials 5.1 Biological material 5.1.1 Hylotrupes bajulus (Linnaeus) larvae, within three days of hatching. 5.1.2 Source of larvae. Obtain the larvae from cultures reared, e.g. as described in Ann

46、ex B. 5.1.3 Provision of larvae. Collect larvae from eggs laid by different females. 5.1.4 Choice of larvae. Use a mixed batch of these larvae for the test. Use ten larvae per treated test specimen or control test specimen. 5.2 Products and reagents 5.2.1 Paraffin wax, for fixing the glass plate and

47、 for sealing the end faces of test specimens to be treated with solutions in all cases in which water is the continuous phase. NOTE Paraffin wax with a setting point of 52 C to 54 C has been found to be suitable. 5.2.2 Gelatin, for sealing the end faces of test specimens to be treated with solutions

48、 in which an organic solvent is the continuous phase. 5.2.3 Water, complying with grade 3 of EN ISO 3696. 5.2.4 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 that has a

49、 toxic effect on the insects. CAUTION Do not use benzene or other solvents which pose a health risk. 5.3 Apparatus 5.3.1 Culturing chamber, with air circulation, and controlled at (28 2) C and at a relative humidity of (70 5) %. 5.3.2 Conditioning chamber, well ventilated and controlled at (20 2) C and at a relative humidity of (65 5) %.
