22、upersedes EN 46-1:2005.

23、ion of the preventive action against recently hatched larvae of Hylotrupes bajulus (Linnaeus) Part 2: Ovicidal effect (laboratory method) EN 46 consists of two parts to enable preventive action of wood preservatives, against recently hatched larvae of Hylotrupes bajulus, which are intended to be app

Significant technical differences between this document and EN 46-1:2005 are as follows:

25、a) For treatment by dipping sealing of all faces except the one which is exposed to the insects added; b) New Annex E for extending the test duration for slow acting and deferred effect formulations added with the double number of test specimens and half number of insects; c) Requirements for the se

29、an Standard describes a laboratory method of testing which gives a basis for the assessment 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 Hylotru

30、pes bajulus (EN 47) provides a means of checking whether a preservative prevents attack by 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 susce

31、ptible wood species and of surviving in the untreated part of the test specimen. For this 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 tre

32、ated surface, they will then tunnel in the direction of the least protected regions of the 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 ac

33、count. This test is of particular interest when applied to test specimens which have been 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

34、are very active at low concentrations are used it is very 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 separa

35、te rooms, areas within rooms, extraction facilities, conditioning chambers and special training for personnel (see also Annex D for environmental, health and safety precautions).

37、 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-dispersible formulations as supplied or as prepared i

38、n 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 reference The following referenced documents are indispensable for the applicatio

43、d out either: on a set of test specimens of a susceptible wood species 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 th

44、e concentration of preservative is ranged in a given progression. The 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 labora

45、tory by dilution of a concentrate or by dissolution of a solid, the 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 larv

46、ae. Obtain the larvae from cultures reared, e.g. as described in Annex 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 Prod

47、ucts and reagents 5.2.1 Paraffin wax, for fixing the glass plate and 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

48、sealing the end faces of test specimens to be treated with solutions 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 toxic effect on the insects.
