20、 which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2010, and conflicting national standards shall be withdrawn at the latest by May 2010. Attention is drawn to the possib

21、ility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 46-2:2006. The standard EN 46 is composed of two parts: EN 46-1, Wood preservatives Determ

23、vicidal 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 applied by surface treatment; Part 1 is required to determine the larvicidal effect of preservatives and P

Significant technical differences between this document and EN 46-2:2006 are as follows: a) For treatment by dipping sealing of all faces except the one which is exposed to the insects added; b

28、e, when applied as a surface treatment for timber, against eggs of Hylotrupes bajulus. In combination with EN 46-1 it provides a means of checking whether larvae may hatch from eggs laid on the treated wood surface and whether they are capable of boring through the treated surface and of surviving i

29、n the untreated part of the wood. This amended standard provides for the sealing of all but one lateral face when specimens are to be treated by dipping. When products which are very active at very low concentration are used, it is very important to take suitable precautions to isolate and separate,

30、 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 training for personnel (see also A

31、nnex D for environmental, health and safety precautions).

32、es a method for the determination of the preventive action of a wood preservative against eggs of Hylotrupes bajulus (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; org

33、anic formulations, as supplied or as prepared in the laboratory by dilution of concentrates; organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; or water-soluble materials, for example salts. The method is applicable whether or not the tes

34、t specimens have been subjected to appropriate ageing procedures. 2 Normative references The following referenced documents are indispensable for the application of this document.

39、method treated wood panels are offered to freshly mated Hylotrupes bajulus females. The hatching ability of the larvae on the treated timber is examined. When the ovicidal action is insufficient, the mortality of the hatched larvae on and/or in wood treated with the same formulation is also establis
