EN 47 Wood Preservatives - Determination of Toxic Values ​​Against Hylotrupes Bajulus (Linnaeus) Larvae (Laboratory Method)

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 47 testing. This European standard specifies a method for the determination of toxic values ​​of a wood preservative against larvae of Hylotrupes bajulus (Linnaeus) introduced into previously fully impregnated wood.

This method applies to:

• Water-insoluble chemicals under investigation as active insecticides;
• Organic formulations prepared as supplied or by dilution of concentrates in the laboratory;
• Water-soluble materials such as salts.

This standard describes a laboratory test method that provides a basis for the overall assessment of the efficacy of a wood preservative against Hylotrupes bajulus by comparing the concentration at which the product prevents survival in fully impregnated wood with different classes of larvae.

This laboratory method provides a criterion by which the value of a preservative can be judged. In making this assessment, the methods by which the preservative can be applied should be considered. It is also recommended that the results from this test be supplemented by comparison with those from other appropriate tests, and above all practical experience.

When using products that are very active at very low concentration, it is critical to take appropriate measures to isolate and separate as much as possible from processes involving chemical products, other products, treated wood, laboratory apparatus and clothing. Appropriate measures should include the use of separate rooms, areas within rooms, extraction facilities, conditioning rooms and special training for staff.
