What is BS EN 49-2 - Determination of the protective effectiveness against Anobium punctatum about?
BS EN 49-2 specifies a method for the determination of the protective effectiveness or the toxic values of a wood preservative against Anobium punctatum (De Geer) by egg-laying and larval survival in wood which has been treated previously by full impregnation. 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 in the laboratory by dilution of concentrates
- water-soluble materials, for example, salts.
Note: This method can be used in conjunction with an ageing procedure, for example, EN 73.
Who is BS EN 49-2 - Determination of the protective effectiveness against Anobium punctatum for?
BS EN 49-2:2015 on the determination of the protective effectiveness against Anobium punctatum is useful for:
- Forest preservationist
- Wood researchers
- Forest inspection personnel
- Forest safety organizations
Why should you use BS EN 49-2 - Determination of the protective effectiveness against Anobium punctatum?
BS EN 49-2:2015 describes a laboratory method of testing which gives a basis for assessment of the effectiveness of a wood preservative, against Anobium punctatum. BS EN 49-2 allows the determination of the concentration at which the product prevents the development of infestation from egg-laying.
The method simulates conditions that can occur in practice on timber that has been treated some time previously with a deeply penetrating wood preservative and on which eggs of Anobium punctatum are laid.
BS EN 49-2 provides one criterion by which the value of a product can be assessed. In making this assessment the methods by which the preservative 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.
What’s changed since the last update?
BS EN 49-2:2015 supersedes BS EN 49-2:2015 which is withdrawn. Significant technical differences between BS EN 49-2:2015 and BS EN 49-2:2015 are as follows:
- Generalization of material for preparing the egg-laying zones
- Introduction of new harmonized specifications for wood quality.
