What is BS EN 47- Wood preservatives about?
BS EN 47 discusses wood preservatives. BS EN 47 specifies a method for the determination of the toxic values of a wood preservative against the larvae of Hylotrupes bajulus (Linnaeus), introduced into wood 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
- And water-soluble materials, for example, salts
Note: The method is applicable whether the test specimens have been subjected to appropriate ageing procedures.

Why should you use BS EN 47- Wood preservatives?
BS EN 47 provides a laboratory method of testing that gives a basis for the general assessment of the effectiveness of a wood preservative against Hylotrupes bajulus by determination and comparison with different classes of larvae, of the concentration at which the product prevents their survival is totally impregnated wood of a susceptible species.
BS EN 47 provides you with a method that provides a 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 considered. 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.
