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:
Note: This method can be used in conjunction with an ageing procedure, for example, EN 73.
BS EN 49-2:2015 on the determination of the protective effectiveness against Anobium punctatum is useful for:
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.
BS EN 49-2:2015 supersedes BS EN 49-2:2015 which is withdrawn.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:
