BS 5218:1989

What is BS 5218- Toxic values against Anobium punctatum about?

BS 5218 discusses wood preservatives. BS 5218 specifies a method for the determination of the toxic values of a wood preservative against larvae of Anobium punctatum (De Geer), introduced into the wood which has been treated previously by full impregnation.

This method in BS 5218 is applicable to:

• Water-insoluble chemicals which are being studied as active insecticides
• Organic water-insoluble 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

Who is BS 5218 - Toxic values against Anobium punctatum for?

BS 5218 on toxic values against Anobium punctatum is useful for:

• Wooden products manufacturers
• Furniture manufacturers
• Testing laboratories
• Quality control personnel

Why should you use BS 5218- Toxic values against Anobium punctatum?

Although an infestation normally starts from egg-laying, a larval transfer test is applicable when considering the situation of treated wood being put in contact, during repair work, with wood that might be infested.

BS 5218 describes a laboratory method of test which gives a basis for the assessment of the effectiveness of a wood preservative against Anobium punctatum. It allows the determination of the concentration at which the product completely prevents the survival of Anobium punctatum larvae in impregnated wood of a susceptible species. This laboratory method in BS 5218 provides one criterion by which the value of a product can be assessed.
