Publication date:   Jul 30, 2026

Scope

This document 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, or
- water-soluble materials, for example salts.
The method is applicable whether or not the test specimens have been subjected to appropriate ageing procedures.
