Wood preservatives; determination of eradicant action against larvae of anobium punctatum (De Geer) (laboratory method); amendment

This standard establishes a laboratory procedure for evaluating the efficacy of wood preservatives against larvae of furniture beetles. The method, known as the De Geer technique, is specifically designed to measure the killing power of chemical treatments applied to timber. It provides a controlled environment to assess how effectively a preservative can eliminate pests at the larval stage, which is a critical factor in ensuring the durability and longevity of wooden furniture and structural elements. The protocol outlines precise steps for preparing test specimens, exposing them to infested conditions, and subsequently analyzing mortality rates. By following this approach, manufacturers and regulatory bodies can verify that wood treatment processes meet necessary safety and performance criteria before products reach the market. The document serves as a technical reference for conducting consistent and reproducible assessments within a laboratory setting, focusing solely on the biological response of the target insect species to preservative exposure. It does not address field application methods or long-term performance in real-world conditions, but rather concentrates on the initial efficacy determination under standardized laboratory constraints.
