Overview
EN 47:2016 - published by CEN - specifies a laboratory method to determine the toxic values of wood preservatives against larvae of Hylotrupes bajulus (Linnaeus) introduced into wood previously treated by full impregnation. The method applies to water‑insoluble chemicals, organic formulations (including water‑dispersible types), and water‑soluble materials (eg salts). Tests may be performed on specimens that have or have not undergone ageing procedures. EN 47:2016 supersedes EN 47:2005 and adds harmonized wood‑quality specifications.
Key topics and technical requirements
- Test principle: impregnate sets of susceptible wood specimens with a range of preservative concentrations, introduce Hylotrupes bajulus larvae, and determine survival rates at fixed intervals to derive toxic values.
- Biological material: two larval categories are defined - Category 1 (larvae ≤ 3 days after hatching) and Category 2 (larvae 50–150 mg). Guidance is given for sourcing, culturing and selecting healthy larvae (see Annex B).
- Wood specimens: reference species is Scots pine (Pinus sylvestris). Specimens are prepared to precise dimensions after conditioning: (50 ± 0.5) mm × (25 ± 0.5) mm × (15 ± 0.5) mm; nominal volume = 18.75 cm3. Wood quality rules (sapwood, growth rate, ring proportions) are specified.
- Test materials & apparatus: permitted solvents and water quality (EN ISO 3696), treatment vessels, vacuum impregnation equipment, conditioning and testing chambers with controlled temperature and relative humidity (eg conditioning chamber (20 ± 2) °C, RH 65 ± 5 %; culturing chamber (28 ± 2) °C, RH 70 ± 5 %), drill sizes for larval introduction and optional X‑ray radiography.
- Procedure & reporting: preparation of at least five test concentrations, control specimens (untreated and solvent/diluent controls), post‑treatment conditioning, larval introduction, observation and expression of results and full test reporting (Annex A example included).
- Safety: specific environmental, health and safety precautions are recommended (Annex D), particularly when handling highly active formulations or volatile solvents.
Applications and users
- Who uses EN 47:2016: product manufacturers, independent testing laboratories, research institutions, regulatory bodies, and specification writers assessing or demonstrating insecticidal efficacy of wood preservatives against Hylotrupes bajulus.
- Practical value: provides reproducible laboratory data for product development, comparative efficacy assessment, registration dossiers and quality control of preservative treatments for timber protection against wood‑boring larvae.
